DURATION : 4 days                                ROLE : Research, user research, prototyping                                TEAM : Individual Project

The aim of this project was to test the so-called "sprint" method. I then thought about a problem in everyday life: that we have never experienced this situation: we open our fridge and we realise that we forgot to eat this vegetable and we find ourselves throwing it away. So I asked myself:

ANALYSIS

First of all, I had to find my target, so I launched a survey in order to understand who throws away the most, what they throw away the most, why and how they consume.

While waiting for the answers, I brainstormed about what waste means to me and did some research on the Internet.

I then analysed the answers (32). The result was that :

 • The leftovers are the ones that are thrown away the most.
 • They waste because they forget the food in their fridge.
 • They pay attention to expiration dates when they buy

Contrary to the others, couples between 25 and 49 y.o don't make a shopping list. They are the ones who waste the most.

Knowing this, I decided to focus on couples between 25 and 49 y.o and interview them in order to understand:

• Why are they more prone to waste?
• Understand the user's path from the moment they go to the grocery store to the moment they throw away
• Understand the user's state of mind during the main steps

I quickly realised that, contrary to the data in the survey, couples were careful about wasting because of lack of money and planned what they were going to eat.

I knew that families also tended to waste a lot thanks to the survey, so I asked them to tell me how it worked in their families.

I then interviewed some families and my hypothesis was confirmed:

• They tend to waste leftovers every week.
• They make a shopping list but they let themselves be guided through the shelves.
• They often make too much food.

So I asked myself why do families who know everyone's tastes and eating habits spoil so much?

I realised that it was impossible for them to predict the desires and appetite of each family member. In addition, they eat together: leftovers are eaten alone at lunchtime at work: after 2 days they don't want to eat them anymore because they are tired of eating the same dish. These leftovers end up forgotten in the fridge and thrown away.

IDEATION

An application to put neighbours in touch with each other so that they can either sell their leftovers, or exchange them so that everyone can enjoy eating and reduce waste.

DEVELOPMENT

First of all I made a usage scenario for the seller and for the buyer with the different possible paths.

I quickly did user testing sessions. I first wrote 3 scenarios to make the user more autonomous but also to make sure that I could see every possible interaction.

Following user testing sessions I modified the previous wireframe by implementing user feedback.

I discovered the sprint method through this project and I loved it. I find that it's a way to quickly find its users and quickly understand from where comes the problem and whether there is indeed one. Despite the "mistake" in the target, I am proud to have been able to get back on my feet and quickly redirect the interviews to identify the best target.
