The cloud ITSM (Information Technology Service Management) market is projected to be worth around $12.2 billion by 2025 as more organizations are scouting for professionals skilled in this domain [Source: marketsandmarkerts.com]. This owes to the growing popularity of ITIL (Information Technology Infrastructure Library), the set of methods which has been boosting the efficiency of ITSM globally.
ITIL is used for both service management as well as asset management, with its process based on a 5-stage life cycle. It is believed that employees skilled in ITIL can earn 40% more salary than what they would earn in a similar role without ITIL certification. Thus, students are joining various online ITIL course to tap this benefit.
The 5-stage life cycle of ITIL includes Service Strategy, Service Design, Service Transition, Service Operation, and Service Improvement. Out of these, Service Transition plays an important role as testing is done here to ensure that the product is safe. We will be discussing this in detail and what all processes are involved in a Service Transition stage and their individual objectives.
ITIL Service Transition
Service Transition is the middle stage in ITSM life cycle and aims to coordinate the deployment of service from the designing phase to the operational phase. Some of the important uses of this stage are:
- It helps in deliberating upon what new services need to be commissioned and which old services need to be scrapped out.
- It helps in planning a proper transition of service, with time constraints and cost constraints in mind.
- It aims to minimize the risks, while also taking care of various resources.
There are 7 key sub stages in ITIL Service transition which include:
- Transition Planning and Support (TPS)
- Service Validation and Testing (SVT)
- Change Management
- Change Evaluation
- Release and Deployment Management
- Service Asset and Configuration Management
- Knowledge Management
Let’s discuss in detail about these sub stages individually and what their objectives are.

Transition Planning and Support (TPS)
TPS substage aims to smoothly transit a new or modified service into production phase, while keeping in mind various cost, time and quality factors. It also checks if the service is able to adapt to the service management processes, and aids towards improvement in that direction. Thus TPS has 2 main purposes: Planning and Improvement.
The main objectives of this substage are:
- Coordinating resources and manpower between different projects to introduce a new service, modify an existing service or scrap an old service.
- Completely monitoring the service transition phase. Also, looking out for risk factors and minimizing them.
- Ensure that service is able to adapt to the processes and service procedures.
- Constantly working on improving the quality of the service transition phase.
Service Validation and Testing (SVT)
This substage focuses more on objective evidence, i.e., showing how the service can meet customer expectations. It also assesses that the IT operations are able to run the service and assures that the release has fulfilled all specifications required.
The main objectives of this substage are:
- To perform testing on service and treat the errors, if any. Testing is performed during build, release as well as deployment.
- It also defines what exactly is the scope, purpose and capabilities of this service.

Change Management
This substage looks after all the changes which are requested and their complete lifecycle. This stage focuses on understanding the client’s changing business needs and catering to their required changes in the service.
The main objectives of this substage are:
- Checking all the changes and ensuring that only the best changes are made.
- While changes are being incorporated, there should be no disruption in the IT services due to them.
- Ensuring there are minimal disruptions so that no rework in form of changes is asked later on.
- Recording the changes being made and conducting the entire ITSM lifecycle on them, i.e., Planning, Testing, Deploying, etc.
Change Evaluation
While the Change Management substage focuses on catering to the requested changes, this substage actually evaluates whether changes need to be made or not. Whether the changes are being made to a new service or are being made in an existing service, they need to be authorized before allowed to proceed.
The main objectives of this substage are:
- Ensuring that the expectations of the client/customer are realistic.
- Assessing what are the changes in performance before making changes and after making changes and then comparing them. This is essential as resources cannot be wasted.
- Understanding why the client is asking for that change and what is the motive behind that request.
Release and Deployment Management
This substage comes into picture when the actual integration of the service with the real world is being done. It checks that the service is properly released and is available for use by the client or the customer.
The main objectives of this substage are:
- Planning, Scheduling and Controlling the release of service in the live environments.
- Ensuring that correct components of the service are released at a point of time and that no effects are made in the environment by it.
- Imparting knowledge of usage to users and other stakeholders like support staff.
Service Asset and Configuration Management
This substage of SACM deals with what all assets and configuration items are required to deploy a service. It keeps track of when they are required and at what place of deployment.
The main objectives of this substage are:
- Ensuring assets are in control of the IT team and cared throughout the lifecycle.
- Auditing assets for their versions, updates, performance and relationship among assets.
- Maintaining historical records of asset usage and their impact on delivery of IT services.
Knowledge Management
This is the final sub stage in the ITIL Service Transition stage of an ITIL lifecycle. This is a central process which aims to impart information related to all other stages within an organization.
The main objectives of this substage are:
- Gathering and analysing knowledge and then sharing it with employees within the organization.
- Improving future efficiencies by collecting knowledge today itself.
- Maintaining a central repository of Data and Information which can be used to improve future service life cycles.
An ITIL expert in India can earn an average salary of ₹10 lakh per annum. Thus, if you manage to master these concepts, you are in for a bright career ahead. So wait no more and join an online ITIL course from an authorized training partner of AXELOS.
