hi guys this is rahul from simply learn and today we're going to answer the question what is itil now itil is a set of detailed practices for it service management that focuses on aligning it services to the needs of your business so here's what we'll be covering today firstly we'll talk about why itil is so important what exactly it is the history of itil some of the advantages of itil the types of itil versions and itil certificates so now lets answer the question why is itil so important so now lets understand this better by taking into consideration a conversation here we have two friends john and jim talking to each other about itil so jim asks how we can opt for a holistic approach in the iit industry by this he means that instead of taking each of the components in the iit industry separately how can he take them as a whole or how can we see it as a whole that's when john says that earlier it was difficult but now it isn't all of that was possible with the help of itil with it businesses could collaborate with the it team so that they could deliver it services to the stakeholders jim is really interested and wants to know more about the benefits of itil so some of the benefits of itil are reduced it costs enhanced i.t services improved productivity improved return on investment improved customer satisfaction better management of business risk and service disruption and improved resource utilization now we're going to talk about what exactly itil is itil stands for information technology infrastructure library it helps all organizations to deliver id services using the most efficient methods it helps businesses to improve service levels and reduce the cost of it operations now here service levels has a different meaning it basically focuses on how an organization maintains i.t services for customers as well as it controls various activities involved in a process activities like planning designing delivering deploying and managing services now the main goal of itil is to improve efficiency and achieve predictable service delivery at the same time a major requirement is to achieve high service quality now let's talk about the history of itil itil's first version was introduced in 1989 to standardize id service management to provide for a uniform structure for service delivery itil's second version was introduced in 2001. in 2007 itis third version was introduced now this aimed to improve itil service lifecycle by introducing a new feature of feedback looping aiming to clarify the processes of itil's third version a new version of itl v3 was upgraded and released in 2011. in 2019 itil's fourth version was introduced it provided a flexible as well as integrated system for the effective management of it-enabled services now let's talk about the benefits of itil now it provides greater reliability it improves the decision making process you have a greater return on investment the quality of service is much better and it's also cost efficient now let's talk about the different types of idil so itil has five revisions iti lv1 to v4 now lets talk about the first version of itil ideal v1 talks about processes that are involved in service support such as help desk management change management and software distribution organizations and government agencies around the world began adopting the framework in the early 90s to improve their i.t services and delivery capabilities the first version consists of four major concepts availability management capacity management contingency management and cost management first let's talk about availability management we all know that in an organization there are several it services these could include infrastructure processes roles and much more now availability management ensures that these are available based on the business requirement next we have capacity management now if there are any performance based issues be it in services or resources it's handled by capacity management next we have contingency management now with this you're able to identify vulnerabilities and make sure that such incidents don't happen again and finally we have cost management with this you're able to deliver as well as manage cost effective id assets and resources next up let's have a look at the second version of it il itil v2 now this version of itl was published in the year 2001. it focused on the removal of duplicate entries helped improve the consistency of topics and inclusion of new it concepts some of the topics that were covered in itil v2 where problem management release management incident management and much more ideal v2 consists of two major concepts the first one is service support with this your delivered processes so that you can control service interruptions now let's talk about service delivery now this provides a set of principles policies as well as constraints which can be utilized for designing building and deploying services that are delivered by service providers now one thing you should keep in mind is that the second version of itl did not have an organized service life cycle unlike the version 3 that we're going to talk about very soon like i said now let's talk about version 3 of it il now this version of itil was published in 2007. it adopted more of a life cycle approach to service management with a greater emphasis on it business integration now this is another upgrade and consists of 26 processes and functions now this version consists of five major sections let's have a look at each of these sections firstly we have service strategy service design service transition service operations and continual service improvement first off let's have a look at service strategy now this is the process where you understand what the client's requirements are what does the client want from your business secondly we have service design now this aims so that you can design it services in an effective as well as efficient manner in the third step we have service transition with this you can plan build test and deploy the services into the customers environments our fourth step involves service operations now this maintains this ensures that access to it services is only given to authorized users and the issue of service failure is minimized and finally we have continual service improvement now this makes sure that the it services are always aligned to the business's needs now let's have a look at the 2011 update of itil version 3. now this edition of itl is an improvement over the previous edition it aimed to resolve the mistakes as well as inconsistencies in the text and diagrams across the suite now this version underwent a lot of redesigning and use of a larger font intended to make itil a little more approachable to the reader this version majorly highlights the service strategy volume now this version as i said before doesn't have a lot of changes but has a few important updates firstly let's have a look at service strategy now in this version a new service called service strategy manager was introduced this was for people who created as well as implemented i.t strategies that aligned with the business requirements secondly we have service design now this implemented technical standards to the service design process as well as coordinated all the activities across all designs next we have service transition so this basically introduced something known as effective change management which minimized the chances of service failure now for the fourth major concept we have service operations now the latest update of service operation provides as well as maintains the processes for effective as well as efficient handling of service requests and finally we have continual service improvement now with a clear and concise seven step model you're introduced to the improvement process now these seven steps are identifying the strategy for improvement defining what exactly you will measure gathering the data processing the data analyzing this information presenting and using the information and implementing improvement and now where is the current version of itil ital v4 now the main goal of itil v4 is to help all organizations deliver it services using the most effective methods now itil can be utilized with a number of different frameworks such as agile lean and devops now itil4 consists of two major components the four dimensions model and the itil service value system now let's have a look at the four dimensions model firstly we have organizations and people so people in the organization need to understand what their roles and responsibilities are they need to have a clear understanding of how their role adds value to the organization then we have information and technology this includes information knowledge techniques and technologies that are required for service management next we have partners and suppliers so this basically sets up contracts and other agreements between the organization and their partners so here there's a focus on the organization's relationship with businesses like the ones that are involved in design deployment delivery support and the continual improvement of services and finally we have value streams and processes now a value stream is basically a series of steps that an organization follows so that they can create as well as deliver products or services to a consumer now a well-defined process can greatly improve productivity within or across organizations so it's very important that an organization address all of these four different dimensions to ensure that high service quality is maintained now let's have a look at the service value system now this is a set of activities that are performed by an organization so that they deliver a valuable output to the end users or consumers now the svs includes elements such as guiding principles governance service value chain continual improvement and practices so first let's have a look at guiding principles now these are a set of principles that help in providing a comprehensive understanding or a series of steps of how an organization should manage a service secondly we have governance now this is responsible for controlling as well as monitoring the organization it can adapt to the guiding principles or it can define its own set of principles next we have service value chain now this is a set of activities that the business performs so that they can provide a valuable product or service to its consumers now we have continual improvement now this ensures that it services are continuously aligned to the customer's expectations and finally we have management practices these are 34 management practices that are designed so that an organization is able to achieve its goals now these practices are divided into three major categories firstly we have general management practices service management practices and technical management practices now let's talk about itil certifications now it's not only necessary that you learn about itil it's very important that you get certified in it now itil has its own certifications firstly we have the foundation certification which is an entry level certification it includes all the concepts of itr service lifecycle and service management practices after which you can take the next level exam which is the practitioner certification now this is a higher level examination which aims to increase the ability of the individual who's writing the test to adopt and adapt itil to their organization then we have the intermediate certification which helps an individual understand how to manage and coordinate the itl practice areas now one thing you should note is that if you are preparing for the certification you need to have a minimum of two years of experience in it service management next up we have the expert level certification which covers the depth of itr processes and practices across all idle disciplines and now for the final level which is the master level certification now here an individual is able to explain advanced methods of itl techniques and management practices now to achieve this certification you need to have a minimum of two years of experience in the it service management and with that we've reached the
