ITIL Definition: ITIL for Information Technology Infrastructure Library, is a set of documents that contain good practices for information systems management.

ITIL Origin: ITIL has its origins in Great Britain, specifically the British Office of Government Commerce. ITIL has quickly got success worldwide according to its results and the accession of large private and public enterprises. The original version of ITIL did not consider the technical side of IT. From third version, its scope has been revised and several key aspects in the organization are concerned. Many departments and agencies of the Government of Quebec and the federal government of Canada make use of ITIL as a reference in IT Service Management.

Some ITIL terminologies Event : Detectable or discernable occurrence, a change of state that has considerable importance to the management of an IT service. Incident: Unforeseen deterioration or interruption to an IT service. Problem: The cause of one or more incidents. The cause may not be known at the moment of the problem registration.

5



Some ITIL terminologies Function: Organizational unit specialized in the production of certain types of work and responsible for specific results. Example: Function service center (or technical support) Role: Set of responsibilities, activities and authorities granted to a person or a group of persons. Example: A manager of a service or a process owner has role and responsibilities.

6



Some ITIL terminologies Process: Series of activities realized by using resources (personnel, equipment, materials, information) to transform inputs into outputs elements and its final expected result is a product or a service. Example: process of public tender, chocolate manufacturing process, major incidents management process, ... Procedure: Set of tasks and activities that help to realize the process. Procedures must be followed to achieve the desired outcome of the process. It’s the “how” of the “what” defined in the process.

7



Some ITIL terminologies We have three categories of activities: oValue added : Directly useful to the client. o Business value added: useful / requirement for business only. oNon value added : useless, pur waste. In continual improvment of process and service, we aim to minimise the BVA and elimate the NVA. Service: It is a way to provide value to customers. According to ITIL, service value is a function of two things: Utility : The service fit customer’s needs and expectation. Warranty: The service is fit for use. Ensures the availability, capacity and security.

8



ITIL Service Lifecycle The full life cycle of ITIL consists of five steps: 1. Service Strategy : It is the phase in which the objectives are determined and decisions are made. The hierarchy is much more involved in this phase. 2. Service design : The design phase for the development of services based on the strategic vision. The design aims to meet present and future business. Converts the strategic goals into services available within a portfolio of services.

ITIL Service Lifecycle 3. Service Transition : the phase of development and improvement of skills to implement the new or modified services. 4. Service Operations: Phase of fulfillment, of services production and support to business users and customers according to the agreements. 5. Continual Service Improvement: The phase which ensures the conservation of value for customers, by keeping services up to date and aligned with the business.

ITIL maturity model There are six levels of maturity in IT Service Management Level 0: No management exist, its utility is not known Level 1: Necessity realyzed and steps are undertaken Level 2: Ad-hoc measures exist Level 3: Processes are defined and measured Level 4: Processes are regularly measured Level 5: Processes are continuously improved (CSI)

Very few organizations have the level 5. Having the level 3 is enough encouraging.
