A Quality Improvement Strategy for Critical Product and Process Characteristics

 

Purpose

This publication is designed to provide the quality practitioner, engineer, and other technical personnel with a comprehensive description of the methodology associated with bringing critical product and process characteristics into a state of control and capability. The methodology is divided into four basic sections, and the procedures to be employed are presented on a series of flowcharts.

While the flowcharts are generally self-explanatory, a significant amount of understanding as related to industrial statistics and experimental design on the part of the reader is assumed. This manual, in fact, serves as a capstone document for the Experimental Design and Industrial Statistics series offered by The ROI Alliance.
