Case study: delivery app feature

Concept of a new feature for Lieferando that is offering the possibility to deliver food in a sustainable way, so no waste is produced.


Year 2020 brought many changes into our life. Many business models started to change into new forms. One of these is the food and service field. Restaurants and coffee places went online and food delivery services increased.

Problem statement

How might we help a person that orders online to choose delivery in a sustainable way.

By reshaping the same problem from our user perspective:


As I had to create a completely new feature that is not existing in a market yet I started straight away with analyzing the structure of the Lieferando app.

User flow

Mid fidelity prototype

In order to understand better how integration of a new feature might work and to test it with real users I created basic user flow in a mid fidelity prototype.

Feature integration

After testing the mid fidelity prototype, in a process of creating a high fidelity prototype I took into consideration some feedback from users and small visual corrections were made. The goal was also to recreate the style of the app as accurately as possible and implement new information so that it matches the look and feel of the whole app.

In this project for me it was important to see the whole mechanism behind one app. How it works, which information is main and which one is secondary. It helps me to decide to integrate the feature not as a separate icon/button, but integrate it natively into app structure.
