  • ITIL Version 5: What’s New and How It Compares to ITIL 4

    ITIL Version 5 is the latest iteration of the ITIL framework, officially launched in early 2026. This version builds on the foundation of ITIL 4 while introducing meaningful structural enhancements to better support modern digital product and service management. Unlike previous incremental updates, Version 5 reflects a deliberate evolution driven by practical feedback from service management professionals and the realities of AI-enabled business environments.

    Core Evolution from ITIL 4

    1. Unified Product and Service Lifecycle One of the most visible changes in Version 5 is the introduction of a formal Product and Service Lifecycle Model, which defines eight phases: Discover, Design, Acquire, Build, Transition, Operate, Deliver, and Support. This model explicitly unifies the management of digital products and services in a single lifecycle, encouraging alignment across development, delivery, and support activities. It moves beyond the service-centric value chain of ITIL 4 to reflect how organizations now build, operate, and evolve complex digital ecosystems.

    2. AI-Native Design While AI and automation were acknowledged as important enablers in ITIL 4, ITIL Version 5 is AI-native by design. The framework embeds AI-aware guidance throughout its core concepts and includes specific AI Governance content to help organizations adopt AI responsibly, manage risk, and maintain ethical and transparent controls. This makes Version 5 more directly relevant for environments where machine-assisted decision support and automated workflows are integral to business operations.

    3. Stronger Experience and Outcome Focus Experience is now a central concern. Version 5 places emphasis on customer experience, user experience, and employee experience as integral drivers of value, not just operational metrics. The shift encourages organizations to design practices around meaningful outcomes and stakeholder satisfaction, reinforcing value creation across all lifecycle stages rather than merely following process steps.

    What Remains from ITIL 4

    Despite these advances, Version 5 does not discard the core strengths of ITIL 4. Concepts such as value creation, continual improvement, and the importance of governance remain central. The familiar 34 practices from ITIL 4 continue to underpin guidance, though they are reframed to align with the unified lifecycle and digital product focus. Existing ITIL 4 certifications remain valid and can be used as prerequisites for Version 5 modules, with courses like a Foundation Bridge available to ease the transition.

    Why Version 5 Matters

    ITIL Version 5 reflects the reality that most organizations no longer operate with purely IT-centric, siloed service delivery models. Instead, they manage integrated digital products and services supported by automation and AI, where business value, experience, and adaptability are essential. By bringing product and service management together, embedding AI governance, and emphasizing measurable outcomes and experience, Version 5 aims to help organizations remain resilient and competitive in fast-changing environments.

  • What is ITIL? Why does it exist?

    ITIL started as a simple guide for managing IT services and has grown into a complete framework that helps organizations deliver value to their customers. Let’s look at how it has evolved over time.

    Where ITIL Came From

    Back in the 1980s, the UK government needed a better way to manage their computer systems. They created ITIL as a collection of guidelines to make IT services more reliable and cost-effective. The main idea was simple: if you follow standard procedures, you’ll get better results.

    Soon, companies outside the government started using ITIL too. They liked that it wasn’t tied to any specific vendor and gave them a clear roadmap for running their IT departments.

    ITIL Version 2: Focusing on Processes

    Around 2000-2001, ITIL version 2 came out. This update made things much clearer by organizing everything around specific processes. It covered important areas like:

    • Handling incidents when things go wrong
    • Fixing underlying problems
    • Managing changes to systems
    • Keeping track of what you have
    • Rolling out new releases

    These processes were split into two main groups: service support and service delivery. This made ITIL much easier for organizations to understand and put into practice.

    ITIL Version 3: Thinking About the Full Journey

    In 2007, ITIL version 3 introduced a new way of looking at services. Instead of just focusing on individual tasks, it showed how services move through different stages of life:

    1. Strategy – Planning what services you need
    2. Design – Figuring out how to build them
    3. Transition – Moving them into production
    4. Operation – Running them day-to-day
    5. Continual Improvement – Making them better over time

    This version described 26 different processes across these five stages. It helped organizations see the bigger picture and connect their IT work to their business goals.

    ITIL 4: Designed for Today’s Digital World

    ITIL 4 launched in 2019 with major updates to fit modern technology. The world had changed – companies were now using cloud computing, Agile methods, and DevOps practices. ITIL needed to catch up.

    The biggest change is that ITIL 4 focuses on creating value together with customers, not just delivering services to them. It recognizes that different teams work in different ways, and that’s okay. Whether you’re using Agile, DevOps, Lean, or traditional methods, ITIL 4 can work alongside them.

    Moving from Lifecycle to Value Chain

    ITIL version 3 showed services moving through stages in order, like a production line. ITIL 4 takes a more flexible approach with something called the Service Value System.

    At the center is the service value chain, which has six main activities:

    • Plan
    • Improve
    • Engage
    • Design and transition
    • Obtain/build
    • Deliver and support

    The key difference is that these activities don’t have to happen in a fixed order. Teams can mix and match them based on what they need, making it easier to work quickly and adapt to changes.

    From Processes to Practices

    ITIL version 3 had 26 processes that told you exactly what to do. ITIL 4 changes this to 34 “practices” – a broader concept that includes not just workflows, but also the people, tools, and information you need.

    These practices fall into three categories:

    • General management (like strategy and risk management)
    • Service management (like incident and problem handling)
    • Technical management (like deployment and infrastructure)

    By calling them practices instead of processes, ITIL 4 gives organizations more freedom to adapt things to their own situation while still achieving the same goals.

    Why These Changes Matter

    The shift from ITIL 3 to ITIL 4 reflects how much technology has changed. Companies don’t just run simple applications anymore – they manage complex systems with cloud services, APIs, and third-party platforms.

    ITIL 4 recognizes this reality. Instead of giving rigid instructions, it provides a flexible framework that helps organizations deliver great experiences to their customers. It works with modern methods like Agile and DevOps rather than against them.

    For anyone working in IT, ITIL 4 is about enabling good outcomes and happy customers, not just following procedures. It gives you the tools to build services that can change and grow as your business needs evolve.

    Now, most recently we have ITIL5 in market, which is majorly focused on AI Governance. What do you things are the changes in ITIL5 as compared to ITIL4.

  • Hard Truth About ITIL

    Most companies don’t fail at ITIL.
    They fail at discipline.
    ITIL is simple:
    • Incidents → Restore service fast
    • Problems → Stop repeat failures
    • Changes → Reduce risk
    • SLAs → Protect customer trust
    But here’s what actually happens:
    ❌ Incidents closed without root cause
    ❌ Emergency changes every week
    ❌ SLAs tracked only during audits
    ❌ Post-incident reviews skipped
    ITIL doesn’t fail.
    Leadership without accountability fails.
    If your Problem Management isn’t reducing repeat incidents,
    you don’t have ITIL — you have ticket management.
    As a Service Delivery professional, I measure success in:
    ✔ Reduced MTTR
    ✔ Fewer repeat incidents
    ✔ Fewer emergency changes
    ✔ Happier business stakeholders
    Frameworks don’t deliver value.
    Execution does.
