IT SERVICE LIFECYCLE

The lifecycle is comprised of 5 phases:

  1. Service Strategy
  2. Service Design
  3. Service Transition
  4. Service Operation
  5. Continual Service Improvement

The ITIL Service Lifecycle phases are interconnected components that rely on service standards, processes, roles, and performance measures. All phases run continuously and depend on the other phases to maintain a high-functioning IT service.

1. SERVICE STRATEGY

The first phase of ITIL’s method to IT service management is Service Strategy. This phase contains four main processes and lays out the terms in which a service provider can assist an organization in meeting their goals and objectives.

1. Service Portfolio Management (SPM): manages the customers interests across the lifecycle through four steps: Define, analyze, approve, and charter.

2. Financial management: part of the IT service that keeps track of the money flowing in and out of the service making sure funds are available for the development of new services. There are three sub-divisions in financial management: budgeting, accounting, charging.

3. Business Relationship Management: analyzes the demands of current and future customers and assures that the correct services are created and defined to meet the demands.

4.Demand management: facilitates the service provider in the realization and actualization of the needs of the customer demands.

 

2. SERVICE DESIGN

This second phase uses the ideas defined in the service strategy stage to create methods to follow in order to achieve business goals. Here are service design terms and concepts to know.

Design coordination: organizes all service design operations, procedures, and assets.

Service Catalog Management: controls the production and renewal of the service catalog; ensuring it consists of all necessary information on the services being delivered and to be delivered in the future

Service Level Management: mediates the contracts for Service Level Agreements with customers to ensure all needs will be met. Service level management encompasses multiple types of agreements on several different levels.

Availability Management: method used to evaluate whether IT services meet present and projected availability needs of the business being serviced in an economical and time-effective manner. This management takes place at two interdependent levels Service Availability and Component Availability in two ways.

IT Service Continuity Management (ITCM): assesses uncertainties that have the potential to jeopardize the service, used to assist with BCM.

Information Security Management: safeguards the privacy of several different varieties of an IT services information.

Security Policy: a defined set of procedures and formal documents adhered to and agreed upon at all levels that lay out how an organization deals with security incidents.

Information Security Management System (ISMS) consists of 5 parts, each with their own objective in order to address all aspects of security threats.

  1. Plan
  2. Implement
  3. Control
  4. Evaluate
  5. Maintain

Capacity Management: the organization of making certain that the IT service has the ability and infrastructure to deliver promise services to a customer.

  • Business Capacity Management: evaluating business demands in the future will be available when the need for them arises.
  • Service Capacity Management: overseeing the daily operations of IT services in the field.
  • Component Capacity Management: IT infrastructure operations evaluating if everything is running smoothly or if changes are needed.

 

3. SERVICE TRANSITION

Implement new methods created in the earlier lifecycle, through seven main processes of Service Transition.

1. Transition Planning and Support: large-scale release strategy design detailing how assets are used and how it will occur in the agreed upon capacity, time frame, and expenditure.

2. Change Management: conduct valuable changes within all phases of the lifecycle to facilitate limited interruptions to the IT services.

  • Requests for changes (RFCs): formal outline proposing changes. There are three types of changes: Standard change, Normal change, and Emergency change.
    • Standard Change Model: processes occurring before changes are complete; Role, Initiator, Change management.
  • Remediation Planning: the plan created to restore the original IT services if the changes implemented do not work.
  • Change Advisory Board (CAB): Change Management support to analyze and prioritize possible changes.
  • Emergency Change Advisory Board (ECAB): a subdivision of the CAB that determines Emergency Changes with a high-significance to the IT service.

3. Service Asset and Configuration Management (SACM): gather data about the configuration items necessary for providing an IT service.

4. Release and Deployment Management: design, organize, and conduct the timing of releases to a variety of settings.

5. Service Validation and Testing: evaluate and establish releases are meeting customer demands; certify that IT operations are able to strengthen and sustain the service.

6. Change Evaluation: evaluate large-scale changes prior to moving on to the next lifecycle phase.

  • Evaluation report: the formal report that summarizes the Risk Profile, Deviations Report, and contains a qualification statement, validation statement, and a recommendation (if necessary).

7. Knowledge Management: assemble, evaluate, preserve, and distribute information within an organization.

  • The Data-to-Information-to-Knowledge-to-Wisdom structure (DIKW)
    • Data: facts collected and available through their organization
    • Information: context added to the data increasing understanding
    • Knowledge: information strengthened with experience and ideas
    • Wisdom: utilizes “Knowledge” to add value

 

4. SERVICE OPERATION

Service Operation is the continual daily application and management of IT services that is comprised of five main processes and four main functions.

processes-functions

5 Main Processes of Service Operation

  1. Event management: consistently monitored events and CIs; events ordered so proper action will be taken.
  2. Incident management: controls the lifecycle of every event in order to return the fundamental IT service to users.
  3. Problem management: controls the lifecycle of every problem; dominant function is to eliminate the possibility of an incident occurring and to lower the effect of incidents that are unavoidable; has two tracts.
    1. Reactive problem management: determining and resolving the cause
    2. Proactive problem management: working to prevent future occurrences
  4. Request Fulfillment: to perform requests; usually low-impact from small changes to information requests.
  5. Access Management: allows only recognized and legitimate users to gain access to a service.

4 Main Functions of Service Operation

  1. Service Desk Function: contact point for the users and coordination point for multiple IT groups/processes.
  2. Technical Management: supplies the technical knowledge for the management of the IT infrastructure.
  3. Application Management: culpable for controlling the lifecycle of applications.
  4. IT Operations Management: performs the daily tasks of the infrastructure components and applications.

 

5. CONTINUAL SERVICE IMPROVEMENT

Continual Service Improvement (CSI) supplies direction in establishing and sustaining value for the customers through improvements to the daily operations and transitions to new methods. Within this phase, you follow a seven-step improvement process, which is outlined below.

Seven-Step Improvement Process: These steps aim to improve and correct IT performance.

  1. Identify the strategy for improvement
  2. Define what you will measure
  3. Gathering the data
  4. Processing the data
  5. Analyzing the data
  6. Presenting and using the information to
  7. Implementing corrective action
