Process Capability

Format Web-based

Process Capability is the extent to which a stable process meets customer specifications. It applies to all businesses and industries and to aspects of life. Learn concepts that can be put to immediate use in the workplace to help you measure and improve processes.

Gain an understanding of process capability and how it can be used to predict the potential failure rate from a process. Learn the statistical techniques that are used to predict the complete output of a process based on a relatively small sample. A Process Capability Analysis is a predictive tool that enables right decisions to be made based on data and facts. You will use practical exercises to learn how to carry out effective process capability studies.

Course Overview

Learning Objectives:

  • Determine how well a process is able to meet customer requirements by measure of process capability and identify when one process is more capable than another.
  • Distinguish capable from non-capable processes.
  • Identify how sample measurements are used to estimate population values.
  • Determine which Control Chart type is most appropriate for monitoring a particular process parameter.
  • Compute Cp, Cpk, Pp, and Ppk values for processes using continuous data.
  • Interpret Cp, Cpk, Pp and Ppk and relate them to a defect level.
  • Take relevant process information for a process using discrete data.
  • Calculate process assessment measurements.
  • Look at a powerful operation metric called Rolled Throughput Yield.


A knowledge of Basic Statistics is helpful.

Who Should Attend:

People with knowledge of basic statistics including measures of central tendency and dispersion, histograms, and control charts.

WebEx – Virtual Course: Advance Preparation and Student Information

Join a Test Session

We strongly suggest that you join a WebEx test session in advance of your scheduled virtual training, using your preferred web browser. This can help prevent problems launching content the day your training begins.

If you do not have administrative privileges on the SAME computer you will be using the day of your training (i.e., your workstation within your organization) you may need the assistance of your local IT/IS help desk staff for the platform to engage correctly.

To join a test session (meeting), click here and enter your name and email address to join. If successful, you will see a screen that says "Congratulations! Your system is now set up properly ..."

Deactivate Pop-up Blockers

You should deactivate any pop-up blockers, spam filters, and company firewalls that could prevent the WebEx client platform or web-based course from working properly. Third-party toolbars such as Bing, Yahoo, and Google should also be disabled due to their own pop-up blocking capabilities.
