Our Developer Brian did a great job developing our prototype in such short time. During this development phase we had a short meeting with him every week to get aware of the changes and the development. Brian was really helpful with implementing changes and new features.
When Brian, our developer, finished the prototype we started a user test with two contractors, Jasper and Rik. They were a great help for us in the beginning of our project thinking about the concept from the user perspective. Doing user tests is useful because by making use of their perspective we can investigate how our app or concept will be used in the end and what needs to changed for our concept to work. By involving Jasper and Rik we could see the app through their eyes and with more distance.
