Log-based approach for performance requirements elicitation and prioritization

Abstract

Requirements engineering activities are a critical part of a project's lifecycle. Success of subsequent project phases is highly dependent on good requirements definition. However, eliciting and achieving consensus on priority between all stakeholders is a complex task. Considering software development of large scale global applications, the challenges increase by the need of managing discussions between groups of stakeholders with different roles and background. This paper presents a practical approach for requirements elicitation and prioritization based on realistic user behaviors observation. It uses basic statistic analysis and application usage information to automatically identify the most relevant requirements for majority of stakeholders. An industry case illustrates the feasibility and efficiency of our approach.
