Integrated implementation

Answer: For information about ISO 27001 and ISO 9001 integration, I suggest you to see these materials:
- Using ISO 9001 for implementing ISO 27001 https://advisera.com/27001academy/blog/2010/03/08/using-iso-9001-for-implementing-iso-27001/

2 - Additionally, can you tell me what would trigger a re-audit by an ISO auditor? After our initial audit and certification, do we need to be re-audited every time we update to a new version of a document that is part of the ISMS?

Answer: As part of the certification process, the certification body plans surveillance audits to b e performed periodically after a successful certification audit (normally they are performed annually), so there is no need to perform a re-audit every time the ISMS is updated. Another event that may trigger an additional audit is if the certification body receives a complaint from an organization's customer reporting a significant failure on the organization's ISMS.
