Prediction of usability: Comparing method combinations

摘要: The objective of this thesis is to obtain knowledge regarding how effective user centred evaluation methods are and evaluations conducted by IT professionals. This will be achieved exploring in experimental practical settings. gained these studies should inspire suggestions for further research improvements on the activity. Two were conducted. One compares results from using three methods, other examines two factors while conducting heuristic evaluation. show that think-aloud method was most finding realistic usability problems methods. number critical found during increases, if prior evaluations. Further, settings performed. professionals participating those software development process Scrum plan their work. infrequently projects, compared testing activities like acceptance testing. main type qualitative. Few participants measure performance or use surveys gather quantitative experience. get feedback users an informal way peers. Many a mixture gathering outcome shows encouraged include whenever possible when evaluating software, example method. Using also recommended. In addition, evaluate frequently, rather than waiting right time conduct thorough To advance field further, researchers who want improve activity study could combined efficient qualitative made more effective.
