What is a gap analysis for ISO 9001, 14001, 45001? A gap analysis involves the comparison of actual performance with potential or desired performance. If an organisation does not make the best use of current resources, or forgoes investment in capital or technology, it may produce or perform below an idealised potential. The reason to perform to ISO 9001, 14001 or 45001 is that these are now the benchmark performance expectations that Global good governance expects. So to establish current performance, use the Standards’ requirements to define the expected performance.  Against each clause rate your own organisation either yes or no, or better still use the plan do check act (PDCA) scale so you can better understand how much further improvement is required to reach the compliance level. For these standards that level will be if you have reached the check step.  In other words your performance is being checked and any continual improvement actions identified in the management review. That will provide a gap analysis for ISO 9001 14001 45001 and provide the basis for an action plan for implementation of an integrated management standard.
