Are the Perspectives Really Different? – FurtherExperimentation on Scenario-Based Reading of Requirements

摘要: Perspective-Based Reading (PBR) is a scenario-based inspection technique where several reviewers read document from different perspectives (e.g. user, designer, tester). The reading made according to special scenario, specific for each perspective. basic assumption behind PBR that the find defects and combination of detects more compared same amount with single This paper presents study which analyses differences in perspectives. partial replication previous studies. It conducted an academic environment using graduate students as subjects. Each perspective applies modelling technique: use case user perspective, equivalence partitioning tester structured analysis design A total 30 subjects were divided into 3 groups, giving 10 per results show (1) there no significant difference among three terms defect detection rate number found hour, (2) coverage perspectives, (3) simulation shows enough detect relatively small chosen statistical test. suggest multiple may not give higher single-perspective reading, but further studies are needed increase understanding difference.
