ITIL® 4 vs ITIL® (Version 5): Side-by-Side Comparison of Key Differences

With ITIL® (Version 5) now available, many professionals want a clear, structured comparison of what has actually changed from ITIL® 4.

This article provides a detailed side-by-side reference covering key concepts, models, and structural changes — designed to help you understand the differences quickly and plan your next steps with confidence.

For an overview of what ITIL® (Version 5) is and why it evolved, see our companion article: ITIL® (Version 5) Is Here: What’s New and Why It Matters

The Core Message: Evolution, Not Revolution

ITIL® (Version 5) builds directly on ITIL® 4. The fundamental concepts, guiding principles, and 34 management practices remain intact. What changes is how the framework is scoped, structured, and applied — reflecting the reality that organizations today manage digital products and services together, in increasingly AI-influenced environments.

Key Concepts: ITIL® 4 vs ITIL® (Version 5)

The table below compares how key ITIL® concepts have evolved.
Concept ITIL® 4 ITIL® (Version 5)
Framework Scope IT Service Management (full lifecycle of IT services) and Digital Transformation ITSM and Service Management, expanded to Digital Product and Service Management (full lifecycle of digital products and services)
Digital Products & Services Not specifically defined New specific definitions covering the full spectrum: non-digital products enabled by technology, technology-enabled products, and fully digital products
Key Roles in Value Co-creation Service providers and service consumers Product vendors, service providers, and service consumers
Service Quality Characteristics Utility, warranty, experience Utility, warranty, experience, sustainability
Governance Evaluate – Direct – Monitor Evaluate – Direct – Monitor – Engage Stakeholders (aligned with ISO/IEC 38500:2024)
Four Dimensions Four dimensions of service management; external PESTLE factors Four dimensions of Product and Service Management; PESTLE factors; ITIL AI Capability Model added to Information & Technology dimension
Guiding Principles Seven Guiding Principles Same seven principles; descriptions clarified; AI guidance added to each
Practices 34 practices in 3 groups: General, Service, Technical Same 34 practices in 2 groups: General, and Product & Service Management
Value Streams Basic definitions Clarified definitions; better link to value chain; value stream mapping guidance in appendix
Service Consumer RolesSponsor, Customer, UserUnchanged
Service RelationshipsBasic, cooperative, collaborative (partnership)Unchanged
Service InteractionsAccess to resources, transfer of goods, service actionsUnchanged; key role of access to resources for digital services is emphasized

Key Models: ITIL® 4 vs ITIL® (Version 5)

Beyond concepts, several core ITIL® models have been updated or introduced. Here is how they compare.
Model ITIL® 4 ITIL® (Version 5)
Product & Service Lifecycle Not present NEW: Unifies digital product and service in one lifecycle model. Activities: Discover, Design, Acquire, Build, Transition, Operate, Deliver, Support
Value Chain Service Value Chain at the centre of the SVS. Activities: Plan, Engage, Design & Transition, Obtain/Build, Deliver & Support, Improve Value Chain with 8 activities linked to the lifecycle model, presented as stepping stones. Each activity uniformly described and mapped to practices
Value System ITIL Service Value System: Guiding Principles, Governance, Service Value Chain, Practices, Continual Improvement ITIL Value System: same 5 components, renamed (Service Value Chain → Value Chain). Strengthened with clearer modular value chain model
Continual Improvement 7 steps. Step 6: “Did we get there?” Step 7: “How do we keep the momentum going?” 7 steps (updated). Step 6: “Are we getting there?” Step 7: “How do we keep the improvements relevant?” All steps described from “clear” and “discovery” perspectives
Service Journey Model Describes steps of the service journey and key tasks of consumer and provider Unchanged; brief explanation of the journey shared by providers and consumers
AI Capability Model Not present NEW: Describes AI’s key functional capabilities within the framework

Continual Improvement Model: Step-by-Step Comparison

Step ITIL® 4 ITIL® (Version 5)
1 What is the vision? What is the vision?
2 Where are we now? Where are we now?
3 Where do we want to be? Where do we want to be?
4 How do we get there? How do we get there?
5 Take action Take action
6 Did we get there? Are we getting there?
7 How do we keep the momentum going? How do we keep the improvements relevant?
The updated wording in steps 6 and 7 reflects a shift from checking whether you have arrived at a destination, to checking whether you are still heading in the right direction. All steps are now described from both “clear” and “discovery” perspectives, recognizing that experimentation is often needed when the path or destination is uncertain.

What About the Certification Structure?

The qualification scheme has also been restructured. For a complete overview of the ITIL® (Version 5) certification pathway, designations, and transition routes, see our dedicated guide:

Final Thoughts

ITIL® (Version 5) is a deliberate, well-structured evolution of ITIL® 4. The core is preserved. The scope is expanded. The models are refined to reflect how organizations actually manage digital products and services today.
For professionals holding ITIL® 4 certifications, your knowledge carries forward. For those starting fresh, ITIL® (Version 5) provides the most complete and up-to-date starting point available.
