The standard says inputs and outputs must be determined as well as sequence and interaction, but no standard I have yet seen contains the words "process" and "map" next to each other. Over the years people have trained themselves and each other to think a process map is the only thing a CB will accept.
I agree. Even ISO/TS 9002:2016 in section 4.4.1b mentioned a simpler approach:
when determining the sequence and interaction of these processes, the links with the inputs and
outputs of the previous and subsequent processes should be considered; the methods for providing
details of the sequence and interaction of the processes depends on the nature of the organization;
different methods can be used, such as retaining or maintaining documented information (e.g.
process maps or flow diagrams), or a more simple approach, such as a verbal explanation of the
sequence and interaction of the processes
The ISO 9001 Auditing Practices Group Guidance by the ISO and the International Accreditation Forum have also provided guidance for CBs in
Evidence Collection:
Auditors should be aware that objective evidence does not necessarily depend on the
existence of documented information, except where specifically mentioned in ISO 9001. In
other cases is up to the organization to determine what documented information is
necessary in order to provide this objective evidence.
It is the organization’s responsibility to provide objective evidence of conformity.
Organizations may be able to demonstrate conformity without the need for extensive
documented information.
