Key differences between ITIL V3 & V4. A quick glimpse for everyone…

Key Differences Between ITIL V3 & ITIL 4

The transition from ITIL V3 to ITIL 4 reflects a significant shift in how IT service management (ITSM) is approached, particularly in light of the rapidly changing business and technology landscapes. ITIL 4 is designed to align with modern ways of working, including Agile, Lean, and DevOps, and to emphasize digital transformation, automation, and value co-creation. Below, we’ll explore the key differences between ITIL V3 and ITIL 4 in more detail.

1. Practices vs. Processes

In ITIL V3, the concept of processes formed the backbone of service management. V3 identified 26 distinct processes that spanned the entire service lifecycle, each focusing on specific service management tasks (e.g., Incident Management, Change Management). These processes were prescriptive and often siloed, with each focusing on achieving individual goals.

  • ITIL V3: Focused on 26 processes spread across different phases (Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement).

In ITIL 4, the concept of practices replaces processes. Practices are broader and more flexible, combining governance, management, and continual improvement. Practices are not confined to a strict service lifecycle but can be applied dynamically based on specific needs. ITIL 4 includes 34 practices, emphasizing adaptability and collaboration.

  • ITIL 4: Focuses on 34 practices, enabling flexibility and adaptability in service management, with more integration across the organization.

This shift from processes to practices enables organizations to move away from rigid, process-driven workflows to a more collaborative, cross-functional way of working. The new approach also aligns better with Agile and DevOps methodologies.

2. Service Value System (SVS) vs. Service Lifecycle

In ITIL V3, the service management framework was structured around the Service Lifecycle. The five key stages of the lifecycle—Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement—offered a sequential, phase-driven approach to managing IT services. While effective, this approach often felt restrictive and overly linear in dynamic environments.

  • ITIL V3: Emphasizes a sequential lifecycle of service delivery, making it difficult to adapt quickly in an agile environment.

ITIL 4, on the other hand, introduces the Service Value System (SVS), which is a holistic framework designed to create, deliver, and continually improve services. The SVS incorporates components like the Service Value Chain, guiding principles, and governance. The Service Value Chain is the heart of the SVS and is a flexible, non-linear approach that enables organizations to tailor their activities to specific requirements, fostering agility and responsiveness.

  • ITIL 4: Introduces a more holistic Service Value System (SVS), offering a flexible framework for co-creating value. It emphasizes continual improvement and cross-functional collaboration, rather than following a rigid lifecycle.

3. Enabling Value Co-Creation vs. Delivering Value

In ITIL V3, the primary focus was on delivering value to customers. Services were often developed, managed, and delivered by the service provider with little emphasis on customer collaboration during the service design and delivery phases. This provider-centric model was suitable for stable environments but less effective in dynamic, customer-driven contexts.

  • ITIL V3: Focused on delivering value to customers through defined service levels, largely determined by the service provider.

ITIL 4 introduces the concept of value co-creation, where service providers and customers work together to create value. This shift acknowledges the collaborative nature of modern service delivery, where customers are active participants in shaping the services they receive. The focus on co-creation aligns ITIL 4 more closely with Agile and DevOps principles, which emphasize frequent customer feedback and iterative improvement.

  • ITIL 4: Focuses on co-creation of value, encouraging collaboration between the service provider and the customer to achieve the desired outcomes.

4. 34 Practices vs. 26 Processes (with Four Functions)

ITIL V3 consisted of 26 defined processes, each mapped to different stages of the Service Lifecycle. Additionally, V3 introduced four key functions—Service Desk, Technical Management, IT Operations Management, and Application Management. Each function had a specific, isolated role within the overall service management framework.

  • ITIL V3: Comprised of 26 processes and four functions, with each process and function operating independently to achieve predefined goals.

ITIL 4 has simplified this by introducing 34 practices that combine both processes and functions into a single structure. These practices cover a broader scope than V3’s processes and functions, providing a more comprehensive approach to service management that integrates governance, improvement, and service delivery activities. ITIL 4 practices are also designed to be more adaptable to different contexts and are not bound by lifecycle phases, allowing for a more fluid approach to managing IT services.

  • ITIL 4: Combines processes and functions into 34 practices, allowing for a more holistic and flexible approach to service management.

5. Four Dimensions of Service Management vs. Four Ps of Service Design

In ITIL V3, the Four Ps—People, Processes, Products, and Partners—were key considerations in Service Design. These Four Ps were essential for designing effective services but were mainly focused on ensuring the proper functioning of IT systems and processes.

  • ITIL V3: Used the Four Ps (People, Processes, Products, Partners) primarily in service design to ensure smooth service delivery.

ITIL 4 introduces the Four Dimensions of Service Management, which provide a more holistic view of service delivery. These dimensions are: Organizations & People, Information & Technology, Partners & Suppliers, and Value Streams & Processes. This broader scope incorporates elements beyond traditional IT, addressing the organizational and technological shifts that have become critical to modern service management.

  • ITIL 4: Expands the perspective with Four Dimensions of Service Management, focusing on a more integrated and strategic approach to service design and delivery.

6. Integration with Agile, Lean, and DevOps vs. Software Development Out of Scope

In ITIL V3, software development practices such as Agile, Lean, and DevOps were considered outside the scope of ITSM. ITIL V3’s processes were often seen as too slow and cumbersome to fit into fast-paced, iterative development environments. This led to a disconnect between IT operations and development teams.

  • ITIL V3: Did not align closely with modern software development practices, leading to challenges in bridging the gap between ITSM and DevOps.

ITIL 4 bridges this gap by embracing and integrating modern development methodologies like Agile, Lean, and DevOps. This alignment allows ITIL 4 to remain relevant in organizations where development and IT operations need to collaborate closely, helping to break down silos and foster continuous integration, continuous delivery (CI/CD), and fast iteration.

  • ITIL 4: Fully integrates Agile, Lean, and DevOps into its practices, allowing for a more cohesive and responsive approach to IT service management and development.

7. Focus on Digitalization and Automation vs. Focus on Service Delivery

In ITIL V3, the primary focus was on service delivery, ensuring that IT services were available, reliable, and efficient. While effective, this focus was somewhat narrow, as it did not account for the growing role of digital transformation in business success. V3 had limited tools to address the demands for automation, artificial intelligence (AI), and other emerging technologies.

  • ITIL V3: Focused primarily on traditional service delivery, with less emphasis on emerging digital trends.

ITIL 4 places a strong emphasis on digitalization and automation, recognizing the need for ITSM to support modern digital ecosystems. ITIL 4 encourages organizations to embrace new technologies, automation tools, and digital transformation strategies to remain competitive in the digital age. This focus on digitalization is crucial in industries where speed, flexibility, and innovation are key.

  • ITIL 4: Focuses on digitalization and automation, promoting the use of modern tools and technologies to drive business value and innovation.

In summary, ITIL 4 represents a major shift towards a more modern, flexible, and integrated approach to IT service management. Its emphasis on value co-creation, digitalization, and agility makes it a better fit for today’s fast-evolving IT environments, whereas ITIL V3 was more structured and process-driven, suited for stable, predictable environments.
