Bitesized: Sharing the value

Conner Drew | Elijah Parker | Sally Hall

Bitesized is a mobile application that allows dietitians to remotely support clients. The app promotes more frequent interactions than the typical monthly meeting, and makes it easier to create a more accurate representation of a client’s food intake. From a high level, this is how it works:

How it Works

When creating a new business, it is important to consider your company’s social impact. Core to bitesized’s mission is creating shared value. Shared value refers to policies and operating practices that enhance the competitiveness of a company while simultaneously advancing the economic and social conditions in the communities in which it operates. Bitesized creates shared value where the client, dietitian, and society all benefit.

Unfortunately, shared value receives little emphasis from both the public and private sectors. In fact, both Uber and the Food and Drug Administration miss the mark.

The “Sharing Economy” and Uber
While Uber operates in the “shared” economy space, it acts with selfish motivations. With income as its primary driver, it employs technology without considering the consequences.

In 2014, a hostage situation in Sydney, Australia lead the city to believe that it was under a deadly and coordinated attack. People were afraid for their lives. At the time, Uber implemented surge pricing, causing ride prices to increase by 4x, starting at about $100 to leave the area and get to safety. Uber’s justification was to motivate drivers to risk danger and pick up more people.

Many were outraged, while others argued that the surge pricing was a result of an established algorithm, not a human intervention. However, if Uber truly prioritized the needs of society, it would reconsider how the system reacts in the event of emergency.

Uber once again exhibits its priority on profit, developing its own “driverless” technology — exhibiting little concern for its current employees. As the company moves closer to a world run by Artificial Intelligence, bitesized will emphasize the dietitian’s human intuition. While we plan to gradually integrate AI into our product, we will be careful to enhance the dietitians’ skills, not replace them.

One way we plan to use AI is by allowing a client to automatically log his/her food photo without having to open up the app. The client would take a picture from their lock screen, then the bitesized system would analyze the camera roll and identify photos of food or grocery carts. Shown below is how this might look.

Nutrition Labels and the Health of the American People
The FDA, a guardian of our nation’s health, must also reconsider the perceived value and implementation of nutrition labels. The original purpose of nutrition labels was to help citizens make better decisions around diet choices. Despite the best intentions, it typically takes extensive nutritional education to fully understand the labels.

Bitesized aims to circumvent the complexity of nutrition labels by connecting clients directly to a dietitian. The nutritional expert will provide only the most important information to help the client understand what to eat, without requiring great analysis or interpretation.

Bitesized Shared Value
Where the Uber and the FDA fail, bitesized will succeed. By considering the short and long-term implications of our service, we aim to provide a shared value between clients, dietitians, and society.

Bitesized is a mobile application that allows dietitians to remotely support clients. 

Core to bitesized’s mission is creating shared value. Shared value refers to policies and operating practices that enhance the competitiveness of a company while simultaneously advancing the economic and social conditions in the communities in which it operates. Bitesized creates shared value for the client, dietitian, and for society.

Shared Value for the Client
There is a deep need for dietary support across the United States. There are 27 million Americans who have heart disease and more than 30 million Americans who have diabetes, generating $620 billion in medical expenses each year. These diseases are largely preventable through healthy eating. Unfortunately, diet change is incredibly difficult for a multitude of reasons, including ingrained habits, time constraints, limited financial resources, peer and family influence, and addiction to food itself.

Bitesized helps clients overcome major barriers to diet change by providing the following value: 1) regular and direct connection to a nutritional expert; 2)  easy food logging; 3) inherent reflection and accountability 4) understandable nutritional guidance; 5) incremental change; and 6) a voice in their own food journey.

Regular and remote connection to a nutritional expert
Adopting a healthier diet is easier with a partner on the journey. However, many dietitians only meet with clients once a month, and require in-person meetings. Bitesized provides regular and remote connection to a dietitian, increasing access to the dietitian’s emotional support and practical guidance.


Inherent reflection and accountability
Reflection is key to long-term change — the more mindful the client, the more intention he puts into his actions. The very nature of taking photos promotes reflection and therefore increases the likelihood of behavior modification.

Accountability also plays a powerful role in behavior change — the requirement to share photos with a dietitian will make the client think twice before he makes a decision that will negatively impact his health.


Easy food logging
Recording food intake is quite beneficial — it facilitates self-awareness and can uncover patterns or habits previously unconscious. However, keeping a written food journal or inputting food items into a database can be tedious and time-consuming. Bitesized makes it easy, allowing the client to quickly photograph and share their daily food intake.


Understandable nutritional guidance
The confusing nature of nutrition science can exasperate and paralyze. Instead of asking clients to interpret complicated nutrition labels or count calories, bitesized’s dietitian educates the client with digestible tips, making recommendations based on his current habits.


Incremental change
Small, gradual change is more sustainable than trying to overhaul your diet in one fell swoop. Instead of prescribing a completely new diet or meal plan, the dietitian recommends small changes based on the client’s past and current behavior.


A voice in their own food journey
Instead implementing a “one-size fits all” diet, the dietitian meets the client where they’re at, allowing the client to play an active role in the recommendations and diet changes. Moreover, the client can choose to accept or reject each dietitian suggestion, making him more engaged in his own health.


Shared Value for the Dietitian
Dietitians have deep expertise in nutrition science and powerful intuition around  client need. However, infrequent in-person meetings between the dietitian and the client can stall progress. Moreover, without a full understanding of the client’s daily food intake, the dietitian must resort to general suggestions, as opposed to more powerful, specific recommendations.

Bitesized delivers the following value to the dietitian: 1) better understanding of clients’ food intake; 2) the ability to provide more personal recommendations; 3) the ability to provide consistent communication; and 4) supplemental income.

Better understanding of clients’ food intake
Typically, a dietitian struggles to fully understand what the client eats on a regular basis — even if the client keeps a food log, information regarding portion size can lack accuracy. Bitesized allows the dietitian to get a more comprehensive picture of their clients’ intake.


