In this movie, we'll continue to explore the Quality Control process. As mentioned previously, Quality Control is concerned with measuring specific results to determine whether the project is in compliance with quality standards and, if not, the next step would be to take any necessary corrective action to resolve the discovered issues. Corrective actions may involve something like rework and rework includes actions to correct deficiencies that are discovered through quality testing. It may result in scrapping an entire product built and starting over. It's usually costly and naturally causes delays within the Schedule. In other cases when defects are found they will need to be accepted. Perhaps there's no known resolution or to fix the defect would be too costly. Unfortunately, a common way around this, in the software world anyway, is to create patches or workarounds and that often leads to problems later down the line. Corrective actions may also result changes within the processes. Quality Control is also responsible for validating deliverables once they've been completed as well as validating changes. As a result of executing the work, tangible deliverables were created. Once created they're sent to Quality for inspection. If the deliverable passes inspection they're validated and then sent to be verified where the customer formally approves and signs off on that completed deliverable. Validation, which is this quality step, is focused on determining whether the deliverable is accurate and complete. The verification process later will measure it against the acceptance criteria of the corresponding requirements. In regard to validating changes, once changes are approved and then implemented, Quality Control measures whether they're implemented appropriately and whether the change achieved the desired result. If deliverables or changes could not be validated, then some form of action will need to be taken. At this point we've covered several aspects of quality, particularly in relation to the Quality Control process. This includes understanding the concept of prevention versus inspection, several quality tools and then the validation of deliverables and changes. And that wraps up this review of controlling quality.
