Problem

Food waste impacts the environment. Although, the majority of people consider food as biodegradable, and a common misconception exists that if one person wastes, it won’t impact the environment as much but in reality, the impact is big as it accumulates. Food waste not only impacts the environment but also society as well.

How might we help people to manage their food inventory at home and thereby reduce food wastage at home?

Solution

A mobile application that provides real-time updates on the quality of food inventory at home through smart tags and suggests efficient utilization mechanisms.

Design Process

The design process followed was: empathize - define - ideate - prototype - test. The approach taken at each stage depended on the goal and what was required at that stage.

SECONDARY RESEARCH

Understanding the scenario

Literary reviews were conducted to understand how food waste impacts various facets of the world, why it is happening and where is it prominent and what are the current solutions in the market.

Impact/Environment

1/3rd
of all food produced around the world is wasted.
30-40%
food of the entire US Food supply is wasted.
11%
of the world’s greenhouse gas emissions is due to food waste.

Impact/Society

35 million
people across America have food insecurity.
$1600/year                         =
money wasted by Americans each year on food waste.

Impact/Home

Our food waste come from
TARGET AUDIENCE

For whom?

Based on the research conducted, the target audience was finalized. The solution shall be for Indian elders above 75 with limited knowledge of digital devices.

survey

Understanding & defining the customer base

To understand the customer base, their awareness, shopping, storage and wastage patterns, a survey was conducted. It received 38 responses. We understood that, contrary to our belief, the problem affects people from all age groups.

A quote that hit us most was

"I literally hate it so fucking much and want to cry every time I throw something away that gets wasted. There is a lot of guilt involved with it for me so I’m using that more now as motivation to change."
User interview & Observation

Getting into depth

We conducted user interviews (questions) of 8 people with diverse backgrounds (students & working professionals) and age group to understand their viewpoints and current food inventory management mechanisms. Following that, observations were conducted at homes, and grocery stores to see their storage habits and supplement the former research.

We found that people end up buying more than what they want and get busy with lives that they forget about the items.

Affinity Diagram & KEY INSIGHTS

What was uncovered...

Affinity diagram was used to make sense of all the data by identifying themes.

Some of the common reasons identified for food wastage at home are:

Busy Schedules

Customers need to quickly prepare food for required proportion based on what is left in fridge and its shelf life without any stress.

Forgetfulness

Due to their busy schedules, customers often tend to forget to check upon their food inventory at home, leading to spoilage of them.

Improper Planning & Storage

Customers tend to buy more than  required due to several factors and struggle to store food properly and consume within the required time.

One of our major insights was that we believed the issue will exist for the younger population we uncovered that it could affect any age group either due to improper planning, busy schedules, excessive buying behavior or forgetfulness.

ARCHETYPES

This is for...

Based on the insights, archetypes were created based on the customer’s awareness on the impact and the readiness to act upon. The project primarily focuses on the Essentialists and the Enthusiasts as they are willing to adopt new technology.

Hero
“I hate it because of the environmental impacts and the lack of food in other countries"
Ally
“I always try to never waste food as it is a lot of expenses, and time consuming"
Trickster
"I work long hours, and take care of my family. Being mindful of food is time consuming."
Ignorant
"Vegetables and food in general here are very cheap, so I don't mind if it goes bad"
FINALIZING GOAL

Which direction?

Reduce
43% of food wastage happens at home. It happens due to improper storage, excessive buying, and lack of visibility in the refrigerator due to stocking up the food in it.
Reuse
0.5 percent of the US population in the US are food insecure. There exists a big gap in efficiently utilizing the food that is getting wasted and people who need food.
Recycle
There are different ways to compost food waste. However, very few people recycle their food waste due to lack of knowledge and support along with varying law regulations.

Ideate

IDEATION & BRAINSTORMING

Exploring Ideas

‍How might we help users to manage food inventory and reduce the food wasted at home?
How might we help the users to effectively reuse the leftover food at home?
How might we help the users to recycle the food waste at home in order to help the environment?

Based on the statements, 2 ideation sessions (with the team & with the target audience) were conducted. Further, the final idea was selected through several internal discussions and votings based on desirability, viability, and feasibility.

Design

IDEA

The smarter way to managing food inventory

Following the brainstorming session, 3 ideas were finally shortlisted and validated against their desirability, viability, and feasibility. 2 solutions focused on donating food items and encouraging recycling food. The 3rd and final solution is to reduce food wastage at home and effectively utilizing it.

A smart tag + mobile app ecosystem that monitors & notifies you to utilize the food inventory efficiently

Value Proposition

How it works?

Every food releases gasses during its oxidation process and chemical sensors sense these gases (Reference). Based on it, the food expiration date can be predicted, and users can be notified via the app through near-field communication.

design explorations & iterations

Wireframes

Once the idea and layout was finalized, various variations of the idea were explored and the best ones were combined to form the final wireframes.

USABILITY TESTING

What can be improved?

Think-aloud sessions were conducted for the application with 8 participants. 4 tasks were provided to the participants to perform:
1. Connect food item to a tag
2. Track the added food item
3. Identify how to use it through recipes
4. Remove the food item

1. Progressive Onboarding
New onboarding helps users' to understand how the app works and how to use the sensor to connect food items

“But I have a tag and a food item, how should I proceed?"

2. Better visual cue & matching mental modelThe interactions that are unconventional were changed to the interactions that matches user's mental model.

"This way of deleting food item is very hard and takes much time to figure it out"

2. Improved UX copy‍The UX copy was improved and updated to remove any confusions to the user and convey the accurate message.

"Does 0 days means, it's expiring today?"

Anticipated Challenges

“But how will I connect the app with my dad's watch?" - Caregiver

Solution: A step-by-step tutorial during onboarding and under menu section.

“I am a bit skeptical on the solution as most of us don't know how to use this?" - Elder

Solution: The app uses other capabilities of smart watch to evaluate a user's mental state such as stress levels. Therefor, the app can also work with no user intervention as well.

VISUAL DESIGN

An app for comfort and support...

The mood board leans into the feeling of comfort, calm, reflection and mental stimulation. Elders are encouraged to explore and reflect on their emotions through the minimal patterns.

Reflections & Learnings

Reflections

We learnt, laughed & argued (healthy, ofc) a lot

1. Having healthy arguments
There were instances where we didn't agree to each other's points. I learnt that the key is to listen patiently, take time, ask questions and understand their viewpoint and explain your viewpoint and finally weigh both.
2. Listen to your team
While working on a team, it is very essential to listen to what everyone says and to ensure they are included. After 8 weeks, I can proudly say I have got not only a solid team, but good friends.
