Software inspection is recognised as the most effective means of finding defects. In spite of its important role in software development, existing capability models have not addressed inspection issues or looked for inspection- related improvement activities to a sufficient extent. The inspection-tailored capability model presented here provides a method for evaluating inspection process capability and supports the location of weak points in a company's inspection process. The first experiments reported in the paper are promising, and the evaluation process discovered correctly focused improvement ideas which were also agreed on by the company concerned.
