What you'll learn
  • Learn to build histograms and compute the capability statistics in Microsoft Excel
  • Calculate and interpret process capability indices like Cp, Cpk, Pp, Ppk and Cpm.
  • Understand the exact differences between Cpk and Ppk
  • How to apply Process Capability Analysis to manufacturing improvement projects or new parts
  • Interpret the results of a capability study to drive process improvement
  • Advanced PCA topics such as dealing with one-sided tolerance and non-centered process targets, estimating percent defective using capability indices, and combining PCA with quality costing.
  • Basic knowledge of manufacturing
  • Basic knowledge of print reading and mathematics
  • Eagerness to expand quality knowledge base

Capability analysis is a computational method for comparing the output of a manufacturing process to its engineered specification limits. It's also an essential set of tools for new process development, 6-sigma projects, Statistical Process Control, and process monitoring. This set of tools can be applied to product characteristics such as its size, weight and hardness, or to process characteristics such as temperature, voltage or flow.

This class, "Process Capability Analysis" starts at the beginning of how manufacturing processes are developed and analyzed. It moves on to the basic concepts of capability analysis along with it applications and math (both "on paper" and in Excel). You will learn how to analyze capability data for a population, for a sample drawn from a population, and from the data found on control charts. At the end, you will also learn more advanced topics such as dealing with one-sided tolerances and an alternate capability index call Cpm. Plus, you'll receive all the Excel templates and "cheat sheets" you'll need to apply this to your manufacturing projects.

By the end of this course, you will have a thorough understanding of capability analysis, and be able to apply these tools broadly across a wide range of production problems.

Also, if you are studying for your ASQ CQE, CQT or CQIA exams, this is essential material. I carefully explained the difference between Cpk and Ppk, between analyzing a population and a sample, and how to interpret your capability analysis results; all critical elements on these exams.

Hear what you're colleagues are saying about Process Capability Analysis:

“This Process Capability Analysis class is awesome!” - Lawrence M.

“Clarity on the confusing Process Capability concepts and how to apply them was well explained. Lecture very good and passionate about the subject. Thank you very much, really enjoyed the course from start to finish.” - Kemsley J.

“I'm a quality manager, consultant and project manager in the food industry. This course was a great way to for me to gain experience with process capability analysis. The explanations were thorough and the examples made the math and statistics come to life. I recommend this to anyone who wants to better understand the measures of process capability.” - Chris F.

“A comprehensive knowledge of utilizing Pp and Cp Indices. Also the instructor have good knowledge and understanding of the topic.” - Nasir M.

“I work in manufacturing and appreciated this courses focus on Cpk and Ppk . it gave me a better understanding of what I was looking at when i analyzed process capability data. it is definitely worth taking if you use process capability charts. Easy to follow and made a dry topic easy to follow and complete!” - Robin S.

“Great course! If you work in a manufacturing environment, you will find that the lessons are very applicable to your everyday dealings with quality. The instructor (Ray) mentions that even many quality professionals are 'fuzzy' with some of these concepts. I have found that to be true in my experience. I much appreciate Ray Harkins for delivering this great content!” - Charles S.

“Great refresher course!” - Wallace Y.

Preview 16:33

A discussion of the available measurement systems and their accuracies.

07 Measurement Systems, Pt 1
08 Measurement Systems, Pt 2

Should you measure 100% of the parts you produce or just a sample of them? It depends on the application.

09 Sampling Options, Pt 1

Picking the correct sampling option for your application.

10 Sampling Options, Pt 2

Why a 30 piece sample size matters.

11 A Quick Word about Sampling Size

Understanding the arithmetic mean as a cornerstone to Process Capability Analysis

12 The Arithmetic Mean

How to measure the spread, or dispersion of data.

13 Standard Deviation

The histogram is one of the seven quality tools. It is effective is visualizing your capability data, and estimating its underlying probability distribution.

14 Building a Histogram is Excel
15 Excel's Data Analysis Add-in

The most common underlying statistical distribution and a key input to process capability analysis.

16 The Normal Distribution, Pt 1

A continued exploration of this very important probability distribution.

UPDATE: Practical Exercises

Once you calculate the estimated x-bar and sigma for a population, and determine that it has an underlying normal population distribution, you can plug your parameters into Excel to easily calculate the percent of the population above and/or below values you choose. This method is an excellent way to estimate the percent of a population outside your specification limits.
