Procedural changes are under control. That's what the following material will now do. Use ISO 9000-2 if you need some help implementing ISO 9001, ISO 9002, or ISO 9003. Use ISO 9000-3 if you are in the software business and you want to use ISO 9001 to set up a quality system. Use ISO 9000-4 if product dependability is important.
Dependability means reliability, maintainability, and availability.
Use ISO 9001 if you design, develop, produce, install, and service products, and if your customers need to be satisfied that product nonconformities will be avoided. ISO 9001 presents a Quality Assurance Model that will help you to develop the appropriate quality system. Use ISO 9002 if you produce, install, and service products. ISO 9002 presents a Quality Assurance Model that will help you to develop the appropriate quality system. Use ISO 9003 if product quality can be assured through final inspection and testing.
