The ITIL Service Lifecycle

The framework of ITIL is divided into five core categories:

→ Service Strategy

→ Service Design

→ Service Transition

→ Service Operations

→ Continuous Service Improvement

The output of each of the above-mentioned processes is considered to be the input of the following process. The ITIL framework helps enterprises to integrate service and business strategies, oversee examine and enhance performance, and bring down the cost as well.

Service Strategy Process

This process involves developing service concepts and also in enabling the service selection to be provided.

Service Portfolio Management Process:

This deals with the complete set of services that comes under one management by a service provider. This includes three primary components they are

  • Service Pipeline
  • Service Catalog

Retired Services

The service portfolio management provides a systematic approach to identify, evaluate, explain and select the process.

Demand Management Process:

This process deals to comprehend and regulate the requirement of the customer.

Demand Management models are framed in terms of:

  • User Profiles, to categorize various groups of users for a required service.
  • Patterns of Business Activity helps to identify how the users of various user profiles use a service in a given time frame.

Financial Management Process:

The Financial Management Process helps users to comprehend and manage costs. This includes the following components

  • Accounting
  • Budgeting
  • Charging

Strategy Operations:

This deals to check if the user requests are full-filled if the service failures are addressed and resolved in time, and also to check if the day-to-day operational skills are done efficiently.

Service Design Process

This phase of the ITIL service lifecycle deals with the design of services.

People, Processes, Products, and Partners are the four 'P's' of Service Design' that should be ideally considered while designing a service.

Following are the processes involved under Service Design:

  • Service Catalog Management - Service Catalog has a list of services that are available to users and customers. The service catalog is made accessible to the customers. It is most often functions as an entry point for all the information services in the live environment.
  • Service Catalog Management helps to control and manage the service catalog that holds all the data about the services that are available to the customers currently.
  • Service Level Management - This is a process that deals with managing the service level agreements between the service providers and the customers corresponding to the levels of reliability and performance related to particular services.
  • Operational Level Agreements - These are performance agreements that are almost similar to SLAs.
  • Availability Management - This process focuses on the management of availability requirements that are mentioned in the Service Level Agreements. Availability is defined as the configuration or any other service to be performed when required.
  • Capacity Management - This process deals with the level of capacity that is readily available to meet the business requirements as mentioned in the Service Level Agreements.
  • Service Continuity Management - This is a process that oversees if the IT Service Provider ensures to deliver the services agreed-upon during the Service level agreement. This ensures to provide a consistent and complete Business Continuity Plan.
  • IT Security Management - This process deals with the protection of the information and the IT assets involved. This is performed by ensuring confidentiality, availability, authenticity, and integrity of the information assets.
  • Service Transition - This process deals to build and implement IT services. It also ensures to check if the changes made to services are performed in an organized and defined way.
  • Change Management - This aims to monitor and control the lifecycle of all the changes made.
  • Change Evaluation - This aims to examine the prominent changes that are made recently prior even before the changes that are allowed to proceed to the next stage of the lifecycle.
  • Project Management - The objective of this process is to plan and organize the deployment of resources to implement a release within the pre-planned cost and quality.
  • Application Development - This ensures to make the applications available to deliver the required IT services.
  • Release and Deployment Management - The main aim of the process is to organize, schedule, and oversee the movement of releases to test and live environments.
  • Service Validation and Testing - This process is to check and validate if the services of the deployed releases meet the customer demands and also ensures to check if the IT operations qualify to deliver support to the upcoming new service.
  • Service Asset and Configuration Management - The objective is to keep the information of configuration items that qualify to deliver the required or expected IT service.
  • Knowledge Management - This process assures the collection, examination, archive, and exchange of information and knowledge within the organization.

Service Operation

  • Event Management - This process monitors the services constantly and categorizes the events to decide on suitable actions.
  • Incident Management - This process aims to manage the complete lifecycle of the incidents.
  • Request Fulfilment - This process aims to instantly provide solutions to the service requests
  • Access Management - This process deals to provide authorization to the specific users to access the service and prevent unauthorized users from accessing the services. The access management process implements a certain set of policies framed by the Information Security Management.
  • Problem Management - The aim of this process is to manage and oversee the complete lifecycle of all the associated problems. It helps to deny incidents from happening or to an extent minimize the influence of incidents that cannot be prevented.
  • IT Operations Control - The process is to manage and oversee the IT services and their associated infrastructure. It ensures to execute and run daily tasks corresponding to the operations of components associated with the infrastructure, and applications
  • Facilities Management - It ensures to deal in managing and monitoring the physical environment of the IT infrastructure.
  • Application Management - This involves controlling and monitoring the applications throughout the complete lifecycle.

ITIL CSI (Continual Service Improvement) Process

This phase of the lifecycle aims to implement techniques from quality management to understand the failures and successes that have happened in the past. It also delivers processes for the IT organizations to evaluate and enhance the technology implemented, service levels, the effectiveness of the entire management of services.

  • Service Review - This is to review infrastructure services and business services consistently.
  • Process Evaluation - This helps to examine the process regularly.
  • CSI Initiatives - This is to decide on particular initiatives that would help to improve the processes and services corresponding to the reviews and evaluations.
  • Monitoring of CSI Initiatives - This is to check if the CSI initiatives are working as per the plan and to implement remedial measures if required.