The ability to provide more personal recommendations
Because the dietitian rarely fully understands the client’s food intake, her dietary recommendations must be more broad than specific, minimizing the potential power of her guidance. By showing the client’s daily consumption, bitesized allows the dietitian to make personally tailored suggestions, more relevant to the client’s current behavior and therefore more directly actionable.

dietitian-personal recommendations

The ability to provide consistent communication, from anywhere
There’s typically a lot of time between a dietitian and client meeting. Bitesized allows the dietitian to support the client on a more regular basis, from anywhere, giving her more opportunities to share expertise and support.

Supplemental income
The dietitian earns money through the bitesized platform, earning $15 per month for each client.

Shared Value for the Client & Dietitian
Bitesized is essentially a private instagram for a dietitian and her clients, but with a much greater purpose.

Social media can be soul-less and draining. It falsely promises connection and love, only to waste your time and sell you more things you don’t need.


Bitesized uses the addictive nature of social media to a constructive end. Instead of mindlessly scrolling, or sharing photos for pure self-promotion, the interactions serve a purpose, building toward lasting, positive change, and cultivating a meaningful relationship between the dietitian and client.


Shared Value for Society

Long-term impact
As illustrated by the walkthrough of bitesized, the long-term impact of the product gaining popularity maps to increased health of the population as a whole. We, previously, discussed the magnitude of the health crisis that we are in the midst of. There are 27 million Americans who have heart disease and more than 30 million Americans who have diabetes, generating $620 billion in medical expenses each year. With systems this large it is difficult for an individual to feel like they have a vantage point from which to see a possibility to create change.

Collective action
When people band together in the name of a change that they see as needed, a collective power is created. Finding common ground about the prevalence of a problem, aside from all bias and perspective, means it is a real problem worth focusing on. Food labels is an excellent example.

Food labels
In the 1960’s food labels began to have more comprehensive characteristics. The FDA said that these food labels were for “special dietary uses,” that is, intended to meet particular dietary needs caused by physical, pathological, or other conditions. Prior to this time, meals were primarily cooked using basic ingredients leaving no real need for nutritional information.

However, as the industrialization of food products continued to take root, consumers requested information that would help them understand the products they were purchasing. The evolution that ensued brought us too far on the metric side of the scale. This is ironic because bitesized takes a stance that doesn’t overload the user with scientific jargon. The goal being people can  comprehensively understand, again, what is good for them and what is not.

As Uber’s political identity (deregulation and a dismantling of the social contract) is said to differ greatly from the service that they provide (facilitating rides from point A to point B), so, bitesized has the potential for a larger purpose. Will bitesized be able to leverage the community of users on the platform to understand what people value and want to know to be able to craft a new nutrition label? Only time will tell.

Either way, design, done right, is collective action. Bitesized studied people to discover how to support them in their desire for a path towards a healthier diet. User’s choosing an unorthodox service like this in place of institutionalized Health Care is collective action.

“If I had asked people what they wanted, they would have said faster horses.” -Henry Ford

Bitesized aims to do the same thing by abstracting people’s needs and giving them the next step that they are passively asking for.

The guide towards a healthier diet: Environmental Impact

Dietitians learn about food, nutrition, anatomy, physiology and how all of those disciplines interact and work together. Therefore they will all guide clients in a similar direction. Whole vegetables, fruits, grains, beans, and lean meats are what any dietitian will tell you to eat. These foods are both good for people and good for the environment. Let me explain with a few examples.


Cheez-its are a highly processed and widely distributed food product. Food production methods aside, I want to explore some of the ramifications of foods like Cheez-its. First of all, the ingredients in Cheez-its need to be distributed to the factories where they are produced (transportation). All of those ingredients then must be run through a series of complicated manufacturing processes to get them ready for consumption (utilities). Next, all Cheez-its must be sealed and ready for a long shelf life (packaging). Lastly, the packages must be distributed to various stores across the country (transportation).

The outcome: A food that is not nutrient dense, contains ingredients that contribute to disease, is inexpensive and environmentally costly.

In the research bitesized conducted to come up with the guiding principles for our product we spoke with a woman named Delilah. One of the things she said to us was,

“When I was diagnosed with diabetes, the doctor told me to eat fish, chicken and turkey. I’m supposed to eat more vegetables… She did not tell me why. I think beef is harder to digest?” -Delilah

Doctors and dietitians steer people, especially those with dietary disease, towards leaner meats. If the trend away from red meats continues this will cut our contribution to global warming significantly.

Red Meat
Cows eat ~6 pounds of grains (corn or soy) per pound of beef produced (resource allocation). Throughout the beef production process it takes ~600-700 gallons of water to produce 1 pound of beef (resource allocation). A cow lets out ~30-50 gallons of methane gas per day (emissions). This is a bigger contributor to greenhouse gases than transportation.

These 2 examples illustrate a higher level look at consumption that our consumerist society doesn’t normally see. And they shouldn’t have to. In terms of food, doing what is best for the individual is also best for our environment so bitesized delivers value that is actionable on the level that matters to the individual.

Carbon Tax
Carbon tax is a service that holds fossil fuel emitters accountable for the CO2 they emit into the atmosphere. imposes a fee on the burning of fossil-based fuels. This serves as a disincentive to motivate a shift towards clean energy. This initiative was created based on the findings that if carbon was taxed and companies had to pay for their impact, many of those companies would no longer be profitable. In this way is there a correlation between carbon and food?

Industrialized foods
Fast food and other highly processed foods are a major perpetrator of the health issues facing the United States population. The revenue from the top 20 fast food companies was 143.8 Billion in 2015. Pepsi and Coca Cola make a little over 100 Billion combined. Comparing this ~250 Billion with the 620 Billion spent on health care for diabetics and those with heart disease we can see a similarity to the carbon tax model.

Should these companies that contribute to dietary disease also pay the price of medical care? Should unsustainable businesses even exist? ~25% of everyone’s tax dollars go towards health care. This means that everyone, including the people making profit at the top of these companies are paying a large amount of money for the impact that is created by unhealthy habits.

Interconnectivity & Humanization
All of this exploration gestures toward the sheer interconnectivity of our world; products, services and systems alike. Any changes touch many other systems that will also be impacted. These downstream effects are, more often than not, more important to consider than the initial creation.

