Abstract:
Software inspections play an important part in ensuring the quality of software development. With the emergence of model-based development approaches, there is also a need for model inspections to ensure correctness of model-based artifacts. In practice, ad hoc inspections are regularly conducted, often by new and rather inexperienced colleagues, which are asked spontaneously to review an artifact of interest. The use of novices, such as trainees or student assistants, allows shorter review cycles at reduced costs. The quality of these ad hoc inspections is commonly attributed to different factors, often related to the reviewer. Increasing review time can be seen as an indicator that the reviewer takes the review serious. Furthermore, with more time spent, it can be assumed that more defects will be found. In this paper, we report the results of an experiment on ad hoc model inspections. Our results show that – contradictory to these assumptions and empirical findings from inspection
s of textual documents – the review time a reviewer decides to spend on a review has no significant influence on the effectiveness of ad hoc model inspections.
