Food Truck App

A new app to order lunch that allow customers to pre-order, complete payment online and go to location to pick it up.

The Project

Understanding the user

Research goals: Figure out if the new app will have a positive impact for customers.

We had the following key questions to answer:

  1. How long will it take for users to complete an order?

  2. How can we improve our order system?

  3. Do we have any issues with the payment system?

● Six participants completed an order on their own. After completion they answered a questionnaire.

● It was an unmoderated usability study.

● KPIs: time on task, user error rates and system usability scale (SUS)

User research:

Pain points

1. Schedule
2. Menu
3. Descriptions
4. Clarity

Starting the design

Paper wireframes

We started our iteration process by creating paper wireframes.  Prioritizing the creation of a simple and smooth ordering process.

Digital wireframes

During the first phase of the design we set a few items that would be constant and the basis of our app.

Low-fidelity prototype

The low-fidelity prototype demonstrated the entire user flow.

Usability study: findings

We conducted a usability study in order to refine our design and start our high-fidelity prototype.

Round 1 findings:

1. We need a better way to categorize menu items
2. We need improvements in our schedule for pickup times
3. We need better clarity and accessibility

Round 2 findings:

1. We need better confirmation after completion of orders
2. We need better navigation

Refining the design

High-fidelity prototype

After our improvements and changes we had a better and more accessible app.

Accessibility considerations

1. Implemented sufficient colour contrast
2. Used simple icons and images
3. Provided alternative navigation and menu access in all pages
