The latest business continuity news from around the world

ISO has published an updated version of ISO/TS 22317, ‘Security and resilience - Business continuity management systems - Guidelines for business impact analysis’. The new ISO/TS 22317:2021 replaces ISO/TS 22317:2015, which has now been withdrawn.

ISO/TS 22317:2021 gives guidelines for an organization to implement and maintain a formal and documented business impact analysis (BIA) process appropriate to its needs. It does not prescribe a uniform process for performing a BIA.

According to ISO/TS 22317:2021 the key differences in the updated version are:

  • The document has been updated to align with ISO 22301:2019;
  • The document structure has been updated to improve the description of the business impact analysis process;
  • More focus has been placed on the BIA process and less on the business continuity programme;
  • BIA and the BIA process have been clearly differentiated;
  • BIA process roles have been consolidated to BIA leader and activity owners;
  • The section ‘Initial BIA considerations’ has been removed and the guidance redistributed;
  • The section ‘Strategy selection’ has been removed as it is part of ISO/TS 22331;
  • The annex on terminology has been removed;
  • The annex on BIA information collection methods has been enhanced;
  • A new annex with examples for performing a BIA has been included.
