A Definition and Overview of ITIL and the ITIL Exam

By Anthony Biggs


ITIL is a framework that gives guidance on identifying, planning, delivering and supporting IT Services to the business. Making use of the ITIL framework ensures that IT services are aligned to business expectations, which allows business to respond efficiently and effectively towards the ever transforming surroundings. ITIL has grown to become possibly the most generally followed IT Service Management Frameworks, which includes organizations like NASA, HSBC Bank and Disney who've successfully integrated ITIL. Contemporary IT Departments are faced with the battle of implementing an increasingly customer focused approach to IT Service Management and performing superb IT Services at a lower cost is developing into the standard. Also, it is fundamental that IT Services are aligned to business needs, actively assist them and underpin the business processes. In addition it is increasingly becoming obvious that IT is the agent of change in a number of businesses and helps business improvement.

IT has become a valuable member of the business and more often than not could be the collapse of the business if it is not managed professionally. Business relies heavily on the reliability and availability of IT service and substantial disruptions or outages will have disastrous consequences on, not really just the bottom line, but reputational damage as well (Blackberry being a prime example).

ITIL utilizes a Service Lifecycle technique in their framework which comprises of the following Lifecycle components:

Service Strategy

Service Design

Service Transition

Service Operations

Continual Service Improvement

This lifecycle is a constant evolution that is focused on continual enhancement of all of the other lifecycles,resulting in a continual improvement process. These several elements are addressed in greater detail under the ITIL Expert chapter. It is very important to understand that ITIL is technology provider agnostic and is particularly focused on the principles of IT Service Management instead of just the management of the particular technology itself (this is for architecture). ITIL has several supporting publications with COBIT and Prince2 experiencing the most synergies. ITIL is comprised of quite a few processes with Change Management, Configuration Management, Problem Management and Incident Management being by far the most applied processes.

The ITIL Certifications are broken down into 2 primary parts, ITIL Foundation and ITIL Expert together with a practical (or experience related) ITIL Master certification which has been released on the 1st May 2012. The ITIL Exams, which are usually written after each module, may be done electronically or paper based at licensed testing centres. To pass an ITIL Exam is considered the most satisfying exams to successfully pass and displays expertise in the IT Service Management (ITSM) field. The ITIL Expert certification follows a capability stream and a Lifecycle stream and these may be mixed and matched as long as a total of 22 credits are obtained to attain the ITIL Expert certification. The ITIL course may be taken online or at an licensed academic facility.

To complete the Expert courses physical presence is necessary but this could be supplemented by online courses. Most course materials comes in a ITIL pdf file format. ITIL Jobs are reasonably easy to find and any organization which has accepted ITIL really is a company worth working for.
