　　the qms market sectors are divided between plm, mes, and erp suppliers that offer qms systems as a part of their overall enterprise software portfolio. most mes products offer quality management as an integrated component of an overall manufacturing planning and execution portfolio. some of the large plm providers offer mes as a component of their design/build/operate lifecycle. most of the current qms market are pure play qms providers, many representing point solutions that focus on specific quality technologies.

　　today, the term that describes the market is qms, where tqm (total quality management) refers primarily to the underlying methodology and approach to the quality process. perhaps the most common deion of how quality and quality improvements have evolved into present-day qms is the identification of: quality inspection, quality control, quality assurance, and tqm.

　　from quality control to quality assurance

　　the quality inspection stage began about the same time (early 20th century) that large manufacturing and mass assembly production lines emerged. companies like ford, then one of the world’s largest manufacturers, employed teams of inspectors to check the quality of the model-t car. some elements of statistical quality control were introduced in the 1930s and ’40s, but this method of quality control was the primary process until the 1970s and ’80s when quality assurance emerged from the japanese auto manufacturers.

　　the quality assurance (qa) phase focuses on pre-production processes and relies on quality standards (most notably iso 9000) or instructions to assist with reduction of the risk of failures and mistakes in the processes used to produce a product or service. iso 9000 is now used extensively throughout the world as the de facto guide to quality assurance.

　　the fourth stage, tqm, involves understanding and implementing quality management principles and concepts in every aspect across the organization and enterprise from product design to manufacturing to customer feedback. tqm is focused on continuous process improvement procedures in which all organizations of the enterprise are involved and committed to quality as a mindset and process. in other words, the quality is built into the enterprise and overall process, assuring a quality product.

　　qms extends beyond manufacturing

　　overall growth in the qms software market will be driven primarily by the demand for more reliable products by consumers in emerging markets. one of the major trends in this market is the rapidly growing sales of goods over the internet that will require producers to offer quality products that will not be returned, as processing these returns due to quality issues represents a major cost center for internet-based sales.

　　while quality assurance and overall continuous improvement methods have been in place for decades in discrete manufacturing, the adoption of these quality methods have moved to other industries like bio-tech/pharma, medical devices, consumer goods and services, and non-manufacturing industries like power generation and utilities, financial and banking services, consumer goods, and food & beverage. additionally, the qms market now includes technologies focused on occupational safety and environmental and sustainability issues, further expanding the reach of the quality assurance space.
