Episode 15: ITIL service transition

Understanding ITIL service transition in technology procurement

Service transition is the third stage of the ITIL framework and acts as the bridge between service design and live operation. This stage focuses on managing change, preparing a service to go live, and ensuring it can evolve safely once it is running. When organisations understand how service transition works, they can avoid disruption, reduce risk, and keep services stable as the environment changes.

Let's explore the four key areas within service transition that help organisations manage change effectively.

The role of change management

Change management is all about formalising the way changes are made to a service. Whether it is adding new components, updating existing ones, or introducing new servers, change management ensures the impact is understood before anything happens.

Organisations need clarity on why the change is taking place, when it will happen, and how it will affect the rest of the environment.

From a procurement perspective, change management is essential because every change can have commercial implications. It may affect contractual obligations, trigger relief notices, or alter responsibilities. Understanding the process and how to work with suppliers during change is a vital part of designing and managing any IT service.

How release management supports software updates

Release management focuses on how new software or updates are deployed into a service. This covers both major upgrades and smaller security patches. Clear processes for testing, implementing, and validating software changes are crucial.

Organisations need to define who is responsible for each part of the process so that changes happen smoothly and securely. Including these details in statements of work helps ensure expectations are aligned across the procurement and technical teams.

Why service asset and configuration management matters

Service asset and configuration management often gets overlooked but is crucial to long-term stability. This discipline ensures every component that makes up a service is logged, tracked, and understood.

Assets include hardware, software, intellectual property, data centre components, and anything else required to deliver the service. Clear ownership and location details support effective change management and give procurement teams visibility of IP rights, asset responsibilities, and service boundaries.

When everyone understands what assets exist and who is responsible for them, support and change management become far more effective.

The importance of knowledge management

Knowledge management ensures all documentation, processes, and service information are up to date, accessible, and accurate. Without a clear knowledge base, organisations struggle to move services between suppliers, onboard new teams, or manage outsourced operations.

In larger services, knowledge management is essential for smooth transitions, including staff transfers under TUPE arrangements. Keeping documentation current prevents disruption and makes future changes far easier to manage.

Why service transition is critical for stability

Service transition is ultimately about managing change in a controlled way that protects service stability. Clear governance, well-defined processes, and shared understanding between technical and procurement teams reduce risk and prevent issues further down the line.

By taking service transition seriously, organisations can keep services resilient and easier to evolve over time.
