Verification and correction are distinct processes in software development. The former involves evaluating a system component to determine whether it satisfies the specified requirements. For instance, test cases are executed to confirm a module produces the expected output for a given input. The latter, on the other hand, identifies and removes the root cause of failures detected during verification. If a test case fails, this process is employed to locate and rectify the fault in the code.
These activities are crucial for producing reliable and robust software. Thorough verification increases confidence in the product’s quality and minimizes the risk of defects in production. Effective correction ensures that identified issues are properly resolved, preventing their recurrence. Historically, these processes have evolved from ad-hoc practices to structured methodologies, reflecting the increasing complexity and criticality of software systems.
