The ITIL generally takes the lifecycle approach in order to provide best practice based on the guidelines of Information technology service and its management. However, there are 5 stages of ITIL lifecycles for services, and those are Service Strategy, Service Transition, Service Design, Service Operation, and the Improvement of Continual Service.

Service Strategy

This phase of the service strategy in the service lifecycle generally provides the necessary guidance for designing, development, and finally implementing the IT service and its management. However, this service strategy can be easily developed to give businesses with quite a distinct advantage for this current competitive marketplace. In this service strategy, the companies will be able to determine the core target market by creating a difference with the competitors and themselves. However, this is necessary to have the proper strategy in order to provide the company products as well as a proactive approach for developing the business operation.

Service Transition

In this service transition phase, the basic service lifecycle generally helps to teach the IT professionals to associate the business in order to manage the major changes in a productive manner. This service transition can also provide fundamental guidance based on the effective and efficient transition of the changes to the new operations. However, this can happen without interrupting and disrupting the processes or the services.

Service Design

In this service design phase, the service lifecycle generally provides the basic guidelines for developing and designing the IT’s important services and management techniques. However, this provides typically massive support towards managing the service strategy that has already developed in this service. The process of design and planning can be prepared through IT professionals. Still, the core business leaders generally help to address the prime concerns of the consumers through an essential and proficient manner. In this concept, this can also be stated that this can develop the core strategy of the change in the services through which this has developed a basic effective formation.

Service Operation

In the service operation phase, the service lifecycle generally provides basic guidance on the basis of the practical aspects that the company may face during conducting the day-to-day affairs. The most essential goal for the IT department is keeping the necessary things running efficiently, smoothly, cost-effectively, and reliably. However, these processes, as well as the activities in this core, developed phase generally also help to ensure the services have delivered to the consumers, and they have agreed with the minimum disruptions and interruption. This is the most productive phase of IT, and through this way, this has developed and able to achieve the most fundamental approach. The service operation can also focus in order to provide the most required ethics and value for both the service providers and the consumers.

Improvement of Continual Service

In this improvement phase of the continual service, the development and improvements are also involved. It is more evident if no change has been seen in the organizations for the IT services. However, in this continual process, the primary key is based on the basic understanding of the necessary improvement that can be made based on the development of the uninterrupted service. Therefore, ITIL training can be quite helpful for learners in order to identify the significant necessary possibilities for their respective signs of progress in the IT field. This is quite necessary to involve the learning through the ITIL service lifecycle through which the ITIL training for the IT professionals can be improved.

Thus, it is quite clear from the above discussion how the knowledge and training of ITIL and its lifecycle play a vital role in the service sector.
