Designthinking project


EVENTuell is an app to plan and organize your private events. With its unique concept it offers you special opportunities to stay in contact with your guests and motivate them to interact with other guests and the party itself.

Project objective

Redesign of a process and application of different designthinking methods during the course of the project.

Project progress

Our team, consisting of Josh Cornau, Luca Stetter and Sven Barth, started with a last frustration brief in which you collect all situations in which you have been annoyed about an application.
We had already noticed for some time that private events created on Facebook often go down and only a small part of the invited people actually give feedback as to whether they participate in the event or not. However, the events are usually well attended, even by people who didn't respond to the invitation. We took this phenomenon to task and developed a solution: Eventually.



With our own research and interviews with people from our environment and at the university, we dealt with the following questions:

  • Which apps are used for event planning and organization?
  • How often are people invited to events?
  • How common is it not to respond to such invitations?
  • What are the reasons?

We wrote these questions and a weighting scale on a large poster and displayed it in the entrance hall of the university at lunchtime. By asking the students to place a nut on the weighting scales of our questions, we were able to quickly get a lot of opinions and generate a quantitative evaluation.

"On Facebook, there is an inflation of invitations. Private events come as well as unimportant public events - as a result the invitations themselves lose their value"


We decided quite quickly to develop a standalone application, which is integrable to any other social plattform via a link. This made us independent of any existing functions like on facebook or whatsapp. But this concept still did not solve the problem of the value of an invitation. 
As for us the value of an invitation was the keyword, we thought about how we could increase its value. So we contemplated about the term "value" itself:

  • social value
  • monetary value
  • personal value
  • value by need

With these ways to create a value, we designed different invitation scenarios for our app.




At this scenario the host chooses a few guests at the beginning and a maximum number of guests. Afterwards every invited person has to invite another, previously set, amount of people to the party. Trough this your invitation is more special and you are not just one of 50 people.

Pay what you want

This one is great for expensive parties. Everyone who announces to come to the party has to pay a voluntary price. By making the amount you paid public for every partymember you also involve social pressure.


High fidelity Prototype

After we had carried out user tests with our scenarios, we decided on the three most successful. At the end we designed the application with Sketch and implemented it in a Principle prototype.
