ITIL Change Evaluation Process

Change Evaluation is one of the main processes under the Service Transition Module of the ITIL best practice framework. We already learned about the Change Management process. We may think of this process as an extension of Change Management.

This ITIL Change Evaluation Process comes into the picture, whenever the organization decided to make major changes to their existing infrastructure or services. This process is undertaken separately for managing risks associated with major changes to reduce the chances of failures.

As described in ITIL V3, Change Evaluation Process is initiated from & controlled by change management and taken care of by Change Manager.

This process is tightly bound with some other processes, such as Design Coordination, Transition Planning & Support, and some part of Incident Management.The purpose of change evaluation is to provide a uniform and structured means of determining the performance of a change relating to the likely impact on the business, on any existing or proposed services, the current and future IT infrastructure.

    ITIL Change Evaluation Sub-Process:

    As defined by ITIL v3, there are four sub-processes of this process. Below are the objectives and descriptions of those sub-processes, followed by a diagram to explain the ITIL Change Evaluation Process flow:

    • Change Evaluation prior to Planning: To assess & evaluate a proposed major Change before authorizing the Change planning phase.
    • Change Evaluation prior to Build: To assess & evaluate a proposed major Change before authorizing the Change build phase.
    • Change Evaluation prior to Deployment: To assess & evaluate a proposed major Change before authorizing the Change deployment phase.
    • Change Evaluation after Deployment: To assess & evaluate a major Change after it has been implemented, to verify if the Change has met its objectives and to record any lessons learned from this change.

    Important Terms used in the ITIL:

    There are various following terms used in the ITIL which are required to learn:

    ITSM (IT Service Management): It is a term in the ITIL framework, which provides the services of IT in a focused and client-friendly manner. The main component of ITSM is a framework which design the services according to the SLA. And, that framework is known as SLM (Service Level Management).

    CI (Configuration Item): It is a component having a direct impact on the delivering IT services. The information for each Configuration Item is automatically stored in the configuration record within the CMS (Configuration Management system).

    This term includes the services of IT, software, hardware, building, and the formal documentation such as SLAs (Service Level Agreement).

    CMDB (Configuration Management Database): This component is used for storing the configuration records, which contains the attributes and the relationships of CI. It is a term, which also tracks the inter-relationship between all the Configuration Items.

    CMS (Configuration Management System): A CMS is a collection of tools and databases, which manages the configuration data of IT services providers. It is a component, which also contains the information about the problems, changes, known errors, and incidents. It may also contain data about suppliers, business units, customers, employees and the end-users.

    Incident: It is a component in ITIL, which is the reduction in the quality of the IT service or an unplanned interruption to the organization’s IT services. It is also defined as the failure of a configuration item.

    Service Level Agreement (SLA): In the ITIL framework, there is an SLA agreement in an organization between the customer and the IT service provider. This agreement describes the services of IT and defines the responsibilities of the customer and the provider. Service Level Agreement also describes the document level service targets.

    Operational Level Agreement (OLA): In ITIL, there is also an Operational Level Agreement in an organization of IT between the service provider and other parts of that organization. This term defines the services or goods which are to be provided. And, it also defines the responsibilities of both the parties.

    Service Lifecycle in ITIL:

    The ITIL framework is completely based on the lifecycle of a service. The lifecycle of IT Service Management is also called a ‘Plan-Do-Check-Act (PDCA)’ or ‘Deming Cycle’. It helps the service providers to achieve a better understanding of its structure. It also defines the process of how the services are started and maintained.

    The lifecycle of a service in the framework of ITIL is broadly classified into the following five stages:

    • Service Strategy
    • Service Design
    • Service Transition
    • Service Operations
    • Continual Service Improvement

    Each stage in this life cycle contains the various processes of ITIL and all the stages are interconnected. Now, we will learn about each stage of the service lifecycle one by one.
