This document provides an overview of quality management systems and ISO 9001:2008 certification. It discusses how customer expectations have changed from a time when customers had less choice to today's buyer's market where customers expect high quality and reliability. Implementing a quality management system helps organizations understand customer requirements and establish processes to consistently meet those requirements. Obtaining ISO 9001:2008 certification provides both internal benefits like improved productivity and employee satisfaction, as well as external benefits such as improved quality image and ability to enter global markets.
