  • Inside Information 2 ? Usability and User Research
  • 2009
  • Rapport (övrigt vetenskapligt)abstract
    • This report is a follow up to the Inside Information – Usability and User Research at UIQ Technology report that was made available in October 2006. The initial report was written from an industrial point of view aimed to market UIQ Technology through the demonstration of the UIQ usability and user research philosophy. UIQ Technology Usability Metrics (UTUM) was important result here. UTUM was considered an extremely cost-effective method for keeping in focus what is important for users and handset makers. It was a tool for guiding development decisions as well as for validating the worthiness of design concepts. The two parts in UTUM was perceived by the company as an innovation in their software development practice. The first part was the relationship to users and attitude to their participation in the design process. The second part was how the company immediately and directly incorporated this usability understanding into the software development process. UTUM, together with other usability methods and results presented in this report, have been produced in an action research manner. Due to the closure of the company, the main author of the 2006 report, and the same researchers who also supported the writing of the initial report, decided to produce a follow-up and closure version of the initial report; as a way to summarize the results from the academic and industrial cooperation. In this updated version, eight years of joint action research and cooperative method development surrounding usability and user research is concluded.

  • Personas is not Applicable Local Remedies Interpreted in a Wider Context

    • One of the major problems with participatory design is that it is extremely difficult to apply it to current developments. Software development for the mass market is one aspect of current developments which has been addressed. The problem of how to apply participatory design invariably leads to questioning its relevance to present-day circumstances. It is suggested that new patterns of dominance must be revealed. The usability method known as 'personas' has been demonstrated to remedy the problems of including social and political issues in mass market software developments. This paper demonstrates how the application of personas to a mass market software development project failed because of patterns of dominance in the telecom branch which were unrecognised at the time. The identifying of these patterns of dominance contributes to a better understanding of some of the new patterns of power and domination in mass-market software developments that PD stands before.

  • Developing Quality through Measuring Usability--The UTUM Test Package
  • 2007
  • Ingår i: WoSQ'07 : ICSE Workshops 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.

  • Reporting Usability Metrics Experiences
  • 2009
  • Ingår i: ICSE Workshop on Cooperative and Human Aspects of Software Engineering. - 978-1-4244-3712-2 ; s. 108-115
  • Konferensbidrag (refereegranskat)abstract
    • It is often claimed that software development is negatively affected by infrequent, incomplete and inconsistent measurements; improving with the help of metrics is an obvious solution. Software testing provides opportunities for measurement that give organizations insight in to processes. Usability testing is part of the testing area, although it is not a commonly addressed area within software engineering, perhaps because of a split between qualitative and quantitative paradigms. We compare a usability testing framework called UTUM with principles for Software Process Improvement, and find areas of close agreement as well as areas where our work illuminates new characteristics. UTUM is found to be a useful vehicle for improvement in software engineering, dealing as it does with both product and process. Our work emphasises the importance of the neglected area of usability testing. Our experience also illustrates how the metrics have been tailored to act as a boundary object between different disciplines.
