ITIL 5 vs ITIL 4: What's Changed?

What Has Changed in ITIL 5?

If you hold an ITIL 4 certification or you are just beginning your ITIL journey, you have probably heard that ITIL Version 5 landed in February 2026. The natural question is: what exactly changed, and do I need to start over? The short answer is no, you do not need to start over. ITIL 5 is an evolution of ITIL 4, not a complete rewrite. According to PeopleCert, the framework retains roughly 40% of ITIL 4 content unchanged, introduces 36% entirely new material, and enhances or updates the remaining 24%.

That said, the changes are significant. ITIL 5 brings AI governance into the core of the framework, replaces the six-activity Service Value Chain with an eight-activity Product and Service Lifecycle Model, and formally shifts the scope from IT Service Management to Digital Product and Service Management. If you are preparing for the ITIL 5 Foundation exam, understanding these differences is essential.

From IT Service Management to Digital Product and Service Management

One of the most visible changes is the expanded scope. ITIL no longer stands for "IT Infrastructure Library." The framework now describes itself as "a framework and best practice guidance for digital product and service management."

This is not just a rebrand. ITIL 4 introduced value co-creation and service value streams, but ITIL 5 takes this further by treating products and services as two sides of the same lifecycle. Organisations today do not just manage services in isolation. They manage digital products that deliver multiple services to multiple user groups. ITIL 5 acknowledges this reality and provides guidance that maps to how modern teams actually work.

What This Means for Exam Candidates

If you are studying for the Foundation exam, expect questions that frame scenarios around product and service management rather than service management alone. The language has shifted, and the exam reflects that shift.

The New ITIL Value Chain: 8 Activities

ITIL 4 introduced the Service Value Chain (SVC) with six core activities:

• Plan
• Improve
• Engage
• Design and Transition
• Obtain/Build
• Deliver and Support

ITIL 5 replaces this with the ITIL Value Chain, built around a Product and Service Lifecycle Model (PSLM) containing eight activities:

• Discover - identifying needs and opportunities
• Design - designing solutions to meet those needs
• Acquire - sourcing components and resources
• Build - creating or configuring solutions
• Transition - moving solutions into live operation
• Operate - running and maintaining live services
• Deliver - ensuring value reaches consumers
• Support - resolving issues and fulfilling requests

Exam Tip: The ITIL 5 Foundation exam tests your understanding of all eight value chain activities. Know each activity's purpose and how they relate to one another. The value chain is iterative, not linear, so teams can move between activities based on what the work requires.

Why the Change?

The six-activity SVC in ITIL 4 was sometimes criticised for being too abstract. The eight-activity model maps more clearly to how Agile and DevOps teams work in practice. Activities are combined dynamically to form value streams, and teams pull only the specific activities needed for a particular situation.

AI Governance and the 6C Model

This is the headline change. For the first time in ITIL's 40-year history, AI governance is embedded directly into the framework rather than bolted on as an afterthought. ITIL 5 introduces a dedicated AI Governance extension module, the only extension module in the entire ITIL 5 qualification scheme, scheduled for release in May 2026.

The 6C Model

At the heart of ITIL 5's approach to AI is the 6C Model (also called the ITIL AI Capability Model). It classifies AI solutions into six core capabilities:

1. Creation - generating new content, code, or documentation
2. Curation - improving the quality and relevance of existing data
3. Clarification - helping users navigate and understand complex information
4. Cognition - identifying patterns and hidden insights for proactive problem detection
5. Communication - natural interfaces such as chatbots and intelligent virtual assistants
6. Coordination - autonomous execution and orchestration of actions across systems

The 6C Model helps organisations map AI capabilities against risk profiles, controls, and countermeasures. It provides a structured way to evaluate both the value and the risks that AI introduces into service management.

