Example: If you always park to one side, even if the car fits → Cp high, but Cpk low. If you park in the middle consistently → Cp ≈ Cpk (excellent process). --- 🚦Takeaway Cp = Capability (potential).

Interpreting Cpk in One-Sided Specs — in Simple Terms In process capability analysis, we often focus on Cpk when only one spec limit is defined — like: Moisture ≤ 5% Protein ≥ 12% In these cases, we ...

工程能力指数（Cp・Cpk）は、「この工程は規格の範囲内に製品を作り続けられるか」を数値で表したものです。 製造現場では、同じ条件で作っても製品の寸法・重量・硬度などにはばらつきが生じます。このばらつきが規格の幅に対してどれだけ小さいかを ...

So what is the real difference when looking at Cpk and Sigma Level? If you’re new to Six Sigma, there is no shortage of acronyms and calculations to keep in mind as you work on your knowledge base.

This example illustrates how you can use the OUTPUT statement to compute confidence limits for the capability index C pk. You can request the approximate confidence limits given by Bissell (1990) with ...

In this example, the capability index C pk is computed for the amplification data in AMPS. To examine the accuracy of this estimate, the following statements calculate a 90% confidence interval for C ...
