Sampling Plans and Patterns Tutorial#

In manufacturing environments, Sampling is a key quality control method for monitoring processes and maintaining product consistency without inspecting every unit. Instead of performing 100% inspection, which can be costly and time-consuming, Sampling targets selected parts or batches at defined intervals or quantities. This approach helps detect variations early while keeping production efficient.

Within Critical Manufacturing MES, two main entities support this functionality: the Sampling Plan and the Sampling Pattern.

How They Fit Together#

The diagram below merges the user guide relationship diagrams for Sampling Plan and Sampling Pattern, showing how both configurations connect through the Step.
