During the design review of several sections (modules) of software, the reviewers find an unusually high number of defects After defect correction and testing, which of the following can be expected of these sections?

When a section of the software has an unusually high number of defects, even after correction and testing, it is likely that these sections might still contain additional defects. This is based on the defect clustering principle, which suggests that defects tend to cluster in certain modules of the software. Consequently, these sections require more thorough testing and scrutiny to ensure all defects are identified and resolved. It is unrealistic to assume that these sections will be free of defects after initial corrections. They often need more comprehensive testing and more detailed test documentation to track and manage the corrections and any subsequent issues that may arise.
