When considering improvements in a test process, what is a common reason for emphasizing inspections and reviews?

Emphasizing inspections and reviews in the test process is beneficial primarily because they help to identify defects early in the development cycle, reducing costs and effort in later stages. Option C correctly identifies that inspections and reviews can address the lack of a simulation environment. When a simulation environment is not available, thorough inspections and reviews provide a means to assess the quality of the product without relying on executing tests in a specific environment. This approach can uncover issues and improve the quality of documentation, design, and code prior to system testing.

In the absence of a simulation environment, traditional testing methods might struggle to validate certain aspects of the software effectively. Inspections and reviews thus serve as a critical alternative method, contributing to a robust testing process by engaging stakeholders early in the evaluation of the product. This proactive approach can lead to the identification and rectification of defects before they propagate into later testing stages, significantly enhancing the overall test process.