All of these problems exist because we, as a society, have taken a deeper dive into the systematizing of operations with less consideration for the people that would be interacting with the system. Humanization of all of these systems is needed to allow the full value of the system to be experienced.


Conner Drew | Elijah Parker | Sally Hall

Over the past number of months, our team has developed bitesized, a mobile app that enables dietitians to support clients remotely.

Why it matters

Millions of people nationwide suffer from debilitating chronic diseases such as heart disease (30 million), diabetes (27 million), and kidney disease (31 million). The good news? All these diseases can be alleviated or prevented with a healthy diet.

However, diet change can be exceedingly difficult for many reasons including time, price, culture, and ingrained habits. A dietitian can provide invaluable emotional support and practical guidance towards diet change. This support is difficult to maintain considering dietitians only meet with clients once every 1-3 months.

While dietitians gather a general assessment of a client’s diet at each appointment — asking what they ate within the past 24 hours — they’re often unable to get a comprehensive understanding of the client’s daily habits. Therefore dietitians can only provide general tips rather than specific actionable recommendations.

Bitesized allows dietitians to gain a deeper grasp of their clients’ daily food habits, and provide personal, culturally-relevant, and specific recommendations.

How it works

  1. The client and dietitian set goals together, based off the client’s needs.
  2. The client uploads photos of his food intake.
  3. The dietitian comments on photos and makes recommendations based on set goals.

Key Features
Key features include the “bite” journal, chat, and recommendations.

The “bite” journal
The client will upload photos of his meals for the dietitian’s comments.


The system facilitates conversation between the dietitian and the client, allowing the client to ask questions, and the dietitian to make recommendations for diet changes.


The dietitian’s recommendations will show up on the user’s home screen, to serve as a prompt every time the client opens the app.


bitesized Value

The core value of bitesized is to provide a path of incremental change towards a healthier diet by:

Enabling a client’s dietitian to provide regular support from afar. Bite-sized allows dietitians to provide clients with support between visits, providing actionable suggestions. This reminds clients that they are not alone, and that they have a partner in their health journey.

Enabling a client’s dietitian to provide specific dietary suggestions. Bite-sized allows the dietitian to comment directly on the client’s grocery receipt and meals to give clear, specific recommendations. This feature removes the nutritional guesswork and teaches the client why he should eat one item over the other.

Enabling a dietitian to gain a deeper understanding of their client’s food choices, and therefore provide tailored guidance to the client’s distinct needs. While dietitians collect important metrics such as blood pressure, weight, cholesterol, and blood glucose levels, a client’s diet is generally self-reported. By having access to the grocery receipt and meal/snacks, the dietitian gains a clearer picture of their client’s food choices, and therefore can provide tailored guidance, in addition to more general nutrition tips.

Encouraging a dietitian to limit the number of recommendations, supporting a gradual approach to changing someone’s diet. We found in our research that when given a large task such as “eat healthier,” people shut down because of the intimidation around thinking about how far the end goal is away from their current reality. By taking a gradual approach to helping someone improve their diet, we remove this intimidation. Even though a more gradual approach is our recommendation, we will not limit the dietitian and allow them to operate as they see fit.

Capitalizing on existing routines that don’t require significant modification. We believe that if we meet customers “where they are,” we will increase the likelihood of service adoption. Instead of asking our target population to change where they shop or completely overhaul their diet, we will actually make their current grocery shopping habits easier, and slowly implement healthier behavior, week by week, item by item.

Removing unnecessary scientific jargon that only complicates and confuses. Our original inspiration for our product primarily came from low-income individuals who are diabetic. We learned that when someone is first diagnosed with diabetes they are given not only bad news, but also a significant amount of new information for changing their current behavior. This includes a new diet, a new exercise regime, and further responsibility around tracking insulin levels. By removing the complicated jargon presented around food and nutrition, we aim to make it simpler to take action around adopting a healthier diet.

Business Structure and Pricing

Bitesized will be an LLC, charging $30 a month, per user. Half of the fee will go to the dietitian and half to bitesized.

We will “bootstrap” the development of version 1.0 of the app, building it with as minimal funds as possible. We aim to launch the MVP in January 2018.

The limits of our imagination

There’s so much that stifles our imagination — namely, someone’s concept of reality, and what they deem possible within that reality.

I think one of the saddest sentences is “That’s not realistic” — not necessarily the words themselves, but their impact. Certainly dreams for the future should consider limitations, but solely focusing on current constraints is incredibly stifling. More than acknowledging what obstacles lay in front of a particular idea, “that’s not realistic” shuts down creative thinking as to how some far-fetched endeavor may come to be.

I like science fiction for this very reason — it’s not supposed to be realistic, because it’s inherently a part of a different reality, whose rules are entirely up to the author. Moreover, it requires the audience to suspend disbelief, thus allowing them to consider an alternate reality, without the analytical mind interfering with what’s possible.

Fear also plays a powerful role in what we can imagine. How many more articles are there about how singularity will crush humanity than stories of how technology will enhance our capacity to communicate and love?

I believe the more we focus on the dark side of technology, the more we will create a dark future. The longer we can hang on to optimism in our imaginations, the more optimistic our future.

For example, here’s my concept of how we can improve the grocery shopping experience (I never know what I want to eat, and I even if I do, I never know where to find it!).

Screen Shot 2017-04-18 at 7.24.57 PM

Er. Whoops. That got a little dark… but the beginning was nice! I definitely treated myself to some ice cream after that project. You are not the boss of me!

I guess I’m not so immune to imagining the downside of smart tech. Will robots really take over minds? Have they already and we just don’t know it?

Speaking of the Matrix, our teacher, Mr. Anderson exposed us to several different concepts of the future. One of which was illustrated in a talk by Argo design’s Jared Ficklin.

Screen Shot 2017-04-18 at 6.35.25 PM

If you haven’t watched this talk, you must. It tickled me. It details several examples of the kind of design I want to create — provocative, but most importantly, magical.

Mr. Anderson also showed us more bleak concepts, such as Strange Beasts by filmmaker, Magali Barbé.

