Continual improvement is necessary for a business organization to retain or increase its customer base. A constant cycle of Plan–Do–Check–Act is needed to assess the current method of production and improve it. Influences that motivate change include legal requirements, technology, and facilities. However, the people, whether through customer feedback, or research and development have the ability to affect the most change. As a result, the procedures to manage the change should coordinate the relationship between people and other resources in an organized manner. A well–coordinated quality system model will balance the needs of the customer, employee, and supplier, with the tools, equipment, technology, so that the system can incrementally adjust to the change.
