A Process Map is simply one way to provide a top-level view of the system documentation required for a typical a ISO 9001 quality management system. You don’t have to use process maps to be compliant with ISO9001, but they are a very effective visualisation tool for the job.
Process Maps can be easily extended when organisations seek additional certification to AS4801 / ISO 14001 / HACCP . The Process Map will in these cases provide an overview of the integrated management system.
Clause 4.1, “General requirements of the ISO 9001 Standard” states that:
The organisation shall:
a) determine the processes needed for the quality management system and their application throughout the organisation,
b) determine the sequence and interaction of these processes
Note 1 of this clause says that you will need to include your processes for:
The Standard contains a generic model of a process-based quality management system that illustrates the process linkages of a typical organisation. However, this model is generally not easily interpreted by organisations.
This map can easily be modified for service based companies or expanded to include safety or other compliance related processes.
