ISO/TS 22317:2015 Societal security - Business continuity managment systems - Guidelines for business impact analysis

This Technical Specification for business continuity management systems provides guidelines (based on good international practice) for performing a business impact analysis (BIA), which is a requirement of ISO 22301 (clause 8.2). It provides guidance for establishing, implementing and maintaining a formal and documented process for business impact analysis. It is applicable to all organizations, regardless of type, location, size and nature of the organization.

This business impact analysis standard provides a framework for determining continuity and recovery priorities, objectives and targets.

The purpose of the business impact analysis process is to analyze the consequences of a disruptive incident on the organization.  The outcome is a statement and justification of business continuity requirements. 

Organizations implementing ISO 22317 will reach the following benefits:

  • Endorsement or modification of the organization's BC programme scope;
  • Identification of legal, regulatory, and contractual requirements (obligations) and their effect on business continuity requirements;
  • Evaluation of impacts on the organization over time, which serves as the justification for business continuity requirements (time and capability);
  • Identification and confirmation of product/service delivery requirements following a disruptive incident, which then sets the prioritized timeframes for activities and resources;
  • Identification of, and establishment of, the relationships between products/services, processes, activities, and resources;
  • Determination of the resources needed to perform prioritized activities (e.g. facilities; people; equipment; information, communication and technology assets; supplies; and financing);
  • Understanding of the dependencies on other activities, supply chains, partners, and other interested parties; and
  • Determination of how up to date the information needs to be.


Brian Zawada (USA), the project leader responsible for writing ISO 22317, explains:

This new technical specification summarizes the guidance necessary to identify appropriate business continuity requirements as part of a broader business continuity management system or program.  Many organizations struggle with identifying when, and to what extent, activities and resources need to be available following a disruptive event.  The ISO 22317 project team feels strongly that this new technical specification will help organizations identify business continuity requirements leading to the implementation of appropriate business continuity strategies.”
