Purpose – To see how different processes during the development of a User Interface affect the quality of its user-friendliness.
Method – Case study with interviews and contextual observations and a design process where several iterations of prototypes was used. Lastly an analys where the process used during the development is studied and the quality of the User Interface is valued from a number of defined factors.
Findings – The study shows that a design process with a focus on user-friendliness requires a lot of work beforehand and takes longer before an actual result kan be achieved while a process where user-friendliness is not a focus gives faster results but creates problems in the future because of a lower quality on the user-friendliness of the User Interface.
Implications – The study shows that a while process with a focus on user-friendliness takes more resources and time in the beginning it produces a higher quality of work which saves time and resources in the future. The study therefor other studies of how a user-friendly User Interface can and should be developed.
Limitations – The study lacked an opportunity to do testing in the User Interface’s real environment and is instead based on theories based on ISO’s definition of Quality in use instead of user tests which could have given a more credible result. The study also only studies two different processes and their result.
