• Key Concepts:
  Double-sampling inspection is a quality control method used in SAP Quality Management (QM). It is a statistical sampling technique that uses two samples to determine the quality of a product or process. The first sample is used to determine the acceptability of the product or process, and the second sample is used to confirm the acceptability of the product or process.
  
  How to use it:
  In SAP QM, double-sampling inspection is used to inspect incoming materials and finished products. The first sample is inspected for defects, and if the defects are within acceptable limits, then the second sample is inspected. If the defects in the second sample are also within acceptable limits, then the product or process is accepted.
  
  Tips & Tricks:
  When using double-sampling inspection in SAP QM, it is important to ensure that both samples are taken from different batches of material or products. This will ensure that any defects found in one sample are not present in the other sample. Additionally, it is important to ensure that both samples are inspected by different inspectors to reduce bias.

  Double-sampling inspection is one of several quality control methods used in SAP QM. Other methods include single-sampling inspection, attribute sampling, and variable sampling. Additionally, SAP QM also provides tools for analyzing and reporting on quality data such as defect rates and nonconformances.
