The Source Code Inspection process is an efficient error detection method if implemented correctly. Inspections make even greater impact when the starting quality of the code is poor. Even if poor Inspection performance is realized as compared to results reported in the literature, the process with Source Code Inspections and Unit Test offers an overall improvement. If pressed for time, it is better to reduce Unit Testing rather than reduce Inspections. It is worth implementing inspection procedures well in order to obtain the maximum return.
Inspections are a high leverage activity.
The results obtained compared well with results reported from actual field studies of source code inspections found in the literature. A quantitative process modeling approach is being developed. Preliminary tests show the approach to be well suited for analyzing process level issues in software development. Presentation in Session Three, Advanced Track. 35, No. 9, September, 1992.
