9001:2026
Key changes

ISO 9001:2015 vs ISO 9001:2026

A practitioner-focused side-by-side of the published 2026 edition. Twelve changes, ordered by how much work each one creates, with what to do about each.

NewExpandedClarified

Quality culture and ethical behaviour

New
2015

Absent. The words appear nowhere in the requirements.

2026

A shall in the leadership clause. Top management promotes quality culture and ethical behaviour, people must be aware of it, and it is recognised as influencing the working environment.

Risks and opportunities

Expanded
2015

A single clause 6.1, with opportunities treated as a by-product of risk.

2026

Split into 6.1.1, 6.1.2 risks and 6.1.3 opportunities. Opportunities get their own determine, analyse, evaluate and act requirements.

Interested party requirements

New
2015

Determine relevant interested parties and their relevant requirements.

2026

Adds a third step: determine which of those requirements will be addressed through the QMS.

Management of change (Cl. 6.3)

Expanded
2015

Four considerations when changing the QMS.

2026

Seven. Adds communication of the change, how effectiveness will be monitored and evaluated, and how results will be reviewed.

Leadership (Cl. 5.1.1)

Expanded
2015

Ten leadership obligations, with accountability listed first.

2026

Twelve. Adds quality culture and ethical behaviour, separates the process approach from risk-based thinking, adds opportunity-based thinking, and moves accountability to the last item.

Roles and reporting (Cl. 5.3)

Expanded
2015

Five assigned responsibilities, under "Organizational roles, responsibilities and authorities".

2026

Six, under "Roles, responsibilities and authorities". Reporting splits into QMS performance and improvement opportunities.

Organizational knowledge (Cl. 7.1.6)

Expanded
2015

Knowledge maintained and made available, to achieve conformity of products and services.

2026

Knowledge retained, applied and shared, to achieve the intended results of the QMS. A new note lists four forms knowledge can take.

Analysis and management review

Expanded
2015

Six analysis inputs; management review inputs combine risk and opportunity.

2026

Eight analysis inputs. Risk action effectiveness and opportunity action effectiveness are evaluated separately, in both 9.1.3 and 9.3.2. Management review adds changes in interested party needs and expectations.

Improvement structure (Cl. 10)

Clarified
2015

10.1 General, 10.2 Nonconformity, 10.3 Continual improvement.

2026

10.1 and 10.3 merge into a single 10.1 Continual improvement. There is no clause 10.3.

Terms and definitions (Cl. 3)

New
2015

Refers to ISO 9000 for all terms.

2026

Core terms are brought into Clause 3 of the standard itself.

Annexes

Expanded
2015

Annex A on structure and terminology, Annex B on other ISO quality management standards.

2026

Annex A is enhanced, including guidance on applicability and on words such as appropriate, applicable, consider and ensure. Annex B is removed.

Climate change

Clarified
2015

Not in the original text. Added by Amendment 1:2024.

2026

Carried through unchanged. Determine whether climate change is a relevant issue, plus a note that interested parties can have climate-related requirements.

The twelve changes in detail

One card per change, in the same order as the table: what changed, the clauses involved, and what to do about it.

01Quality culture and ethical behaviour

New

This is the headline change of the edition and it is a shall, not a note. The standard also defines it: an organization's quality culture and ethical behaviour are reflected in its shared values, attitudes, practices and actions. Reflected in, not consists of, which is what makes it auditable.

Clauses: 5.1.1 i) and Note 2, 7.1.4, 7.3 e). Guidance in Annex A.5.1 and A.7.3, which point to ISO 10010 and ISO 10018.

What to do: Expect interviews rather than document review. Be ready with dated examples of how top management promotes it, and check that people at any level can say what it means here in their own words.

02Risks and opportunities

Expanded

The largest structural change. Risk and opportunity are now separate disciplines with parallel requirements. Risk actions must be proportionate to potential impact; opportunity actions must be appropriate to context and support desired results. Annex A.6.1.2 confirms this does not imply formal risk management methods.

Clauses: 6.1.1, 6.1.2, 6.1.3. Flows through to 9.1.3 e) and f) and 9.3.2 g) and h).

What to do: A combined register with the opportunity column left empty is now a likely finding. Separate the two, and evidence that opportunity actions were evaluated for effectiveness.

03Interested party requirements

New

Clause 4.2 gains item c): determine which of these requirements will be addressed through the quality management system. Small wording, useful effect. It gives you a documented basis for deciding that a requirement sits outside the QMS, which the 2015 text did not.