Screen Shot 2017-04-18 at 6.37.02 PM

Talk about fear limiting imagination — I viewed several different opinions as to how the future could manifest, and my video concept was clearly influenced by this one.

It’s not that I don’t dream of how technology can improve or delight us, but the fact that I chose a more somber tone speaks to my humanity — the human brain is millions of years old (the oldest known hominid, or humanlike species, has been dated at 4.4 million years old). It is not designed to make us happy, it is designed to make us survive. So, it makes sense that the scary would captivate more than the ideal.

Perhaps, more optimistically, technology can help us finally evolve past these old reptilian brains.


The Dark Side of Design: Using Anxiety to Manipulate

Design reflects humanity: it’s wildly complex, and contains at one end, lofty ideals that can better society, and at the other end, dark tools that can manipulate and exploit.

This is why, as designer Mike Monteiro states, “ethics can’t be a side hustle.”

Despite the pull of the dollar, and the seductive nature of power, designers must think about the implications of their designs, and why, as human-centered designers, we need to put the benefit of the human first.

Unfortunately, more often than not, many prioritize the dollar, manipulating consumers by capitalizing on anxiety . 

Capitalizing on the Anxiety of New Mothers: Nestle’s Baby Formula Controversy

The power of money is no better illustrated than through Nestle’s baby formula controversy. In the 1970s, mothers in the U.S. and Europe began choosing breast feeding over baby formula. To make up for losses, Nestle, a major manufacturer of baby formula, aggressively marketed their product to mothers in developing countries, preying on new mothers’ anxiety to do the best for their children.


A 1975 Nestle ad in South Africa

The key issue with this campaign was that baby formula requires clean drinking water, something of short supply in many developing regions. The result was a significant increase in infant deaths due to diarrhea, dehydration, and intestinal infections.

Instead of truly caring about their consumers or understanding their needs, Nestle saw an opportunity to make money, and proceeded with no regard of the consequences.

Events like these prove that Designers must “have a seat at the table,” meaning, they must have a voice in key decisions. Human-Centered Design inherently puts the customer’s needs above all else, which is both good for the person and for the business. After all, your service will ultimately fail if it doesn’t serve the customer’s needs, or worse causes great harm.

However, while I’d love to posit that had designers been a part of Nestle’s process, things would have been different, designers are still human. They are just as vulnerable to the pressure to make money, to “hit those numbers,” and just as susceptible to fear, anxiety, and group think. The very existence of Dark Patterns is a case in point.

Dark Patterns & Attachment Anxiety

Dark Patterns are design strategies to manipulate people into taking an action they don’t originally intend.

One dark pattern is taking advantage of attachment anxiety.

According to Dr. Brian Cugelman, “attachment anxiety is that uneasy feeling you experience when you’re feeling insecure about a relationship… It’s that heightened awareness that you experience, when you sense that someone is threatening your relationships, such as someone making a move on your business contacts, or even more devastating, your social media friends.”

I recently left Facebook (I recommend it!), and like many companies, Facebook uses “attachment anxiety” to keep you from leaving, showing you a list of friends who will “miss you.” (Featured second to the left in the line up is my sweet brother, Joe.)

Screen Shot 2017-03-28 at 6.12.57 PM

This is harmless enough, but an obvious strategy to elicit fear that I will lose love and connection by leaving this virtual community. God forbid that I have to call my brother and actually connect, instead of falsely connecting by mindlessly scrolling through his photos.

While creating anxiety can help a corporation profit, it can also stifle its ability to innovate.

Turning the Tide: Using Design Thinking to Combat Anxiety

Anxiety and the fear of failure are powerful reasons why so many businesses resort to desperate manipulative practices as opposed to entertaining new strategies that actually put the user’s needs first.

When developing new ideas, many look to what worked historically, as opposed to creating the future, regardless of the past.

From the past, we can find data to support our idea, and, as Roger Martin states, “logic plus data provides proof, which generates emotional comfort, which leads directly to commitment.”

On the other hand, “for a new idea, the equation is likely to be: logic without data produces speculation, which results in emotional discomfort.”

Unfortunately, many times, the logic we use to understand the world as it is can keep us from understanding the world as it could be.

Thus, we over-exploit what’s worked in the past and under-explore other opportunities. 

Design Thinking provides a powerful bridge between the known and the unknown, providing a mechanism which creates data while building a new idea.

design thinking

In Design Thinking, an idea results from rigorous ethnographic research, during which the designer gathers data and develops empathy for the people she wants to help. The designer then prototypes that idea and tests it with the user, gathering feedback and continuously iterating, ultimately building data, logic, and emotional comfort, which then rallies commitment to the idea.


The practice of Design Thinking gives designers a framework that generates confidence and provides data towards something new, as opposed to using it for the same old calculating measures. Perhaps, instead of using fear and anxiety, designers can build a new business framework driven by empathy, creativity, and compassion.

As an experiment, I played with the idea of using Facebook to present this material:

Figuring out how to promote a healthy diet, one grocery item at a time

My team and I are developing a service to help someone gradually adopt a healthier diet. First, we will find the cheapest way to buy a shopper’s grocery list, and then, we will gradually suggest healthier substitutions or additions.

Testing our service

To refine the idea, we will recruit shoppers to test our service over the next several weeks. During our first week of the pilot, we plan to follow each participant through the store to learn as much as possible about their shopping habits, decision making, and meal planning.


As the original idea took the form of a mobile app, this exercise will help release our minds from the design of “the screen” and help us focus on the value delivered. Even if the final manifestation is an app, interacting with the participant in-person will allow us to discover the ideal “conversation” to help the shopper receive the maximum benefit.

One drawback of this technique is that our presence may make shoppers more likely to choose the swap offered. Additionally, we will provide $5 HEB gift cards to thank shoppers for their time, which may make shoppers feel obliged to take our recommendations. Results may therefore be skewed. It will be important to lessen our physical presence as quickly as possible in subsequent weeks.


