UNIT I INTRODUCTION TO QUALITY 9
Introduction, definition of quality, basic concept of quality, Quality assurance, Quality control, Quality
costs – measuring quality costs, Variation in process – causes of variation, Statistical quality control –
benefits and limitation of statistical quality control.
