Patterns of Continuous Requirements Clarification
Artikel i vetenskaplig tidskrift, 2015

In software projects involving large and of- ten distributed teams, requirements evolve through the collaboration of many stakeholders, supported by online tools such as mailing lists, bug tracking systems, or online discussion forums. In this collaboration, requirements typically evolve from initial ideas, through clarification, to the implementation of a stable requirement. Deviations from this expected course might in- dicate requirements that are poorly understood, need further negotiation, or better alignment with project goals. If not addressed timely, such problems can surface late in the development cycle with negative consequences such as rework, missed schedules, or overrun budget. This paper presents an approach that provides project managers’ with timely awareness of such requirements-related risks, based on automatic analysis of stakeholders’ online requirements communication. We describe a clarification classifier that automatically analyzes requirements communication in a project and detects clarification events, a catalogue of clarification patterns, and a pattern matcher that suggests communication patterns based on our pattern catalogue. Our approach has been empirically constructed and evaluated in a case study in the IBM Rational Team Concert (RTC) project. We discuss the applicability of our approach in other projects as well as avenues for extending our pattern catalogue towards a theory of clarification patterns.