We will target people who go grocery shopping on a regular basis and need help adopting a healthier diet. This means that our recruitment efforts will span across socio-economic status. To quickly screen, we will ask potential participants to send photos of their refrigerator, freezer, and pantry, for a quick assessment of the kinds of food they bring home. 

part0-1 part0-2

If you think about health on a spectrum, from burgers to salad, we’re looking to help people who buy more food towards the burger end of the spectrum.


As we aim for gradual change, we hope to recruit at least 5 participants who will test with us multiple times over the next month. This duration will help us project whether or not our tactics and suggestions will make a positive difference in the long run.


Given our effort to help shoppers save money, we began to look into coupons. After a bit of research, we realized that we must be careful to ensure that we’re actually using coupons to benefit the customer, and not the corporation.


According to Rice University professor, Utpal Dholakia Ph.D, the pitfalls of coupons boil down to four main factors:

  • Regular coupon users pay less attention to the actual price and often end up paying more money.
  • Regular coupon users buy things they don’t need.
  • Regular coupon users buy more than they need.
  • Regular coupon users spend beyond their budget.


Indeed, when we ran the pilot for the first time, our shopper considered taking advantage of the “2 for $6” yogurt sale, but then realized that she could not finish all 8 yogurts before their expiration date.

When we suggest sales, coupons, or lower prices, we must make sure that we’re not distracting our shoppers from a more responsible choice. 

Subject Matter Experts & Nutrition

We know that there are as many different opinions about health & nutrition as there are people in the world. It seems there’s always a new study about why this food may be good for you and that food bad.

Given the complexity of nutrition as a science, we will engage Nutritionists throughout the process to 1) make healthy swap recommendations and 2) frame why one food may be healthier than the other.

When running through our very first test, we saw just how much we needed this expertise. This was particularly clear than on the bread aisle — so many different choices! Moreover, even if we find the “healthiest” bread, our recommendations must also fit the shopper’s taste preference as well as budget.


The Paradox of Choice: Fighting the power of brands & familiarity

The grocery store can be an overwhelming place, which is no wonder why we’ve met so many people who buy the same thing over and over again.

Have you ever actually looked at all the options down the cereal aisle?


There are 12 different kinds of Cheerios, alone: Cheerios, Honey Nut Cheerios, Very Berry Cheerios, Multigrain Cheerios, Apple Cinnamon Cheerios, Honey Nut Cheerios Medley Crunch, Chocolate Cheerios, Fruity Cheerios, Cheerios Protein, Frosted Cheerios, Cheerios + Ancient Grains (?), and Pumpkin Spice Cheerios (so you can be in the holiday spirit, all year long).

Because of the incredible volume and variety of grocery inventory, it’s understandable that a customer’s brand loyalty would be hard to break — why spend time analyzing a sea of options, when your current choice is sufficient? Observations like these also prompt questions like:

  1. Rather than trying to influence a shopper’s cereal choice, would it be better to focus our efforts on change that might occur on an aisle with fewer choices, leaving the shopper with more mental space to consider other options?
  2. Or, if we endeavor to tackle the cereal aisle, would it be best to introduce a new, healthier item before the shopper enters the grocery store, before she becomes too distracted by all the other choices?

The more I learn about grocery shopping, the more I learn about the marketing strategies and business behind it. For example, I had no idea that stores rent out shelving space, and that, depending on the shelf, companies will pay more or less; the most expensive shelving is “the bull’s eye” zone (usually the 2nd and 3rd shelves), as it’s in the customer’s eye line.

In order to help our shoppers, we will have to compete with powerful marketing techniques, and help our customers look above and below for cheaper, and healthier options. A benefit of our service is offering 1-2 healthy alternatives per the shopper’s original, unhealthy choice — still giving the shopper a choice, but not so many that lead to overwhelm.

Capturing Feedback & Results

To capture feedback and results, we will document the shopper’s entire journey through the grocery store via photos, highlighting different decision points.


We will also note the shopper’s path through the store, presenting what other items they might naturally see or pass, and therefore be more open to try in the future.

Lastly, as the shopper goes through the entire process, we will check and update the following assumptions:

  1. People use grocery lists, and if not, they will use one
  2. People will choose a healthier option if prompted
  3. People will choose a lower price over a brand they like
  4. People are willing to leave brands and items they’re used to
  5. People generally want to eat healthier
  6. People will eat new items they purchase
  7. People will be more likely to buy a new item if they get the new item before they get the original item

Measuring Success

To measure success, we will note the following:

  1. How many of the healthy alternatives the shopper accepted and why.
  2. If we were able to save the shopper money, and if so, how much.
  3. If the shopper would like to use our service again.

Other reflections

Keeping our eyes on the prize: Given the fact that coupons, price comparisons, and sales are so immensely complicated, we’ve found ourselves focusing more on how we can help someone save money, than eat healthily. In order to make an impact, we must keep coming back to our core value — helping someone gradually adopt a healthier diet.

Impulse Buys: One question we’ve asked ourselves is how we plan for impulse buys. When surrounded by so many options, it’s only natural for shoppers to pick up items not originally intended. In that instance, how does our service push the healthiest, cheapest option?

Convenience vs. Stick: If we go ahead and pull the healthiest/cheapest grocery items, we believe the shopper will be more likely to adopt those items. On the other hand, giving the shopper a choice, prompting slightly more reflection and initiative, may make the healthier habit more “sticky.”

The Best of Outcomes > The Best of Intentions

Designers have great power to shape the future of humanity, and with that, as Stan Lee would say, comes great responsibility. Therefore, at AC4D, we focus on using design to make a positive social impact. But how do we know if the change we wish to inspire will have the desired effect? Or worse, how do we know it won’t bring negative consequences?

The truth is, even with the best of intentions, we can’t know how our design will affect society until it’s released in reality. At that point, intentions become irrelevant, and outcomes are the only significant measure.

The Best of Intentions: One-Size Fits All

As Michael Hobbes writes in his article “Stop Trying to Save the World,” many well-meaning aid efforts have followed the trend of “exciting new idea, huge impact in one location, influx of donor dollars, quick expansion, failure.”

