Context of the organization. This new clause is not very clear. For me the entire ISO 9001:2015 has been jumbled too much. Some place it says no need, and, in another place, it says if needed then you can have it. This is confusing. ISO 9001:2008 was very clear and one can understand what actually was needed.
Determining the internal and external context is required by ISO 9001:2015. What is not mandatory is to have it documented. I think about the context of an organization as a way of thinking about the surroundings, the environment where an organization is operating, to avoid “making castles in the air”, to avoid big plans without keeping the feet on the ground. And to promote a reflection about risks and opportunities for the organization based on internal and external issues.
