Quality Control is the control of the operational techniques and the activities used to fulfill requirements of quality. One way to control quality of a product or service is to provide in-process and/or final inspection. The problem with inspection is that experts maintain that even with 100% inspection, inspection is only 80% effective – at best. So, defects, mistakes, flaws, and errors slip through the process and end up being noticed by the final customer. This is costly. This tarnishes the organization’s brand. This slows down production. Most of all, quality control is no longer a competitive strategy. More competitive organizations have found that it is better to build quality into the product or service than it is to try to find the defects and mistakes. More proactive organizations are building Six Sigma into the designs of new processes. It is referred to as Design for Six Sigma (DFSS).