As a case in point, consider the clean drinking water project, Playpumps. It was an inspired idea — a water system that used the energy created by children playing to operate a water pump. People need water, children need to play, it seemed like a perfect combination. Although initially lauded for its innovation, it was quickly criticized for being too expensive, less effective than traditional hand-pumps, and reliant on child labor.


According to Hobbes, “Many of the villages hadn’t even been asked if they wanted a PlayPump, they just got one, sometimes replacing the handpumps they already had. In one community, adults were paying children to operate the pump.”

Nevertheless, this idea should not be discounted altogether — in some villages, under the right circumstances, they were helpful, and are still installed as a “niche solution” on playgrounds and at schools in poor rural areas.

The real issue was not that Playpumps was a poor idea, but that it was poorly executed.There was little collaboration or research with the people the organization sought to serve, and the implementation was “one-size-fits-all” — based on the fact that since it was an effective solution for some, it could be applied to everyone.

The Worst(?) of Intentions: Corporate Social Responsibility & Cause Marketing

Corporate Social Responsibility
Advocacy is now rivaling sex as Corporate America’s main selling strategy. For example, in response to the Drumpf administration’s travel ban, Airbnb offered free housing to anyone denied entry and Starbucks pledged to hire 10,000 refugees. Seeing this primarily as a marketing tactic, Alex Holder writes that “it’s difficult to separate the fact that while these brands are showcasing pedigree social responsibility, ultimately they’re helping refugees because it sells milky lattes and cheap holiday accommodation.”

In another related example, Lyft donated $1 million to the American Civil Liberties Union after Uber continued to pick up passengers from the JFK Airport amidst a taxi driver strike against the travel ban. Soon after, Lyft bested Uber in the App store for the first time.

While there may be ulterior motives to these corporate actions, the question is… does it matter? Free housing, jobs, million dollar donations… indeed, there is a clear benefit to the companies in terms of public favor and increased revenue, but would we rather do without these grand gestures?

Perhaps it would be stronger ethically for companies to contribute socially, but to do so quietly. But, if not for Lyft’s public donation, Uber may not have pledged to provide legal support and establish a $3 million legal defense fund for threatened drivers.

Cause Marketing
Product(RED) is an organization that recruits companies like the Gap and Apple to participate in cause marketing, donating a portion of product sales to the fight against AIDS. While Product(RED)’s intentions seem pure, some believe that corporate partners only use the charitable association to sell more goods.


Apple donates a portion of its red Beats headphone proceeds to Product(RED). is particularly critical of Product(RED). It rallies people to reject the “ti(red) notion that shopping is a reasonable response to human suffering” and to donate directly to the Global Fund, without consuming.

Yes, we all need to Yes, we’re destroying the environment. Yes, we’re screwed and the rich are moving to Mars… and, if Product(Red) can capitalize on a deeply ingrained behavior, and raise $465 million to help prevent HIV… can we really fault them for it? I’ll make a deal — if they can eradicate consumer culture, I will switch my position and insist that Bono find another way to save the world.

While it’s clear companies have something to gain from their social impact initiatives, their investments and corresponding promotions unquestionably benefit society.

The Worst of Internet: the Rise of Fake News

According to author Mark Manson, the early creators of the internet had good intentions.

“They worked for decades toward a vision of seamlessly networking the world’s people and information. They saw greater empathy and understanding across nations, ethnicities, and lifestyles. They dreamed of a unified and connected global movement with a single shared interest for peace and prosperity.”

Oops. Especially with the rise of fake news, and Facebook’s almost impenetrable echo chambers, we seemed to have missed the mark. 


But then I realize that the internet is a reflection of our society — “echo chambers” have always existed. We love to surround ourselves with like people, it makes us feel safe, secure, and validated. “Fake news” has always been there — the rewriting of history books, or (less severe), those “FW: FW: FW: Obama…” emails from your grandparents — the only difference is it can now travel exponentially faster through the veins of social media.

The good news is that now these very tribal tendencies of pushing out or dismissing the “other,” over perceived differences, are now out in the open. The public outcry against echo chambers and fake news is a call to get curious about the other, to learn about their hopes, their fears, their dreams, and perhaps find some common ground.

In a way, this is a signal for a new iteration of the internet. Designer Jon Kolko says that both the good and the bad are designers’ fault and their ongoing responsibility. I also argue that, as consumers, we have a responsibility to think critically about how we interact with a particular product or service. So, while the initial intentions of the internet did not become what 80s and 90s technologists dreamed it would be, designers and its consumers have a responsibility to create a new version, and keep moving towards the greater vision of peace and understanding.


Sometimes impure motivations can still bring great benefit, and other times, good intentions can bring about the worst of consequences. As designers, the best we can do is diligently research the problem we’re trying to solve, project all the possible implications of our proposed solution, and continue to iterate as the design interacts with the world.

Other Explorations

To explore the complexities of social impact, I created a simple board game that follows the development of a non-profit organization working to increase access to education among low-income individuals in Managua, Nicaragua.

The game requires, at minimum, two teams of two, wherein each team takes turns pulling out cards from the deck. Depending on the outcome of the card, the team would move closer or further away from the finish.

Product Management Part 3: Feature Brief

Over the past two quarters, the class has gone through a process of redesigning AT&T’s mobile application. This process has included:

  1. Brief research to find pain-points within the current app and to uncover what’s most important to the user when managing her mobile account.
  2. Concept modeling to understand the key functionalities of the app.
  3. Ideation to design new flows.
  4. Evaluating, testing, and iterating on those flows.
  5. Estimating how long each design would take to develop.
  6. Creating a product roadmap, detailing how and in what sequence each flow would be built.

Our latest undertaking is the Feature Brief. A Feature Brief is a document that presents a simple, cohesive vision of what you should build and why you should build it. It acts as a north star for the product and its development.

The Feature Brief communicates insights found through research, design pillars inspired by the insights, what value the product will deliver (the value promise), a high-level description of the app’s key features and capabilities, and a roadmap of how a team will build the app.

