  Operating characteristic curve (OCC) is a graphical representation of the relationship between the probability of a product being accepted and the probability of it being rejected. It is used in Quality Management (QM) to determine the optimal sampling plan for a given quality level. The OCC is used to determine the sample size, acceptance number, and rejection number for a given quality level. 
  
  How to use it: 
  The OCC is used to determine the optimal sampling plan for a given quality level. The OCC is used to calculate the sample size, acceptance number, and rejection number for a given quality level. The OCC can be used to determine the probability of accepting or rejecting a product based on its quality level. 
  
  Tips & Tricks: 
  When using the OCC, it is important to remember that the sample size should be large enough to ensure that the results are accurate. Additionally, it is important to remember that the acceptance and rejection numbers should be adjusted based on the quality level of the product.
