Developing Quality through Measuring Usability--The UTUM Test Package
- 2007
-
Konferensbidrag (refereegranskat)abstract
- This paper presents a tool for building quality of use into software and the software process, in the form of a test package for mass market devices. It is developed for measuring user experience, which is seen as a more encompassing term than usability. The test package, which is under constant development, is the result of a long term cooperation between industry and academia, and is in use in indutrial development projects. It shows usability through the use of metrics, for efficiency, effectiveness and satisfaction, supported by qualitative judgements made by a test leader/usability expert. It gives a clear demonstration of quality, from the customer and end-user point of view. The case presented here, where the test has been performed concurrently in two countries, has been a quality assurance of the test package, which has been found to work efficiently and flexibly in a complex industrial environment, with complicated relationships between customers, partners and end-users.

Tidskriftsartikel (refereegranskat)abstract
- Based on a case study performed in industry, this work deals with a statistical analysis of data collected during usability testing. The data is from tests performed by usability testers from two companies in two different countries. One problem in the industrial situation is the scarcity of testing resources, and a need to use these resources in the most efficient way. Therefore, the data from the testing is analysed to see whether it is possible to measure usability on the basis of one single metric, and whether it is possible to judge usability problems on the basis of the distribution of use case completion times. This would allow test leaders to concentrate on situations where there are obvious problems. We find that it is not possible to measure usability through the use of one metric, but that it may be possible to gain indications of usability problems on the basis of an analysis of time taken to perform use cases. This knowledge would allow the collection of usability data from distributed user groups, and a more efficient use of scarce testing resources.
