Hi Sarah, good on you for raising this. I am currently doing some work for an SME who are TELARC audited and who had their IMS rewritten by a consultant to match what the auditor wanted to see. It took me sometime to understand why the IMS started at section 4. I am now in the process of unpicking this, maintaining the structure of the 3 ISO standards but ensuring it fits the character of the business. Incidentally there was nothing wrong with their original system. The IMS (or HSE MS) should be written to fit the business (with certification requirements considered of course and application of ISO) not the system written to fit the standards. Those that are familiar with Safety Cases and the addition of concordance tables understand that there is a simple way of providing an auditor a map to navigate a companies system. As HSE consultants we should be aware of the needs of the business we are supporting. If we are doing this right there should be no issues for an energetic auditor to find their way. I would say push back on the re-write but ensure the original management system has a road map to match it's contents to ISO 45001 so the auditor doesn't get lost.........
