Explain why program inspections are an effective technique for discovering errors in a program. Program inspections are effective for the following reasons: 1. They can find several faults in one pass without being concerned about interference between program faults. 2. They bring a number of people with different experience of different types of errors. Hence. the team approach offers greater coverage than any individual can bring. 3. They force the program author to re-examine the program in detail – this often reveals errors or misunderstandings. 4. Inspections require additional costs during design and development. 5. Inspections are very effective in finding bugs.
