ITIL V3 introduced Service validation and Testing as a new process to test and validate the new services or changes to the existing services being introduced. The main purpose of the service validation and testing is to make sure that the IT service which has been newly implemented or modified matches its design specification and adequately meets the needs of the business. It provides confidence that a release will result in the creation of a new service or change the existing service, which in turn delivers the outcomes as expected. It also delivers optimum value for the customers within the projected costs and the capacity and constraints available at that time. It provides a confirmation that the requirements of the customer and stakeholder are correctly identified and defined. The process also helps to identify, analyze and solve the issues, problems, and risks which occur throughout the service transition process. Service validation and testing can be applied throughout the service lifecycle in order to provide assurance about the quality of any aspect of a service.

Let us look at the objectives of this lesson. Describe the complete overview of the purpose, objectives, scope, and importance of SVT as a process, the various test models, test and validation conditions.

Quality assure a release, its constituent service components, the resultant service and service capability delivered by a release. Provide confidence that a release will create a new or changed service or service offerings that deliver the expected outcomes and value for the customers within the projected costs, capacity and constraints. Confirm that the customer and stakeholder requirements for the new or changed service are correctly defined and remedy any errors or variances early in the service lifecycle as this is considerably cheaper than fixing errors in production.
The primary objective of ITIL Service Validation and Testing Process is to ensure that developed releases and the resulting services meet customer expectations in terms of its quality and the value it provides to them. This process also ensures that the IT operations team would be able to fully support the new service. The Validation and Testing process complements the service provider's responsibility for delivering, operating, and maintaining service assets and providing specified levels of warranty on them. Testing is equally applicable for the in-house and as well as externally developed software, hardware, services or knowledge-based services. The scope includes the testing of new or changed services or components and also examining the behavior of these in the targeted business environment. The ITIL Service Validation and Testing Process directly supports the Release and Deployment Management to ensure that appropriate levels of testing are performed during the build, release, and deployment activities. Further, this process works with Incident Management in the initial period of deployment.
