The product: 

Application is for better experience in cafeteria and should help people to order coffee.​​​​​​​

Project duration:

The problem: 

People don’t want to lose their seats based on their order. In some cases people want to sit and order from their place to keep this place in the cafeteria.

The goal: 

Create app that will allow to browse menu, create an order and select the table in the cafeteria.

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, some of customers want to sit and enjoy the coffee in place

User research: pain points



Not picked up in time and coffee could be cold.


Ordering in place

Why using app in cafeteria to ordering a coffee?



Missing assistive technologies

Usability study: findings

Round 1 findings

Round 2 findings​​​​​​​

1.  Missing information about table in summary

2.  Missing table information in the summary page

Refining the design


High-fidelity prototype

Accessibility considerations


Users want more information about table. I used images how the table looks like and I added more description about the place.


Users want information about picked table in the summary page. I added this information to the overview.

Going forward



Number of downloads are doubled than we expected. 

What I learned:

I learned that doing a usability study multiple times is very useful.
