Designing for usability and user engagement : Evaluating the combination of competitive, parallel and iterative design process for higher usability and user engagement in a safety-oriented mobile application

Sammanfattning: Usability plays an important role in user-experience design and when designing for usability it is necessary that a suitable design process is planned and executed. A question designers may have experienced is "what is the best design process for this project?" when in reality, the best design process is a combination of several design processes. This thesis combines competitive, parallel and iterative design processes when designing for usability and user engagement. The three design processes segues into each other as they aid in the process of identifying current problems with the design, find solutions that are both tested and untested, and then iteratively improves these solutions to a point of satisfactory result. The result shows, however, that combining three design processes can be expensive in terms of resources and that instead of having a set number of design processes with then resources divided between the processes, resources should determine the numbers of design processes to combine.
