What is ITIL Service Lifecycle?

Information Technology Infrastructure Library (ITIL) Service Lifecycle is a framework defined in ITIL v3 for managing a product or service throughout its lifecycle. It consists of five stages, each with its own specific processes: strategy, design, transition, operation, and continual improvement. It helps to alignITIL Project Management with business objectives and improve it continuously.

Five Stages of the ITIL Service Lifecycle

The following make up the five stages of the ITIL Service Lifecycle:

Stage 1: Service Strategy

ITIL’s Service Lifecycle's first stage provides guidance on how to build and use an IT infrastructure from scratch in a non-IT setting. This stage helps organisations to gain a competitive edge by helping them to choose the best practices.

The service strategy explains how to use IT services to accomplish an organisation’s business goals. The main purpose of the service strategy is to define the framework, techniques, and direction that a vendor needs to follow to meet the company’s business needs.

Purpose of Service Strategy:

Maintaining a consistent Service strategy is necessary for organisations that provide Customer Service. It helps ensure that your service strategy aligns with the organisation's business needs. These business objectives should focus on a long-term approach rather than short-term fixes. This is where the ITIL Service Lifecycle plays a major role.

Maintaining a consistent Service strategy is necessary for organisations that provide customer service. It helps ensure that your service strategy aligns with the organisation's business needs. These business objectives should focus on a long-term approach rather than short-term fixes. This is where the ITIL Service Lifecycle plays a major role.

The organisation's IT strategies should be created in a way that supports the business strategies and does not hinder them in any way. At the same time, these strategies should be practical and easy to implement. You need to understanding of the following factors to devise such a strategy:

a) The ability of the organisation

b) The service provided

c) Customer’s needs

d) Necessary resources

e) Operating costs

Benefits of Service Strategy:

From finding the latest trends to aligning with the trends, there are many benefits to implementing a service strategy. Some of these benefits are listed below:

Stage 2: Service Design

The second stage of the ITIL Service Lifecycle gives detailed instructions to create and produce the organisation's service and methods to handle these services. It also provides design guidelines and techniques for transforming tactical goals into services.

The organisation's service strategy should focus on the organisation's business goals. So, before designing it, you must ensure it aligns with the organisation's business goals. This stage is crucial for a business as it transforms a simple strategy into a viable plan to achieve business goals.

Purpose of Service design:

The main purpose of theITIL Service Delivery Guide and ITIL Service Design is to create well-performing services that don't require frequent upgrades throughout their tenure. Apart from this, the service design should focus on Continual Service Improvement and ensure that the services perform well throughout their lifecycle. Above all, constantly analysing the varying market trends to find better investment opportunities.

Benefits of Service design

Your services can be superior and pocket-friendly if they are designed well. A good design should also meet the business goals. Some of the benefits of ITIL Service Design are listed below:

Stage 3: Service Transition

An organisation would include some elements in its strategy to enhance its current and future products and services before developing a new service. The main objective of the Service Transition stage is to make sure that the new and improved services meet the business requirements.

In the ITIL Service Lifecycle, the ITIL Service Transition stage aims to ensure the created services are ready to be used by the customers. Apart from this. This crucial phase also explicitly outlines the pivotal role of ITIL Service Management through the Service Knowledge Management System (SKMS). It helps improve learning in an organisation throughout the lifecycle of the service. It empowers employees with the hands-on experience of their peers and enhances the decision-making process.

Purpose of Service transition:

The main purpose of Service transition is to ensure that the implemented changes in service within the ITIL 4 Service Value System highlight the integral role of service transition in delivering value to the business. It also helps deliver the service releases in the right place.

Whether it's a newly released or modified service, it helps create practical expectations on the performance of these services. It helps to reduce risks to all the new, updated and terminated services. Above all, it helps learn the required knowledge and instructions on services and their resources.

Benefits of Service transition:

There are many benefits of the Service transition, and some of the benefits are listed below:

a) The Service transition gives a clear insight into the budget, the resources needed, the timeline for creating services and the overall risks faced by the organisation

b) It helps prevent unnecessary delays

c) It helps satisfy the stakeholder's expectations

d) It helps implement more changes

e) It requires minimum effort to manage testing with the help of service transition

Stage 4: Service Operational

The operation stage in the lifecycle after the transition stage. This stage is focused on providing the services to the end users. In this stage, services are delivered with lower costs and risks. It includes actions and techniques required to offer the appropriate services to the customers and guarantee customer satisfaction.

