This is a textbook-cum-working manual on Statistical Quality Control and Quality Management. These two subjects are distinct from each other yet closely related as SQC techniques are central to Quality Management. Hence the book is divided into two parts: PART ? 1: STATISTICAL QUALITY CONTROL, PART - 2: QUALITY MANAGEMENT. Part-1 primarily deals with Shewhart Control Charts (often called the Statistical Process Control (i.e., SPC) and various types of Scientific Acceptance Sampling(SAS). Part-2 deals with various types of Quality Management techniques in which SQC (i.e., SPC and SAS) play a significant role. A distinct and bonus feature of the present edition of this book is that the completion of text portion in each chapter, a large number of questions ? objective, optional one line answer, short answer and responsive questions of the fundamental and practical nature have been answered under the head Solved Questions. However, this edition partly follows the general pattern of nine earlier editions. The Author wishes to acknowledge with thanks his gratitude to the number of users both from academic and industrial world, for offering valuable comments and suggestions, most of which have been incorporated in the present edition.
