Formulation of Usability Risk Assessment Model

Usability is considered as one of the significant factors of software product quality and becoming an emergent property of an entire closed and open system. Existence of usability problem has been discovered to cause many quality problems in several studies. Despite various efforts have been taken to overcome these problems, usability problems still exist in software products. This affects continuous interaction of an open system with the user and environment. This paper presents study on formulation of Usability Risk Assessment Model to identify, analyse and prioritize potential usability risk during Software Development Lifecycle (SDLC). Using this model, usability problems in software products are dealt before it occurs to produce more usable software product and continuous interaction of an open system with the user and environment can be ensured.
