The product

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

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.

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

Pickup
Not picked up in time and coffee could be cold.
Ordering in place
Why using app in cafeteria to ordering a coffee?
Accessibility
Missing assistive technologies
