ISO 22301 vs ISO 22313: Requirements and Guidance Explained

ISO 22301 and ISO 22313 address the same business continuity management system, but they do different jobs. ISO 22301 specifies requirements. ISO 22313 explains and recommends ways to understand and apply those requirements. Organisations can use both, yet certification and nonconformity decisions must remain anchored to applicable requirements rather than optional guidance.

Direct answer: Use ISO 22301 to determine what a conforming BCMS must achieve and what an auditor can assess. Use ISO 22313 to understand intent, consider implementation approaches and improve effectiveness. ISO 22313 does not add mandatory requirements and is not the certification basis for ISO 22301.

Current editions in October 2026

The current published requirements standard is ISO 22301:2019, together with Amendment 1:2024. ISO has also started work on a future third edition, but the committee draft is not a published replacement.

The current published guidance is ISO 22313:2020. ISO records show that it was reviewed and confirmed in 2025, so it remains current. A new edition is under development and is intended to replace it when published.

ISO’s official pages provide the current status for ISO 22301:2019 and ISO 22313:2020. Check those records when planning an update. Draft projects can help with horizon scanning, but organisations and auditors should not quietly treat draft wording as current requirements.

The essential difference

Dimension	ISO 22301	ISO 22313
Type	Requirements standard	Guidance and recommendations
Primary question	What must a conforming BCMS achieve?	How can the requirements be understood and applied?
Certification	Used as the conformity and certification basis	Not a certification basis for ISO 22301
Language effect	Mandatory where a requirement applies	Advisory and explanatory
Audit use	Source of audit criteria	Interpretive support and improvement ideas
Tailoring	Requirements apply according to scope and context	Recommendations are selected according to need
Relationship	Defines the management system	Follows and supports the requirements structure

The guidance should not be described as a “weaker version” of the requirements. It serves a different purpose. Nor should an organisation claim conformity with every example or recommendation merely because it purchased the publication.

What ISO 22301 governs

ISO 22301 uses a management-system structure covering organisational context, leadership, planning, support, operation, performance evaluation and improvement. It connects business continuity policy and objectives with impact analysis, risk assessment, strategies, solutions, plans, exercises, monitoring, audit, review and corrective action.

The standard does not prescribe one organisation chart, recovery technology or document set for every business. Requirements are generic so that the BCMS can fit different sectors, sizes and operating environments.

The business continuity policy guide shows how leadership direction becomes an auditable governance layer without reproducing standard text.

What ISO 22313 contributes

ISO 22313 provides recommendations and explanation for applying ISO 22301. It can help teams:

• understand the intent behind a concise requirement;
• consider factors relevant to scope and context;
• design governance and planning activities;
• improve business impact and risk work;
• develop continuity strategies and arrangements;
• plan exercising, evaluation and improvement; and
• adapt the approach to organisational complexity.

Guidance is useful when the requirements tell the organisation what outcome is needed but leave multiple valid ways to achieve it. The team should evaluate recommendations against its own context rather than copy them into procedures.

How to use both during implementation

Use a four-column implementation record:

Column	Question
Requirement	Which ISO 22301 obligation is being addressed?
Context	What scope, risk, interested party or operating condition shapes it?
Design	Which process, role, control or record will achieve the outcome?
Guidance considered	Which ISO 22313 recommendations informed the design, and what was tailored?

This preserves the line between requirement and design choice. It also helps the organisation explain why a recommendation was adopted, changed or not relevant.

For example, the requirement may call for continuity objectives. ISO 22313 can help the team consider practical implementation. The organisation still defines its own objective hierarchy, measures, owners and reporting based on business need. The continuity objectives guide provides an original implementation method.

How auditors should use the guidance

Audit criteria must be agreed and traceable. For an ISO 22301 conformity audit, a nonconformity should identify the applicable requirement and objective evidence. An auditor can use ISO 22313 to understand possible implementation approaches or formulate questions, but should not raise a nonconformity merely because the organisation chose another effective method.

An internal audit may deliberately include selected ISO 22313 recommendations in its criteria if management has adopted them through policy, procedure, contract or programme commitment. In that case, state the additional criterion clearly.

Example

An auditor observes that the organisation uses a department-based activity model. ISO 22313 may support exploration of context and dependencies, but the model is not automatically nonconforming because a process-based method might be preferable. The auditor should test whether activities, impacts, dependencies and recovery arrangements satisfy the relevant requirements and work in practice.

The activity-definition guide explains how to evaluate that outcome.

Avoid five common mistakes

1. Treating every recommendation as mandatory

This inflates scope, creates unnecessary records and produces invalid audit findings. Preserve the source and force of each criterion.

2. Using guidance without the requirements

Guidance can improve understanding but does not replace access to ISO 22301 when the organisation is implementing or auditing conformity.

3. Copying standard text into internal documents

Internal documents should explain the organisation’s own processes, authority and evidence. Reproducing copyrighted text is unnecessary and can make procedures difficult to use.

4. Citing an edition without checking status

ISO 22313:2012 is withdrawn and replaced by the 2020 edition. Current published editions should be controlled, and future drafts should be tracked separately.

5. Claiming that guidance proves implementation

A standards library is not operating evidence. Auditors need completed analysis, approvals, exercise results, decisions, logs and verified actions.

Connect the standards to ISO 27001

ISO 22301 and ISO/IEC 27001 share management-system concepts, making coordinated governance possible. ISO 27001 addresses information-security risk and includes continuity-related Annex A controls; ISO 22301 addresses the broader organisational continuity management system.

Shared evidence can include context, competence, document control, internal audit, management review and improvement. Operational evidence may also overlap where ICT recovery supports prioritised activities. Keep scopes, objectives and statements of conformity distinct.

The ISO 22301 and ISO 27001 continuity guide explains this relationship. The integrated internal audit guide shows how to coordinate assurance without losing standard-specific criteria.

Use the free ISO 27001 Clause Explainer for practical context on the ISMS. It does not reproduce or replace either business continuity standard.

Build an edition and guidance register

For each external standard, record:

• exact title, edition and amendment;
• publication status and last verification date;
• licensed access location;
• purpose and scope of use;
• owner responsible for monitoring change;
• internal processes or documents informed;
• adopted recommendations or stated commitments;
• transition assessment; and
• next review trigger.

When a new edition is published, perform a controlled gap assessment. Do not update citations alone. Determine which requirements, guidance, processes, competence, evidence and certification transition arrangements are affected.

Sample audit questions

• Which document is the approved conformity criterion?
• Is the organisation using the current published edition and amendment?
• Where has ISO 22313 informed design decisions?
• Has any recommendation become mandatory through internal policy or contract?
• Can each nonconformity be traced to an applicable requirement?
• Are future drafts separated from current obligations?
• Does operating evidence show that the chosen method works?

Judge pass, partial and fail conditions

Pass: Editions and purposes are controlled, requirements and recommendations are distinguished, guidance is tailored to context, audit findings cite valid criteria and operating evidence demonstrates effectiveness.

Partial: The correct publications are available, but procedures mix requirement and guidance language, adopted recommendations are not tracked or draft changes are poorly governed.

Fail: A withdrawn edition drives the BCMS, ISO 22313 recommendations are raised as ISO 22301 nonconformities without an adopted criterion, or standards are cited while required processes do not operate.

ISO 22301 and ISO 22313 work best as a pair: one establishes the auditable requirements, and the other helps organisations make implementation choices that are practical, proportionate and effective.