Why Traditional IT Governance Falls Short for AI

ITIL 5 makes a critical distinction: traditional IT governance is insufficient for AI. A compliant IT system will generally remain compliant when audited the following year. An AI system might fail to be compliant even minutes after going live, because its behaviour can drift as it processes new data. This is why ITIL 5 introduces four governance perspectives specifically for AI:

• Decision Authority and Risk Management
• Ethical Principles and Responsible AI
• Data Governance and Performance Management
• Regulatory Compliance and Operational Standards

Exam Tip: The 6C Model is new to ITIL 5 and is a high-priority topic for the Foundation exam. Be able to name all six capabilities and explain what each one does in a service management context.

What Stayed the Same in ITIL 5?

Not everything changed. ITIL 5 builds on the foundations that ITIL 4 established, and several core elements remain intact:

• The Seven Guiding Principles - Focus on value, Start where you are, Progress iteratively with feedback, Collaborate and promote visibility, Think and work holistically, Keep it simple and practical, and Optimise and automate
• The 34 Management Practices - all 34 practices from ITIL 4 carry forward, including incident management, problem management, change enablement, and service request management
• The Service Value System (SVS) - the overall model that connects governance, practices, and the value chain still exists, though its components have been updated
• Value co-creation - the principle that value is created through active collaboration between service providers and consumers remains central

If you already hold ITIL 4 Foundation, you have a strong base. The new material adds to what you know rather than replacing it entirely.

ITIL 5 Foundation Exam: Format and Requirements

The ITIL Foundation (Version 5) exam is the entry point for the updated certification scheme. Here are the key details:

The exam uses four question types: standard multiple-choice with four options, negative questions (which option is NOT correct), missing-word questions, and list-based questions where you select two correct statements from four.

Exam Tip: There is no negative marking on the ITIL 5 Foundation exam. Always answer every question, even if you are uncertain. A guess gives you a 25% chance; a blank gives you zero.

ITIL 5 Certification Pathway and Transition Options

For New Candidates

If you are starting fresh, the path is straightforward: take the ITIL Foundation (Version 5) exam and then progress to higher-level modules. The updated qualification scheme includes:

• ITIL Foundation (Version 5) - the entry point
• ITIL Practice Manager (Version 5) - for operational practitioners
• ITIL Managing Professional (Version 5) - for IT managers and team leads
• ITIL Strategic Leader (Version 5) - for senior leaders and decision-makers
• ITIL Master (Version 5) - the highest level of ITIL certification

For Existing ITIL 4 Certificate Holders

If you already hold ITIL 4 Foundation, you have two options:

1. Take the ITIL Foundation Bridge (Version 5) - a shorter exam that covers only the key changes introduced at Foundation level. This is the quickest and most cost-effective route to updating your certification.
2. Skip the bridge and go straight to higher-level Version 5 modules - PeopleCert has confirmed that ITIL 4 qualifications remain valid prerequisites for higher-level Version 5 certifications. The bridge is optional, not mandatory.

Certificate Validity

One important change: ITIL Version 5 certificates are issued with a three-year renewal date. This is a shift from ITIL 4, where Foundation certificates did not expire. Plan your continuing professional development accordingly.

How to Prepare for ITIL 5

Whether you are taking the full Foundation exam or the Bridge module, here is a practical study plan:

1. Understand What Has Changed

Start by learning the differences between ITIL 4 and ITIL 5. Focus on the three headline changes: the expanded scope to digital product and service management, the eight-activity ITIL Value Chain, and AI governance with the 6C Model.

2. Master the 34 Practices

All 34 management practices carry forward from ITIL 4. If you already know them, refresh your memory. If you are new to ITIL, these form the bulk of the exam content. Key practices to prioritise include incident management, problem management, change enablement, service level management, and service request management.

3. Learn the 6C Model Inside Out

This is entirely new material with no ITIL 4 equivalent. Expect multiple exam questions on the six AI capabilities and their practical applications.

4. Practise With Realistic Questions

The exam uses scenario-based questions that require you to apply ITIL concepts, not just recall definitions. Practising with realistic exam questions is the most effective way to prepare. CertCrush offers ITIL 5 Foundation practice exams that mirror the format and difficulty of the real thing.

5. Time Your Practice Sessions

With 40 questions in 60 minutes, you have 90 seconds per question. That is enough time to read carefully, but not enough to deliberate for long. Build your exam pace during preparation.
