Process Capability Analysis (Cp, Cpk, Pp, Ppk) | SigmaExacta Tutorial


Listen Later

Are you looking to measure how well your process meets customer specifications? In this tutorial, we demonstrate how to perform a professional Process Capability Analysis using the free suite of tools at SigmaExacta.com.

We cover the essential indices for both short-term and long-term performance, helping you differentiate between a process that is simply "narrow" and one that is actually "centered."

📌 WHAT YOU WILL LEARN:

▶︎ CORE CONCEPTS: Understanding the difference between Cp (Capability) and Cpk (Centering), as well as Pp/Ppk (Performance).

▶︎ THE MATH: A breakdown of the mathematical formulas used, including Sigma Within and Sigma Overall.

▶︎ HISTORICAL CONTEXT: A brief tribute to Walter A. Shewhart, the father of Statistical Process Control (SPC).

▶︎ STEP-BY-STEP GUIDE:

How to input datasets and set Specification Limits (USL, LSL).

How to interpret I-Charts (Individual Control Charts).

Visualizing distribution plots and normality tests.

▶︎ REPORTING: How to export your results to Excel for professional documentation.
