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.

Below is the list of correct/incorrect examples of software process activities that help predict changes and make the software being developed more resilient to change. 1. Recording of requirements rational so that the reason why a requirement is included is known. This helps future change. 2. Requirements tractability that shows dependencies between requirements and between the requirements and the design/code of the system. 3. Design modeling where the design model documents the structure of the software. 4. Code refactoring that improve code quality and so makes it more amenable to change.
