The ITIL is designed in such a way that the planning, selection, maintenance, and delivery of IT services of any business is systematized and standardized.

Stages of ITIL Lifecycle
For IT services to run smoothly, it is necessary to follow the principles of ITIL Lifecycles. This Lifecycle is divided into 5 stages. These are interconnected so that the end goal is always the focus.

Design of the Service
In this stage, the strategies of stage 1 are converted into activity. Now the ideas are taken to the next step and planning and designing takes place. A time period is also pre-decided within which the service needs to be executed.
This process includes:
Understanding the strategy.
Creating a prospectus for the service
Ensuring that the policies and services are cost-efficient
Short-listing efficient suppliers
Look into the security system
Transition of Service
Once designed, the strategy is tested so that it is ready to be actually performed or we can say ready to be executed. This is the stage where the procedure is thoroughly checked so that there is no issue when it is finally presented to the customer.
This transition includes:
A new service to be implemented for every design.
Every design to be tested and displayed.
Any changes required for services to be managed.
Any risks to the services also are looked into.
Accomplishing the business target.
This is where the service is presented to the customer and is ready for operation. Customer satisfaction should be ensured by the service provider here and it is his duty to see how the service is performing. If there are any issues, they need to be reported.
The steps can be summarised as:
Services are delivered to sanctioned users.
The cost should be effective and quality enhanced.
The satisfaction of the user.
Continued Improvement of Service
Though the planning, designing and implementing services is done meticulously, continuous monitoring is required so that all the strategic targets of that IT service are reached. Once these are reached, new targets can be set and the process can start again.
By ensuring the proper execution of each stage of the ITIL lifecycle, the company knows that their services and their business strategies are on the same page.
Guiding Principles of ITIL
These are a few rules of ITIL which might be common to other methods too.
- Focusing on creating value directly or indirectly
- Acknowledge what is good and work on the weaker aspects
- Work on small projects, improvising while the job is being done and measuring the work done for future reference.
- Transparency amongst the team members as well as the shareholders and owners of the company as this always proves beneficial to all concerned.
- The undertaking of a project until its completion should have a holistic approach to it as this is the responsibility of the service value system (SVS)
- The employment of resources, tools, procedures should be optimum and practical as time and finances both matter.
- Human Resources should be involved only when necessary as it is easier with software.
ITIL looks at how the knowledge of the admins can be utilized for the benefit of the organization at a larger scale.
ITIL is beneficial as stated under:
- The business and its IT department are aligned better as far as the goal is concerned.
- Service is provided within the timeline and there are happy customers.
- Resources are optimally utilized resulting in cost reduction.
- There is more clarity on the cost and assets of IT.
