Information Architecture

After research on existing online food order apps, these were the main essential features that would meet user needs.

Low Fidelity

Based on the information architecture, I developed rough sketches of the wireframes and the user flows from one screen to another.

Usability test documentation

The usability test was conducted with 5 participants at ISU Student Innovation Center. The participant's ages range between 20-27. The average experience level of using smartphones, tablets, and computers is high. They were required to complete the task list provided by me.

Data collection

After five user testing, I replayed the recordings to record the time spent on each tasks, and number of errors clicked in order to get to the task. The datas collected gave me an understanding of whether the features and navigations of my app were clear or confusing. The table below shows one of the participants data using Google excel sheet. The average time to complete all the tasks was 15 minutes.
