Introduction

Quality can be defined in many ways, ranging from “satisfying customers’ requirements” to “fitness for use” to “conformance to requirements.” It is obvious that any definition of quality should include customers, satisfying whom must be the primary goal of any business. Experience during the last two decades in the U.S. and world markets has clearly demonstrated that quality is one of the most important factors for business success and growth. Businesses achieving higher quality in their products enjoy significant advantage over their competition; hence, it is important that the personnel responsible for the design, development, and manufacture of products understand properly the concepts and techniques used to improve the quality of products. Statistical quality control provides the statistical techniques necessary to assure and improve the quality of products.
