• Key Concepts: 
  Subpopulation is a term used in SAP Quality Management (QM) to refer to a group of items that have been identified as having similar characteristics. This group of items can be used to represent the entire population of items in a given process or system. Subpopulations are typically used to identify and analyze trends in quality data, and can be used to make decisions about how to improve the overall quality of a process or system. 
  
  How to use it: 
  In SAP QM, subpopulations can be created by selecting a set of items from the population that have similar characteristics. This selection process can be done manually or automatically using statistical methods. Once the subpopulation has been identified, it can be used to analyze trends in quality data and make decisions about how to improve the overall quality of the process or system. 
  
  Tips & Tricks: 
  When creating subpopulations, it is important to ensure that the selection process is unbiased and that all items in the population are given equal consideration. Additionally, it is important to ensure that the subpopulation is representative of the entire population so that any conclusions drawn from the analysis are valid. 
  
  Related Information: 
  Subpopulations are closely related to statistical sampling techniques, which are used to identify and analyze trends in large datasets. Additionally, subpopulations can be used in conjunction with other quality management tools such as root cause analysis and failure mode and effects analysis (FMEA).
