Tit for Tat

Tit for tat is a mobile app + responsive website that enables Parsons students to exchange second-hand goods with each other. I was responsible for the entire project, from research to final prototypes. This project was awarded the 2017 Core 77 Design Awards in the visual communication design category. “Tit for Tat”.

 

The Problem

The Problem

One of the biggest costs university students have to worry about are class materials. This goes beyond just expensive books at a design school like Parsons, in which students also assume the cost of materials like materials fabrics, painting supplies and speciality papers, etc.

 Not only is the problem that the materials are expensive, but a lot of waste is produced because after single-use after a class is over, these expensive materials just sit in storage collecting dust.  I experienced this problem first-hand when I tried to sell some of my class materials, and ran into two primary problems:  1) Finding trustworthy people to sell to    2) Getting a fair price  Because I existing second hand goods market had some problems like 1) and 2) above, I landed on the idea of bartering in school.  My observations led me to realize that students could find value in an alternative platform that allows for EXCHANGE of used class materials based on barter, not money.  I found that this presented dual opportunity: save money and protect the environment by reducing waste by exchanging used materials.  I also found a solution for problem 1), finding trustworthy people to sell to. Tit for Tat helps with this trust factor when it’s all within Parsons students. This solution would be more optimal than trusting complete strangers when exchanging your goods. This also helps with identifying the right products for the classes (microcosm of school students only) and expectation of trust amongst people in a smaller circle. It would make communication easier.  Thus began my user research.

User Research

User Research

In my research, I found some existing approaches to the problem. First, there were Facebook groups set up by students for students group page. The page had postings of events, buying & selling materials and jobs.

The problem was that there was a lot of noise in the buying & selling marketplace: not only were there several student groups, but the Facebook groups were not optimized for efficient exchange. However, there was enough activity in these unofficial Facebook groups to validate the problem of buying & selling class materials.

 I also conducted competitive research with 3 of the most similar platforms: Offer Up, Let Go and eBay.

Storyboard + Userflow

Storyboard + Userflow

To get a better sense of the most common user journey, I illustrated storyboards based on user research and the personas I created. This is one of those common user journeys:

User Flow

User Flow

Based on a combination of competitive research and going through the process, I defined 4 main tasks for user flows. 

Initial Designs, Wireframes, Prototypes
