ISO 9001 Quality Management System is a globally recognised quality management system that aims to increase customer satisfaction by meeting customer expectations, needs and regulatory requirements. It determines the Quality Management System conditions at many points from the organisational structure of the organisation to the satisfaction level of its customers, from the analysis of the collected data to the effective management of the processes, from internal audits to product design, from purchasing to sales. The ISO 9001 Standard is essentially a control mechanism. The purpose of this standard is to reduce, eliminate and, more importantly, prevent errors and defects. The standard is not directly related to product and service quality, but to the quality of the management system. The basic assumption here is that if an effective Quality Management System is established and implemented, quality products and services will be produced to meet customer needs.
