Abstract

Over the past few years, agile methods have recorded impressive results in the software engineering field basically in terms of business value and time to market. Similarly, software usability has been the major success factor for interactive systems. Agile usability engineering has been motivated as a booming solution to develop better usability in a cost-effective manner. eXtreme Scenario Based Design (XSBD) is one of the effective agile usability approaches. However, XSBD does not provide explicit metrics to quantify the software usability. In this paper, we propose the Quantified eXtreme Scenario Based Design (QXSBD) approach, which complements XSBD with a set of usability metrics collected from the agile architecture-centric approach and the Quality in Use Integrated Model (QUIM). Further, QXSBD specifies the subset of usability metrics that need to be assessed at the major milestones in agile process. This integration employs the Usability Critical Parameters Workshop (UCPW) to provide engineering practices defining the usability requirements and design goals. We demonstrate the QXSBD, process through customer request project case study. The obtained results have shown that usability issues have been reduced by about 30%. Noticeable end user satisfaction has been achieved while maintaining the project total cost.
