Most quality models have defined usability as a
\r\nsignificant factor that leads to improving product acceptability,
\r\nincreasing user satisfaction, improving product reliability, and also
\r\nfinancially benefitting companies. Usability is also the best factor that
\r\nbalances both the technical and human aspects of a software product,
\r\nwhich is an important aspect in defining quality during software
\r\ndevelopment process. A usability risk consist risk factors that could
\r\nimpact the usability of a software product thereby contributing to
\r\nnegative user experiences and causing a possible software product
\r\nfailure. Hence, it is important to mitigate and reduce usability risks in
\r\nthe software development process itself. By managing possible
\r\nusability risks in software development process, failure of software
\r\nproduct could be reduced. Therefore, this research uses the Delphi
\r\nmethod to identify mitigation plans for reducing potential usability
\r\nrisks. The Delphi method is conducted with seven experts from the
\r\nfield of risk management and software development.<\/p>\r\n","references":"[1] Lavery, D.a.C., Gilbert, \u201cRepresenting Predicted and Actual Usability\r\nProblems,\u201d in Proc.of International Workshop on Representations in\r\nInteractive Software Development, 1997.
