This comprehensive guide serves as a technical manual for performing and interpreting capability analysis. It argues that capability indices like Cp, Cpk, and Ppk are essential for quantifying an organization’s ability to meet customer specifications. The document provides detailed explanations of the statistical assumptions required—such as normality and stability—and offers guidance on how to use software tools to streamline calculations. Evaluatively, this is an industry-standard resource that provides high-quality technical instructions. It is particularly strong in its distinction between short-term capability and long-term performance, a critical nuance in Six Sigma projects. The guide is highly practical, including checklists and decision trees to help practitioners choose the right metrics. While clearly intended to support the publisher's training programs, the information is robust, accurate, and serves as an excellent technical reference for anyone conducting quality audits or process redesign.
