Waste smart

Project Overview

Each year, 108 billion pounds of food is wasted in the United States. That equates to 130 billion meals and more than $408 billion in food thrown away. Every day most of us might experience some food waste and face questions. Which ones are going to get worse or have gone spoiled? How can I reduce food waste? So, we decided to design an app to help users track the perishables in their kitchen to have less food waste, providing recipe suggestions using the items already available in the kitchen.

Phase 1: Research

We want to extract information from users to understand their experience of food waste and the real problem and typical behavior of their particular situation. Therefore, in-depth user interviews were conducted with six potential users, and an online survey on how they reduce the amount of food that spoils in a household, how much and how often users throw away spoiled food, what level of interest users have in reducing the food waste, and what are their motivations.

Online Survey

A total of 36 individuals took part in the survey where the target audience was people who cook at home. Survey questions included questions about the experience of food wastage in the last 2 weeks and the way to track the food in the kitchen.

6 One-to-One Interviews

Affinity Diagrams

After researching, we created affinity diagrams to organize many ideas into their natural relationships from user interview data. Then we created an empathy map to understand users’ feelings, thoughts, and experiences.

User Persona

Phase 2: Definition & Ideation

We analyzed the data and brainstorm the solutions using the I Like, I Wish, What If method and Feature Prioritization Matrix in order to define problems in an attempt to identify strategies and solutions that might not be instantly apparent with our initial level of understanding. We tried to tackle problems, creating many ideas in brainstorming sessions to solve the major problems users were facing.

Hypothesis Statement

If users had an easy way to track the perishables in their kitchen, they would be able to save money and reduce waste.

Users Insights

A waste-conscious home cook who feels guilty about food waste needs to use all the food in their home before expiring but can’t keep track of the expiration dates.

Feature Prioritization Matrix

Features to be focused
Throughout discussion with the team, we cut down a long list of high-impact and low-complexity ideas and narrowed it down to 5 features vital to solving users’ problems. They would help users reduce food waste and easily save money.

  • Suggestions on what to do with food items that are about to expire or have already expired.
  • Push or in-app notifications
  • Recipe page
  • Add items to the inventory using a barcode or a grocery receipt to bulk upload
  • Share with household members

Storyboard

User Flow

This user flowchart shows how users travel through the Waste Smart app while performing a series of actions to achieve goals; reducing food waste and saving money by using about-to-expire items, tracking food inventory in the kitchen.

Competitor Analysis

We wanted to learn how other apps were trying to solve these problems. After analyzing the existing products, we found that most apps need to provide information on preventing food waste.

Nowaste

Popular, clean UI, positive reinforcement, expiration notifications, requires paid membership, does not provide information on how to prevent food waste

Fridgely

Clean UI, no expiration notifications, does not provide information on how to prevent food waste

Grocery

Works fine as a shopping list, with confusing UI,  no expiration tracking, sneaks ads into lists

Phase 3: Prototyping

Low-Fidelity Sketches

Once we know what features our solution should have, we started our low-fidelity prototype with paper sketches.

Visual Elements

High-Fidelity Prototype

1. Home screen

Get notifications on items about to expire and fresh in each space that can be customized.

2. Add items

Users can add items to the inventory using a barcode or a grocery receipt to bulk upload and type in manually.

3. Recipes and other ways to use items about to expire

Once users get a notification on items about to expire, they can explore the recipe suggestions by the availability of ingredients in their pantry or fridge, and another alternative way to use the items. Also, users can save and organize their favorite recipes to access them anytime.

4. Profile screen

Users can easily add another household member in order to share the shopping list, inventory status, and recipes.

Phase 4: Test

We added most features and functionality that users need, but it would be necessary to elaborate on usability tests to see how users feel about the app.

Usability Testing

We facilitated usability testing sessions with five different people. Each participant was asked to complete five tasks using the prototype, so we could observe how well they could use the app to reach their goals.
  • TASK 1: Show me how you would add an item to your kitchen using the barcode feature.
  • TASK 2: Tell me which recipes you could make with the items in your kitchen.
  • TASK 3: Find ways to use an about-to-expire item in your kitchen.
  • TASK 4: Invite a family member to use Waste Smart.
  • TASK 5: Browse Waste Smart.

Feedback

Iteration

The majority of our users were able to complete the tasks. They did have some questions along the way and pointed out areas for improvement.
Conclusion

Solution-based approach to solving user's problem

During the design thinking process, I tried to seek to understand users, their challenges, and problems and create ideas for innovative solutions, as well as a collection of hands-on methods. Once I investigated the conditions of the issues, it helped me brainstorm all ideas for improving the product and solutions so that users could have some available options for each problem. Waste Smart will let users reduce food waste and save money by efficiently tracking food’s expiration dates and having recipe suggestions or alternative ways to use expiring items.
