Cafeteria website case study

The goal: 

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

Project duration:

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 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 can order a coffee from his place in cafeteria.
