Software inspection entity relationship diagram (ERD), inspection team size, requirements specification.


Software inspection/review is recognized as an effective technique to improve software quality. Current literature has examined inspection performance, mostly through the introduction of different defect detection methods. However not much work has been done on exploring the relative effective group varying group size. There seems to be a variety of prescription for group size across different software artifacts (ranging 2-6) [1]. We explored the relative performance of varying group size for an ER model inspection in this study via 2 controlled laboratory experiments. Our findings showed no significant differences between interacting size of 2 and 4. Practical implication and limitations for this work are also discussed.
