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 PeopleCert released ITIL (Version 5) in early 2026. The natural question is: what exactly changed, and do I need to start over? The short answer is no. ITIL 5 is an evolution of ITIL 4, not a complete rewrite. The guiding principles, the four dimensions and value co-creation all carry over, and most of the new material sits around the lifecycle model and AI.

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 4 was framed around IT service management. PeopleCert now positions ITIL (Version 5) as guidance for managing digital products and services, and "digital product and service management concepts" is the first topic on the Foundation syllabus.

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 Product and Service Lifecycle Model, which PeopleCert describes as eight activities that apply to every product and service:

• 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: "Product and service lifecycle" is one of the nine Foundation syllabus topics, so learn all eight 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 history, AI governance is built into the framework rather than bolted on. PeopleCert describes Version 5 as AI-native, and it has released a separate ITIL AI Governance (Version 5) extension module, which has no prerequisite and sits outside the main designations.

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. That is why each of the six capabilities carries its own risks and controls, and why the deeper governance material sits in the AI Governance module rather than in Foundation.

Exam Tip: The 6C Model is new to ITIL 5. At Foundation level, be able to name all six capabilities and say 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 management practices - ITIL 5 keeps 34 management practices, including incident management, problem management, change enablement, and service request management
• The value system - the model that connects governance, practices and the lifecycle still exists, renamed the ITIL Value System, with updated components
• 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:

ITIL Foundation exams use 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. If you hold ITIL 4, the old value chain activities are a common distractor, and our ITIL 5 Foundation sample questions show how that trap is set.

Exam Tip: Answer every question, even if you are uncertain. A blank scores zero, while a guess among four options gives you a 25% chance.

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 (our ITIL 5 certification path guide covers which one to pick). The updated qualification scheme includes:

• ITIL Foundation (Version 5) - the entry point
• ITIL Practice Manager - for operational practitioners. The Version 5 Practice modules are not released yet, so the Practice requirement is currently met with an ITIL 4 Practice module
• ITIL Managing Professional - for service owners, product managers and delivery leads
• ITIL Strategic Leader - for senior leaders and decision-makers
• ITIL Master - awarded for holding all three designations above

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 (20 questions, 30 minutes, 65% pass mark) that covers only the key changes at Foundation level. PeopleCert lists the UK exam bundle at £199, against £541 for the full Foundation.
2. Skip the bridge and go straight to higher-level Version 5 modules - ITIL 4 qualifications count as prerequisites for the higher-level Version 5 modules, so the bridge is optional.

Certificate Validity

ITIL Version 5 certificates are valid for three years, renewed with 60 CPD points or by passing another exam in the suite. Plan your continuing professional development accordingly. PeopleCert also plans to sunset every ITIL 4 module on 31 December 2027; we cover what that means for an exam booking or an existing certificate in ITIL 4 Is Retiring on 31 December 2027.

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. Foundation tests awareness of the six capabilities, so learn each name and what it does.

4. Practise With Realistic Questions

Foundation tests recall and understanding, but questions often describe a short situation and ask which principle or activity it shows. 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.
