Cafeteria mobile app case study
Case study: Part of my Google UX Design Professional Certificate program.
2022
Project overview
The product:
The application is for a better experience in the cafeteria and should help people order coffee.
My role:
UX researcher, UX designer, UI designer
The problem:
People don’t want to lose their seats based on their orders. Sometimes, people want to sit and order from their place to keep their place in the cafeteria.
Responsibilities:
user research, wireframing, prototyping, designing
The goal:
Create an app that will allow you to browse the menu, create an order, and select a table in the cafeteria.
Project duration:
September 2022 – December 2022
Understanding the user
User research: Summary
I conducted user interviews and created empathy maps to understand the users. A primary user group identified through user research was working adults in the office who want to enjoy coffee.
This user group revealed problems like delivery/pickup – coffee could be cold, and some customers want to sit and enjoy the coffee.
User research: Pain points
1.
Pickup
Not picked up in time, and the coffee could be cold.
2.
Ordering in place
Why use an app in the cafeteria to order a coffee?
3.
Accessibility
Missing assistive technologies.
Persona: Tom
User journey map
Mapping Tom’s user journey revealed how he could order a coffee from his place in the cafeteria.
Problem statement

Low-fidelity prototype with ordering scenario is available here:
Usability study: Findings
Round 1 findings
1. Users want more languages
2. Users want to order more types of coffee
3. The user wants more information about the picking table
Round 2 findings
1. Missing information about the table in the summary
2. Missing table information in the summary page
Refining the design
Mockups
High-fidelity prototype
The final high-fidelity prototype is done and available on this link:
Accessibility considerations
1
Users want more information about the table. I used images of what the table looks like and added more descriptions about the place.
2
Users want information about the picked table on the summary page. I added this information to the overview.
Going forward
Takeaways
Impact:
The number of downloads is double what we expected.
What I learned:
I learned that doing a usability study multiple times is very useful.
