Careful measurement is key to managing your quality control processes. Use the following steps to ensure that you measure the right quality-control factors in the right way.

  1. Determine what to measure (the items or processes you decide to measure are called metrics).

  2. Determine your measurement process by selecting the best process for your needs.

  3. Define exactly how you’ll use the selected measurement process.

  4. Train your employees on the proper measurement process.

  5. Perform gauge repeatability and reproducibility (R&R) tests to determine measurement variation.

  6. Perform the measurements and compare to customer specifications.

  7. Confirm the quality of your data with compare-and-review checks and the help of a computer.

  8. Make sense of your data with coding and different data charts.
