ITIL 4 and ITIL Version 5 Compared

| Technical practices | Three separate practices | Merged into Product & Service practices |
| Experience | Referenced across modules | Dedicated publication (ITIL Experience) |
| Strategy | Strategy Management practice | ITIL Strategy publication + VUCA model |
| Transformation | No dedicated module | ITIL Transformation (new model) |

Changes in Detail
1. From Service Value Chain to Product & Service Lifecycle
ITIL 4 employed the Service Value Chain with six activities: Plan, Improve, Engage, Design & Transition, Obtain/Build, Deliver & Support
ITIL v5 introduces the Product & Service Lifecycle with eight stages: Discover, Design, Acquire, Build, Transition, Operate, Deliver, Support
A distinguishing feature: the new lifecycle applies to both products and services, with separate guidance provided from product vendor and service provider perspectives.
2. Restructuring Management Practices
ITIL 4 structure:
- 14 General Management Practices
- 17 Service Management Practices
- 3 Technical Management Practices
ITIL v5 structure:
- 12 General Management Practices
- 22 Product & Service Management Practices
- (Technical Management Practices merged in)
Five practices that changed group:
- Deployment Management (Technical → Product & Service)
- Infrastructure and Platform Management (Technical → Product & Service)
- Software Development and Management (Technical → Product & Service)
- Information Security Management (General → Product & Service)
- Service Financial Management (General → Product & Service)
3. AI-Native Framework
ITIL 4 lacked integrated AI guidance. ITIL v5 treats AI as fundamental:
- AI is assumed in use and embedded throughout service design, testing, and operations
- AI Governance functions as a dedicated publication
- Human-AI collaboration models are incorporated
- AI risk and opportunity assessment is included
- AI is woven into management practices (with updates scheduled for H2 2026)
4. Experience-Driven
ITIL 4 discussed value but lacked detailed experience guidance. ITIL v5 introduces:
- ITIL Experience as a dedicated publication
- Service journey mapping from organizational and individual perspectives
- Employee experience as a leading indicator of customer experience
- Experience mapped to the new value chain
5. Complexity-Native and VUCA Strategy
ITIL 4 included Strategy Management but was not optimized for VUCA environments. ITIL v5 adds:
- ITIL Strategy as a dedicated publication
- Planning and execution models for strategic contexts
- Optimization for complexity scenarios
- Progressive, adaptable guidance
- Integration with the Transformation model
6. Transformation Model
New to ITIL v5:
- Complexity-driven transformation model
- Contextual, phased guidance
- Governance, initiation, and execution patterns
- A comprehensive toolkit of methods and techniques
Summary: Should You Upgrade?
Short answer: Yes, but migration does not require urgency.
- ITIL 4 knowledge provides a solid foundation
- ITIL v5 represents evolution, not displacement
- Management practices will roll out progressively through H2 2026
- Organizations adopting AI or managing digital products will gain immediate value from ITIL v5
