Understanding Process Capability ─ Explanation and Formula for Cpk
Workingbear has already spent a good amount of time explaining what Cp (Precision) and Ck (Accuracy, sometimes called Ca) mean, and what each represents. We’ve also learned that using Cp or Ck alone can give an incomplete picture when it … Continue reading

Introduction to Process Capability – Understanding Ck or Ca (Accuracy)
What Is Ck or Ca? Ck, which some people now refer to as Ca (Accuracy), represents how close a process output is to the target value. Using a target-shooting example: if someone fires six bullets and all land near the … Continue reading

Introduction to Process Capability – Understanding Cp (Precision)
Understanding Cp as a Process Capability Indicator Cp (short for Precision) is a measure of how tightly a process is centered and how consistently it produces results. Using a target-shooting analogy, if someone fires six bullets and they all hit … Continue reading
