How does the review process contribute to quality improvement in testing?

The review process plays a crucial role in quality improvement in testing primarily by enabling the identification of defects. Through systematic reviews, such as code reviews, requirement reviews, and test case reviews, teams can detect issues at various stages of development before they escalate into more significant problems. This proactive approach helps ensure that any defects are addressed early, which not only enhances the overall quality of the product but also reduces potential costs and time associated with fixing those defects later in the development cycle.

Identifying defects during reviews allows teams to gather feedback, improve processes, and refine testing strategies, ultimately leading to a more reliable software product. This reinforces the overall testing lifecycle by providing insights that can inform better practices and prevent similar issues from arising in the future. Thus, the review process is essential in fostering a culture of continuous improvement within software testing.
