Managing Software Quality Requirements

Abstract

This research study explores current quality requirements (QR) management practices in Australian organisations focusing on the elicitation, handling processes, challenges faced, quantification methods used and interdependency management. This research was conducted through six mini case studies, examining organizations that varied in size, structure, industry and function. A mixed methodology was utilised through an online survey for gathering quantitative data and semi-structured interviews for gathering explanatory qualitative data. The results found that five out of the six organisations studied did not have a formal and defined process for the handling of QRs. Large organisations treated QRs are part of their overall project specifications, while smaller organisations saw the management of QRs as more ad hoc. When prioritising QRs, Accuracy was considered the most important priority followed by Security and Reliability. The main challenges that organisations face in their management of QRs is defining and quantifying these requirements.
