What is a Critical to Quality (CTQ) characteristic?
Critical to Quality (CTQ) characteristics are features that affect the safety or function a product. A CTQ characteristic:
- Directly impacts the safety, regulatory, or functional performance requirements of the part
- Requires verification of part conformance during production
How do you know if a characteristic is CTQ?
CTQ characteristics are usually identified on the part drawing, and can be marked in several ways:
- A pill/cartouche surrounding the dimension on the part drawing
- Called out in a note somewhere on the drawing
How do I differentiate CTQ characteristics in my control plans and part drawings?
