Product & Process Control

Process ControlIntroduction

Let’s assume that you’ve just designed, verified and validated your own new product and now it’s time to move into full production.

As a Certified Quality Engineer, your job now is to ensure that the critical quality characteristics you defined in the design phase remain in a validated state of control.

You are also responsible for controlling other critical items such as the product design, the process associated with your product, or the process associated with your service, your raw material, your non-conforming materials, etc.

As you study to become a CQE, you’ll learn there are a number of key tools & methods that you will need to utilize to successfully keep your product or process in control.

Based on the latest Body of Knowledge, there are 5 key areas associated with the Product & Process (P&P) Control pillar of knowledge.
