The user research results were transformed into a first app architecture. Because the pilot requires a more simple version of the app than an app that would work in comercial use, we decided to create an app version 2.0 and an app version 3.0. We first translated all user needs into an architecture draft for 3.0 and then created a minimum viable product for the pilot. The app for the pilot for examle does not need a network, because only 10 people will take part in it. In oder to be able to programm in steps we also divided 2.0 features and started to define all features for 1.0 which will be a realistic guess to programm untill Christmas. We started programming in Java Script, html and css.
