The Task

In 2016 I applied for a job at a very well known design company based in Munich with offices all over the world. To prove my design skills I needed to fulfill this design task with 2-3 days, which I did. Afterwards I was invited into the Munich office and did a very successful presentation, which resulted in a job offer. At that time I was also applying for the job at caresyntax and in the end I decided to stay in Berlin.

The process

The goal of this task was to showcase how I would approach this project and what steps I would go through. So I focussed on the research and ideation part of my design process.


In the research phase I need to gain information about the client, the customer and the context.

There are different methods to get information from the client, customer and about context.

In the context of this case study I actually did some interviews with colleagues from Wooga, where I worked at that time.

Besides the interviews I also observed the way users get their coffee from a coffee machine. The biggest pain point was, that users had to change the coffee settings very often, because the machine was also used by other colleagues.


Based on my research I collected lots of ideas for my coffee machine Concept.

The next steps were to discuss the ideas with the client, to get feedback from customers and based on that to iterate on the feedback.

Interaction design

In the next phase I created simple wireframes to showcase the user flow of my concept.




The next steps were to discuss the ideas with the client, to test the ideas with prototypes and to iterate based on the feedback from the tests.

Visual design

Before starting with the visual design, we need to ask ourselves, who we design for. We need to consider the client/brand, the customers and the context.
