Clause 4.4

Objectively, I will say that it is on the non-mandatory list. Clause 4.4.1 states that organizations must determine their processes, their inputs, and outputs and how they interact. Nowhere does it say there has to be a document, but everyone is waiting to see the process map. Clause 4.4.2 is par excellence part of the non-mandatory list. Organizations are invited to reflect on what documents to create for their quality management system.
A clause may not be listed in any of those lists. For example, clauses 5.3, 6.3 or 7.4. An organization may have leadership practices or communication practices and evidence and yet without any non-mandatory document. Same way, an organization may answer to clause 6.1 without considering the need for a non-mandatory document. Only the mandatory list is relevant. The non-mandatory list is a sort of adviser based on Advisera’s experience.
