Carefully read the question and answer accordingly. A key concept of quality control is that all work products

Should be subject to careful scrutiny at every step of the process, from initial development to final output. This means that every part of a project or task should be checked and double-checked for errors, inaccuracies, or inconsistencies. This can involve various methods, such as peer review, automated testing, manual checking, and more. The goal is to ensure that the final product is as close to perfect as possible, and that any potential issues are identified and corrected as early as possible. This not only improves the quality of the work, but also saves time and resources by preventing the need for extensive corrections or rework later on.