Through a brief stint of research, I observed the following:

  1. People have an emotional attachment to their phones, acting as an access point to their social networks.
  2. Customer’s usage varies throughout the billing cycle, leaving them wondering if they will exceed their limit.
  3. AT&T offers an overwhelming amount of features and add-ons, distracting the customer from their primary needs.


Design Principles

Based on the above insights, I crafted my design to follow the below principles:

  1. Our product should make customers feel secure that they will always have access to their phones and their usage will never be threatened.
  2. Our product should give customers a clear understanding of their data usage and protect them from overage fees.
  3. Our product should prioritize what customers want to see, and progressively reveal more advanced features as the customer indicates interest.

The Value Promise

The value promise encapsulates the three design principles: Our promise is to give customers complete control and clarity around their mobile phone usage.

Key Features & Capabilities

Our research determined that the following capabilities were most important to customers:

  1. Make a bill payment
  2. Set up autopayment
  3. Manage data usage
  4. Change plan
  5. Upgrade phone
  6. Edit Account Settings

These determined the features & capabilities outlined below.

Product Management Part 2: Product Roadmap

Over the past number of months, we’ve worked to redesign AT&T’s mobile app. This app allows customers to pay their bill, change their plan, manage their data, and upgrade their phone.


After designing the ideal flows, we worked with developers to estimate how long it would take to build each capability. Based off of this information, we created a product roadmap, a horizontal timeline demonstrating how and in what sequence we would create each flow.

Although we designed for an ideal state, without time or financial constraints, the product road map demonstrates how we would ship the app using two developers, releasing a minimum viable product in one month, and two updates released over the following month.

myAT&T Roadmap v3

The road map isn’t meant to track the project hour by hour, or feature by feature. It’s simply to give a general priority and visual timeline for the build out.

Thin Slicing

To fit the first release into one month, we went through a process of “thin slicing.” This means removing capabilities that are not essential to the functionality of the app, while maintaining the app’s core value.

In this instance, we cut out some features within flows, as well as removing whole flows altogether. For example, within the Make a Payment flow, we cut out PayPal and Apple Pay from the minimum viable product and included them in the second release. As paying with a credit card or checking account are available in the first release, these methods were convenient, but not essential.

We also simplified the interaction, exchanging radio buttons and a button for a table. Lastly, we also removed the customized line within the tab bar, as again, it was not essential to the app’s functionality.
Payment 2 Thin Slice Payment 2 Version 1

Whole flows such as Changing your Plan and Upgrading your Phone were also left out of the first release, as, again, they are not core to a customer’s management needs. I will note, however, that although Changing your Plan was not in the first release, we still allowed the customer to control her usage by including the ability to activate “slow mode” (preventing data overage fees), purchase more data for the month, and suspend/deactivate your phone.

For the first release, we prioritized structural components such as the tab bar and the page titles, as well as the following capabilities:

  1. Log in & out
  2. Make a Payment via credit card & checking
  3. Set up Autopay
  4. Data Management: Activate “Slow Mode”
  5. Suspend Device
  6. Get more data for the month

Here is a complete view of the minimum viable product:

The following will be included in the second release:

  3. Change Plan

The third release will include:

Product Management Part 1: Development Estimation

For the past few months, we’ve worked to redesign AT&T’s mobile app. The process has included research, concepting, sketching, and wireframing, evaluation, & iteration. The next step of the process is product development — bringing the app into reality.

Design vs. Product Development

As designers, we are user-centered; we focus on people, their goals, and the way the design will support their experience in achieving those goals. Design is all about visualizing an ideal state and sketching our way to that future.

Once we get into production, however, we must also be technology-centered. “Shipping,” or product development requires the product manager to be pragmatic as she brings the product to market.

While the design process is all about the user’s behavior and feelings, product management zeroes in on the system’s components, features, and controls.


The first step to shipping is consulting with a developer. While designers love to play in ambiguity, developers tend towards “well-defined” problems, strive for efficiency, hate to do the same work twice, and guard their time.

Although these two mental frameworks may seem antithetical, it helps the designer move from “blue sky” to “realistic,” consider reusable components (leading to efficiencies), and get ready for sizing.


Sizing is a method for assigning relative time estimates to build unique features, components, and controls. Sizing helps guide priorities, identify total time on task for a development effort, and steer redesign efforts to quickly launch the product.

Sizing, despite being often being wildly inaccurate, 1) provides clarity to stakeholders who have to commit to delivery (to a board of directors, for example); 2) provides clarity to marketers, who need to build campaigns around delivery dates to understand an order of magnitude for producing a product; 3) gives the entire team a view of the product, so they understand it thoroughly; and 4) forces detailed interactions between the designers and developers.

Sizing Method

To size my wireframes, I walked my developer through my flows, and he estimated how long it would take him to create each component, screen by screen. He gave his calculations in “man days” (a man day being equal to one day of work for one person), and estimates ranged anywhere between a half day to 3 days. 

Then, I asked my developer to estimate how long it would take two developers to create each flow. To my surprise, instead of simply halving his calculations, he divided them by 1.5, to account for sick days, inefficiencies, or unforeseen roadblocks.

As, again, sizing is often inaccurate, I then took his calculations and added a 30% padding to each, a common practice among product managers. You can see calculations illustrated below, as well as in this spreadsheet: myAT&T redesign estimation – Sally 

Login & Homescreen

Autopay Change Password   Upgrade Phone Part 1 Upgrade Phone Part 2

As of the latest calculations, production would take 51.5 man days. The next challenge will be updating the design to only require the allotted 40 man days. Stay tuned for Part 2: Thin Slicing & Road Mapping.

myAT&T Mobile App Redesign: Evaluation

Last quarter, we went through a process of redesigning the myAT&T app. Although smartphones have become more and more important to our everyday lives, actually managing your mobile phone account has remained frustrating and confusing.

The Design Process

Before we started designing, we sought to understand the key purpose of the app. To do so, we surveyed about 20 people to assess what was most important to them when managing their account.

We found that the user wants to:

  • feel like she has the right data plan for her needs, that she doesn’t have too much data (so she’s paying for data that she’s not even using), or too little (so she gets hit with data overage fees);
  • be able to easily upgrade her phone; and
  • never miss a bill payment.

