PROJECT REVIEW
Solidaridad Latam is an international NGO that helps small commodity producers in developing countries.
Problem
In this context, I was tasked with designing an app to help small miners improve the negotiation of mineral prices.
Solution
Based on previous client research, it was determined that an auction system would help broaden the quantity and quality of proposals.
My Role
Information architecture.
Interaction design.
Usability testing.
SCOPE
I joined a team consisting of the client, a business consultant, and a UX researcher who provided insights gathered from their research.
Information Architecture
To simplify the process, I integrated wireframes with the user flow. The graphic below illustrates the interaction between the three user roles: miner, mineral-buying plant, and the app administrator.
UI
I designed minimalist interfaces with linear navigation, featuring a prominent 'next' button, considering a significant percentage of users with older age, vision problems, small screens, and low digital literacy.
It wasn't relevant to create a low-fidelity prototype, style guide, or even a design system because the project had an exploratory nature, and the delivery deadline was short.
PROTOTIPO
Usability testing
I conducted in-person usability tests using the Maze tool to record interactions and analyze them afterward. Based on the results, we made changes that resulted in clarifying the process, the text, and simplifying the interfaces.
Results
In 100% of the cases, the testers successfully completed the tasks. Between the first and second round of tests, we managed to reduce the rate of incorrect clicks from 40% to 18% for the "accept quote" task and the time taken for the "request a quote" task decreased from 124 seconds to 103 seconds.
Client feedback
The client was quite satisfied because I was very punctual in every meeting and delivery. Also, there was very good communication with the entire team.