Clauses: 4.2 c). Annex A.4.2 adds that climate expectations can influence interested party requirements.

What to do: Add a column to your interested party register recording whether each requirement is addressed through the QMS, and why.

04Management of change

Expanded

Clause 6.3 grows from four considerations to seven. Item b) becomes the potential impact on the integrity of the QMS, item c) adds information alongside resources, and three new items cover communicating the change, monitoring and evaluating its effectiveness, and reviewing the results.

Clauses: 6.3. Annex A.6.3 points to ISO/TS 10020 on organizational change management.

What to do: A change record that stops at approval is no longer enough. Show the change was communicated, its effectiveness evaluated, and the results reviewed.

05Leadership

Expanded

The list in 5.1.1 goes from ten items to twelve. New item i) is promoting quality culture and ethical behaviour. Items j) and k) split what was one item, and k) now covers opportunity-based thinking as well as risk-based thinking. Accountability moves from a) to l). Promoting improvement becomes promoting continual improvement.

Clauses: 5.1.1. Also 5.2.1, which grows from four items to five as context and strategic direction become their own item.

What to do: Map your leadership evidence against all twelve items. Most organizations have nothing on i), j) or k).

06Roles and reporting

Expanded

Clause 5.3 loses the word "Organizational" from its title, and the lead-in drops "and understood". The assigned responsibilities go from five to six, because reporting on QMS performance and reporting on opportunities for improvement are now separate duties.

Clauses: 5.3.

What to do: Check your role descriptions cover all six. The improvement reporting duty is the one usually missing.

07Organizational knowledge

Expanded

Knowledge must now be retained, applied and shared, rather than maintained and made available. The purpose broadens from conformity of products and services to the intended results of the QMS. A new note lists four forms: experience held by people, knowledge from education and training, knowledge embedded in methods and products, and knowledge represented in documented information and digital systems.

Clauses: 7.1.6.

What to do: A knowledge register that nobody reads no longer satisfies the wording. Show knowledge being applied and shared.

08Analysis and management review

Expanded

Clause 9.1.3 grows from six evaluation inputs to eight, separating risk action effectiveness from opportunity action effectiveness and adding the effectiveness of planning implementation. Management review adds changes in the needs and expectations of interested parties, splits risk and opportunity, and 9.3.1 adds alignment with the strategic direction of the organization. Clause 9.3.3 is renamed from outputs to results.

Clauses: 9.1.3, 9.3.1, 9.3.2, 9.3.3. Also 9.2.2, which adds audit objectives and the word correction.

What to do: Update your management review agenda template. Three inputs are new or split.

09Improvement structure

Clarified

The 2015 clauses 10.1 General and 10.3 Continual improvement merge into a single 10.1 Continual improvement. Clause 10.2 on nonconformity and corrective action is substantively unchanged.

Clauses: 10.1, 10.2. There is no 10.3.

What to do: Renumber any procedure, matrix or internal audit checklist that still references clause 10.3.

10Terms and definitions

New

Clause 3 now carries the core terms rather than referring wholesale to ISO 9000. Annex A.2 also clarifies the meaning of appropriate versus applicable, consider versus take into account, continual versus continuous, ensure, and the difference between "shall be available as documented information" and "documented information shall be available as evidence of".

Clauses: Clause 3, Annex A.2.

What to do: The available versus evidence distinction decides whether you need a live document or a retained record. Worth reading before your next audit.

11Annexes

Expanded

Annex A is expanded with new material on applicability, terminology, and clause-by-clause clarification. Annex A.5.1 and A.7.3 both point to ISO 10010 on organizational quality culture, A.7.3 also points to ISO 10018 on people engagement, A.6.1.2 confirms formal risk management is not implied, and A.6.3 points to ISO/TS 10020. Annex B, which listed other ISO quality management standards, is removed.

Clauses: Annex A. Annex B removed.

What to do: Annex A is informative, but it is where the drafters explain what they meant. Read A.2 and A.3 in particular.

12Climate change

Clarified

Climate change was not in the original 2015 text. It was added by Amendment 1:2024 and carried into the 2026 edition unchanged. It reads as a standalone sentence, not as a qualifier inside the issues requirement: the organization shall determine whether climate change is a relevant issue.

Clauses: 4.1, and a note under 4.2. Annex A.4.2 expands on it.

What to do: If you already implemented Amendment 1:2024, nothing changes. If not, record a determination either way. A yes or no with reasoning is enough.