Given this understanding, we decided to design for the following flows 1) managing data, 2) changing your plan, 3) upgrading your phone, 4) paying your bill, 5) setting up autopay, and 6) managing the security settings of your account (e.g. changing your password or updating your email address).


Once we completed our designs, the next step was to evaluate our work. This process included three standard evaluations:

  1. The Cognitive Walkthrough
  2. Heuristic Evaluation
  3. Think Aloud Testing

The Cognitive Walkthrough

Developed in the 1990’s, the Cognitive Walkthrough is a method for evaluating the learnability of a product, based on a theory of problem solving in unfamiliar situations.

When confronted with a unique, new situation, people leverage a problem solving theory based on exploration and progressive behavior refinement, generally with the following steps:

  1. We determine what controls are available for us to take action.
  2. We select the control that makes the most sense towards incremental progress.
  3. We perform the action using the control.
  4. We evaluate the results of our action to see if we have made positive, negative, or neutral progress.

The evaluation is based off these steps, requiring the evaluator to ask the following questions:

  1. Will the user try to achieve the right effect? The user of the system has an end goal in mind, but needs to accomplish various tasks to complete it. Will they even know to perform the specific steps along the way?
  2. Will the user notice that the correct action is available? Is the option visible and on the screen, or at least in a place the user will likely look?
  3. Will the user associate the correct action with the effect that user is trying to achieve? Is a label or icon worded in a way that the user expects?
  4. If the correct action is performed, will the user see that progress is being made towards their goal? Is there any feedback showing that the user selected the right option or is making forward momentum?

Heuristic Evaluation

The Heuristic Evaluation involves comparing an interface to an established list of heuristics – best practices – to identify usability problems.

This evaluation was established by a man name Jakob Nielsen in the 1990’s. Although technology has transformed dramatically since then, these heuristics are based on human behavior, and still apply today.

They include:

  1. Visibility of system status. The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.
  2. Match between system and the real world. The system should speak the users’ language, with words, phrases, and concepts familiar to the user, rather than system-oriented terms.
  3. User control and freedom. Users often choose system functions by mistake and will need a clearly marked ‘emergency exit’ to leave the unwanted state without having to go through an extended dialogue. Essentially, the design should support undo and redo.
  4. Consistency and standards. Users should not have to wonder whether different words, situations, or actions mean the same thing. The design should follow software/hardware platform conventions.
  5. Error prevention. Even better than good error messages is a careful design which prevents a problem from occurring in the first place.
  6. Recognition rather than recall. Make objects, actions and options visible. The user should not have to remember information from one part of the dialogue to another.
  7. Flexibility and efficiency of use. Accelerators – unseen by the novice user – may often speed up the interaction for the expert user to such an extent that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions retrievable whenever appropriate.
  8. Aesthetic and minimalist design. Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
  9. Help users recognize, diagnose and recover from errors. Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
  10. Help and documentation. Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.

Think Aloud Testing

Think Aloud Testing evaluates the usability of your work by encouraging a user to think out loud as they use your product or service.

It is important that the user does not reflect on why they do what they do, but simply talk aloud as they do it. Reflection uses a different part of the brain, and any introspection would not speak to the intuitive measure of the design.

As the user tests the product, the designer pays particular attention to any communication of surprise, frustration, or design suggestions; she also notes, of course, if the user is unable to complete the task with ease or at all.

Benefits of using all three evaluations

While all three tests stand on their own, there is great benefit to using all three together. For example:

  • Think Aloud participants may have trouble articulating why something was confusing or frustrating; Heuristic Evaluation and Cognitive Walkthrough can provide hypotheses
  • Heuristic Evaluation and Cognitive Walkthrough can help the designer know what to look for during Think Aloud
  • While view to view, Cognitive Walkthrough may assess the flow as seamless, the Heuristic Evaluation and Think Aloud help the designer see the design as a whole — i.e. although something may theoretically work within one flow or screen, it may confuse the user, if it is not consistent with other flows or accepted practices

Key Findings

By taking my app redesigns through these evaluations, we found the following key issues:

  1. Design did not always give a clear sense of place
  2. Intention of screen was sometimes convoluted
  3. Design did not help prioritize action

Design did not always give a clear sense of place

A glaring example of how the original designs did not give a sense of place was in the flow from “Home” to “Set up bill payment.”

MyAT&T Evaluations 2017-01-18.002

When the user taps on the “Set up bill payment” button, not only does a modal pop up, but they are also immediately taken to the Billing tab. This is a violation of the Heuristic principal of Consistency & Standards. Typically, when a modal pops up, the rest of the system stays in the same place. However, in this case, the app takes the user to a completely different place in the system, and there is no clear sense of what would happen if the user tapped on the “x” of the modal — would she be taken to the Billing home screen, or back to the Home screen?

MyAT&T Evaluations 2017-01-18.003

Based of this this evaluation, I changed the flow to from the Home screen, to Billing, to Set up Bill Payment; and I removed the Set up Bill Payment flow from the modal.

MyAT&T Evaluations 2017-01-18.004 MyAT&T Evaluations 2017-01-18.005 MyAT&T Evaluations 2017-01-18.006


Intention of screen was sometimes convoluted

The original Home screen provided a strong example of a convoluted design. Most important to the user is that she isn’t paying too much for data. In the original Home screen, there is an alert that the user is at risk for exceeding her data limit, but, because the data and billing cycle are separate on the screen, it’s hard to gauge the seriousness of the risk.

MyAT&T Evaluations 2017-01-18.008

To address this issue, I merged the data and billing cycle into one visual.

MyAT&T Evaluations 2017-01-18.009


Design did not help prioritize action

Throughout the design, we found many examples of no clear system prioritization — for many of the flows, the user would need to think carefully about each choice, as opposed to being guided by the system.

For example, if the user wanted to manage her data, the system gave her five different options, with no explanation of what each option might provide, nor any prioritization of what might be the best choice.

MyAT&T Evaluations 2017-01-18.014

MyAT&T Evaluations 2017-01-18.012

To address these issues, I updated the flow to only include three options, with an explanation for each.
