• Key Concepts: 
  Acceptable Quality Level (AQL) is a quality management term used in SAP Quality Management (QM). It is a measure of the maximum number of defective items that can be accepted in a given sample size. AQL is used to determine the quality of a product or service and is usually expressed as a percentage. 
  
  How to use it: 
  In SAP QM, AQL is used to set the acceptable level of quality for a product or service. This level is determined by the customer and is based on their requirements. The AQL is then used to determine the sample size for inspection and testing. If the number of defective items in the sample exceeds the AQL, then the product or service is considered to be of unacceptable quality. 
  
  Tips & Tricks: 
  When setting an AQL, it is important to consider both the customer’s requirements and the cost of inspection and testing. It is also important to ensure that the AQL is realistic and achievable. 
  
  Related Information: 
  The AQL can be used in conjunction with other quality management tools such as Statistical Process Control (SPC) and Design of Experiments (DOE). These tools can help to identify potential problems with a product or service before they become an issue.
