The Push and Pull of Part and System

As the 20th century came to a close, manufacturers realized the need to transform thinking from the product to the system. Manufacturers were no doubt exhausted from having to spot a defect along the process and either scrap the product or send it back into the process for rework. It made economic sense to begin considering the system.

If the company assures its customers the product will be produced without error, the company saves on rework and parts. Manufacturers began speaking in terms of quality assurance, not control.
Within the realm of spotting and reducing defects come the terms correction and corrective action. If quality is about finding defects in products and reducing the occurrence of them in the processes, correction and corrective action certainly have their parts to play. However, like quality control and quality assurance, people often confuse the meaning of these two terms.
Correction is an action taken to eliminate a detected nonconformity. On the other hand, corrective action is taken to eliminate the cause of the detected nonconformity. This requires understanding the root cause of the detected nonconformity and taking action to eliminate the root cause(s). To stress the interdependency of these two activities the correction and corrective action may be required in many scenarios.
Whether discussing control or assurance, correction or corrective, your business cannot afford to view your products and your processes independently. Yet, many companies still refuse to take the steps needed to fully integrate quality throughout the company. Because resources are involved, organizations will hope for the best without preparing for the worst. This is shortsighted, to say the least.
Members of the quality community need to make sure they do not contribute to the confusion. Help clarify quality terminology for executives and non-quality people alike. If need be, begin speaking in terms of continuous improvement and the tools needed to set that in motion and continue having an impact within your business.
