ISO 9001 and ISO 9004 are intended to be used together to help you develop your  organisation towards world’s best practice.
ISO 9001 is the standard that you can be certified to from an accredited certification body. As you can see from the diagram , ISO 9001 is focused on ensuring that the supply chain provides customers with products and services which meet requirements. It also requires continual improvement.
