  • Developing Quality through Measuring Usability--The UTUM Test Package
  • 2007
  • Konferensbidrag (refereegranskat)abstract
    • Artikeln presenterar ett sätt att bygga in användningskvalité i mjukvara och mjukvaruprocesser, genom att använda ett testpaket för mobiltelefoner. Testpaketet är ett resultat av ett långt samarbete mellan industrin och akademin. Den påvisar användbarhet med hjälp av mätningar av användarhetsaspekter, som kompletteras med testledarens subjektiva bedömning. Artikeln är baserad på tester som har utförts parallelt i två länder. Vi har funnit att testet har fungerat i en komplicerad industriell miljö med komplicerade förhållanden mellan kunder, partners och slutanvändare. Användbarhet, mätningar, kvalité, UTUM

  • Identifying organizational barriers-A case study of usability work when developing software in the automation industry
  • 2014
  • Ingår i: Journal of Systems and Software. - Elsevier. - 0164-1212. ; 88:February, s. 54-73
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigates connections between usability efforts and organizational factors. This is an important field of research which so far appears to be insufficiently studied and discussed. It illustrates problems when working with software engineering tasks and usability requirements. It deals with a large company that manufactures industrial robots with an advanced user interface, which wanted to introduce usability KPIs, to improve product quality. The situation in the company makes this difficult, due to a combination of organizational and behavioural factors that led to a "wicked problem" that caused conflicts, breakdowns and barriers. Addressing these problems requires a holistic view that places context in the foreground and technological solutions in the background. Developing the right product requires communication and collaboration between multiple stakeholders. The inclusion of end users, who fully understand their own work context, is vital. Achieving this is dependent on organizational change, and management commitment. One step to beginning this change process may be through studying ways to introduce user-centred design processes.

  • Meeting organisational needs and quality assurance through balancing agile and formal usability testing results
  • 2011
  • Ingår i: Lecture Notes in Computer Science. - Springer. ; s. 275-289
  • Konferensbidrag (refereegranskat)abstract
    • This paper deals with a case study of testing with a usability testing package (UTUM), which is also a tool for quality assurance, developed in cooperation between industry and research. It shows that within the studied company, there is a need to balance agility and formalism when producing and presenting results of usability testing to groups who we have called Designers and Product Owners. We have found that these groups have different needs, which can be placed on opposite sides of a scale, based on the agile manifesto. This becomes a Designer and a Product Owner Manifesto. The test package is seen as a successful hybrid method combining agility with formalism, satisfying organisational needs, and fulfilling the desire to create a closer relation between industry and research.

  • Reporting Usability Metrics Experiences
  • 2009
  • 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.

  • SPI success factors within product usability evaluation
  • 2010
  • Ingår i: Journal of Systems and Software. - Elsevier. - 0164-1212. ; 83:11, s. 2059-2072
  • Tidskriftsartikel (refereegranskat)abstract
    • This article presents an experience report where we compare 8 years of experience of product related usability testing and evaluation with principles for software process improvement (SPI). In theory the product and the process views are often seen to be complementary, but studies of industry have demonstrated the opposite. Therefore, more empirical studies are needed to understand and improve the present situation. We find areas of close agreement as well as areas where our work illuminates new characteristics. It has been identified that successful SPI is dependent upon being successfully combined with a business orientation. Usability and business orientation also have strong connections although this has not been extensively addressed in SPI publications. Reasons for this could be that usability focuses on product metrics whilst today's SPI mainly focuses on process metrics. Also because today's SPI is dominated by striving towards a standardized, controllable, and predictable software engineering process; whilst successful usability efforts in organisations are more about creating a creative organisational culture advocating a useful product throughout the development and product life cycle. We provide a study and discussion that supports future development when combining usability and product focus with SPI, in particular if these efforts are related to usability process improvement efforts.