Purpose of Service Operational:

ITIL Service operation is a stage in the ITIL Service lifecycle that makes sure that the services the organisation delivers comply with the Service Level Agreements (SLAs). This is the goal of any business that provides customer services.

This stage includes gathering data, measuring work performance, and other important metrics. Besides this, it helps to keep an eye on the daily system activities to avoid any mistakes that could happen from the client side. It does this by responding to the user queries and feedback frequently.

Process of ITIL Service Operation:

ITIL Service Operation involves five processes that divide this stage into separate processes, thus increasing the effectiveness of this stage. These five processes are explained below:

a) Event Management: This process identifies, and isolates events and responds to them. It contains a list of all the events by stored it it on a record.

b) Incident Management: At times, your organisation's service may get disrupted, leading to customer dissatisfaction. The ITIL Incident Management process helps overcome these disruptions and bring all the services into working condition.

c) ITIL Problem Management: It coordinates with Event Management and Incident Management to detect the primary cause of incidents. Doing this prevents these incidents from arising in the future, as appropriate measures are already in place. In the realm of ITIL Problem Management, these coordinated efforts highlight the crucial ITIL Problem Management roles and responsibilities of professionals involved.

d) Access Management: This is a crucial process as it could affect the security of the service. It helps provide access to people with proper authorisation and denies access to unauthorised users.

e) Request Fulfilment: Once your service is released to the end-users, they may perform several actions, like creating a new account and password and changing the password, etc. These actions are called requests, and this process helps perform and manage such requests.

Benefits of Service operation:

The Service Operation stage has many benefits, such as lower cost and increased business value. These benefits are explained below in detail:

a) The operation stage manages service disruptions efficiently by addressing their root causes and hence lowers the unnecessary expenses.

b) It reduces the time span of service disruptions and occurrence so the end-user can use the service with minimal disruptions.

c) It collects useful data that can help improve the quality of the service.

d) Improves productivity by providing faster access to the IT services. Thus strengthening the ITIL Service Lifecycle.

e) It improves the security of a firm with its access management process by giving authorisation to the right users.

f) It facilitates automating repetitive tasks so the employees can focus on the essential tasks.

Stage 5: Continual Service Improvement

Continual Service Improvement (CSI) is a stage that aims to enhance the service by following quality assurance frameworks such as the International Organisation for Standardization (ISO) 2000. This service applies quality management techniques to learn from past failures and successes. It concentrates on improving IT Services’ effectiveness and value by using customer feedback.

It helps to eliminate obstacles from the service and ensures it matches the client’s needs by using continuous evaluation. Frequent evaluation of the IT services can identify where it is deficient and areas of improvement.

Purpose of Continual Service Improvement:

Some of the purposes of this stage are listed below:

a) Examine and provide suggestions to improve all the stages of the ITIL Service Lifecycle.

b) Improve the performance of the IT services and save money at the same time.

c) Improving the quality and performance of the IT Service Management by detecting and executing certain tasks

d) Maintaining quality by implementing a quality assurance standard.

e) Cutting costs for delivering the service without negatively affecting the client's expectations.

Process of ITIL Continual Service Improvement:

There are four processes of the ITIL Continual Service Improvement stage. They are presented below:

a) Service Review: This process mainly aims to assess the services and infrastructure regularly. This assessment helps tweak the service quality where it is required. It also helps find practical and cost-effective ways to provide a service.

b) Process Evaluation: This process aims to assess IT processes constantly. It helps to determine whether the metric process targets are achieved or not. Besides that, it allows benchmark metrics, reviews and assessments to be performed, and audits to be conducted.

c) Defining CSI Initiatives: This process aims to optimise the services based on the analysis and evaluations by implementing certain initiatives. Some initiatives need customer input, while others are done internally and don't need customer suggestions.

d) Monitoring CSI Initiatives: This process determines whether the initiatives for improvement go according to the plan.

Benefits of Continual Service Improvement:

In this section, you will learn the benefits of Continual Service Improvement:

a) CSI regularly monitor and improves IT services, so the overall customer satisfaction level will be high.

b) You can make well-informed decisions with CSI since it has a huge volume of data from previous work. This data also helps in forecasting events and processes.

c) It promotes more customer coordination and helps implement their feedback on the Service. This will improve customer satisfaction.

d) CSI proactively looks for new ways to improve your service efficiency.
