Requirements for documented procedures in ISO 9001:2015

Answer:

There is no explicit requirement in ISO 9001:2015 to document procedures for any process. When it comes to requirements for documentation, the standard requires organization to:
a) maintain documented information to support the operation of its processes;
b) retain documented information to have confidence that the processes are being carried out as planned.

This means that he company can decide whether it needs a documented procedure, flowchart or any other document to ensure that the process is carried out as planned but it doesn't mean that you need documented procedure for any process in the QMS. The good rule of thumb when it comes on deciding whether the documented procedure is needed is to consider whether such procedure would prevent occurrence of nonconformities. If it does, then you should document a procedure, if not, then the docume nted procedure is redundant.
