The transition lifecycle stage takes overall care of transitioning an organization from one state to another while delivering capabilities for service operation and continual service improvement. The main aim of the transition stage is to plan and manage changes efficiently and effectively while controlling risks and delivering knowledge for decision support.

The transition guidance covers the practices in change management, service asset and configuration management, release and deployment management, change evaluation, and knowledge management and places them in the practical context of service management.

Objectives of ITIL® Service Transition

The key objectives are enlisted as follows:

• Regularly monitor the current services for efficient performance and results.
• Manage the service assets and related components for quality during the service transition.
• Maintain and regulate the deployment of the available resources from scratch to release into production.
• Check whether the quality meets the requirements of stakeholders and customers.
• Ensure necessary information regarding building and installation from production during test environments is provided. Also, the mechanism should ease rebuilding the requirement of resuming the service.
• Establish service management, operation and support within the design constraints to avoid external assistance.

Scope of ITIL® Service Transition

The extent of services offered by ITIL® Service Transition considers retirement and service transfer between service providers. It encompasses the development and improvement of capabilities for transitioning new and modified services into a supported environment, including planning, building, analysis, and implementation. 

Value to Business of ITIL® Service Transition

There are numerous benefits of  ITIL® Service Transition, such as:

• Better chances of successful change
• Reduces effort in the management of test and pilot environments
• Upgrades the trust of stakeholders by enhancing productivity
• Supply the business with precise cost and resource requirements, along with delivery time and potential risk management
• Prediction of issues helps in time management.
• Efficient service transition is accompanied by conviction in modified services according to required specifications.
• Secures easy and cost-effective new and modified services
• Better regulation of various service assets and configuration
• Flexibility to new requirements or services

Key Principles of ITIL® Service Transition

It is crucial to define the formal policies for service transition before implementation clearly. Some of the formal principles/policies are as follows:

• Management and prediction of course corrections
• Efficient utilization and repurposing of current services
• Execution of required changes and maintaining best services  during service transition
• Set up effective controls
• Assist in knowledge transfer and decision-making
• Understand the stakeholder's requirements and make the correct delivery
• Ensure alignment of service and business plans
• Take responsibility for new and modified services.
• Efficient management of service handles resources.

ITIL® Service Transition Process

The ITIL® transition process incorporates the following important activities:

• Define the Strategy

Describe the transition strategy with a transparent indication of roles, policies, responsibilities, frameworks, criteria for success and standards.

• Evaluate the Service Transition

Begin the preparation, evaluate the service transition and make changes based on recommended inputs. Analyze the readiness for transition and configuration criteria to ensure the accuracy and feasibility of changes. 

• Discuss the Transition

The service transition should be coordinated before the release. It includes planning, reviewing and further incorporating the transition before client distribution.

• Provide Support for the Transition

Ensure complete assistance in the management, evaluation and advancement of the transitioning process and its application.

Challenges in ITIL® Service Transition

The most common hurdles faced are as follows:

• Development of connections with numerous stakeholders associated with the transition.
• Issues with utilizing new and modified service transitions in case of providing improved transitions or delayed results.

Risks in ITIL® Service Transition

Several risks associated with ITIL® Service Transition are as follows:

• The communication gap between the project and program teams results in unforeseen needs for service transition.
• Conflicting requirements or lack of information hinders the building and, eventually, deployment.
• Delay in any transition might affect other processes and transitions.

Service Asset and Configuration Management (SACM) is IT Services 

Release and Deployment Management in IT Service Transition

Release and Deployment Management is a set of various strategies, key points, and techniques including building and testing the release, planning a release, planning the deployment, planning pilots, deploying the release, testing the deployment, communicating with change management and inform the change management that release has been deployed.

The overall process of release and deployment is interlinked with Service Validation and Testing, Change Management and Service Evaluation. The final release needs a green signal from the Change Advisory Board (CAB) to go into production; this approval approves that the product is monitored during all stages of release and deployment, so it's all set for mass production. Release and Deployment Management also makes it sure that customers have the skills and knowledge to use the service to its full potential and that the support staff and operations are well informed about the service levels and the warranties of the product. The Release and Deployment Management department is also considered the lifeblood of the Service Transition process.

FAQs

1. What is the service transition of ITIL®?

The service transition of the Information Technology Infrastructure Library (ITIL®) aims to assist in the planning and managing of the state of service change during its period.

2. What are the five stages of ITIL®?

The five stages of ITIL® are Service Strategy, Service Design, Service Transition, Service Operations and Continual Service Improvement.

3. What is the meaning of service transition?

Service transition refers to changing the state of a service based on service risk and curating service knowledge. Service risk is significant for businesses in delivering quality results, and curating service knowledge involves adopting informed decisions with stakeholders.

3. What is an IT transition life cycle?

The IT transition life cycle is the transition of IT services. The important task here is ensuring the smooth functioning of services and the successful delivery of results while services are transitioned to new or modified forms.

4. What are the different types of transitions?

The three types of transition are standard, normal and emergency. A standard change is done on service requests or operational usage. Normal changes can be automatic or on request by users. Emergency change is done on an urgent basis and skips the standard process.
