OC Curve (Operating Characteristic Curve)
Operating Characteristic Curve
Curve showing the probability of accepting a lot as a function of its actual quality level.
Examples
- 01The OC curve shows that the current sampling plan accepts a lot with 2 % defects about 60 % of the time.
- 02In the supplier review, the OC curve helps explain why a 'passed' inspection still lets bad lots through.
- 03After studying the OC curve, quality chooses a plan that rejects poor lots more reliably.
