A summary of changes has been published by the UK Government. In line with the 2007 edition, the 2011 edition consists of five core publications – Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. ITIL 2011 is an update to the ITIL framework that addresses significant additional guidance with the definition of formal processes which were previously implied but not identified, as well as correction of errors and inconsistencies.

While ITIL addresses in depth the various aspects of service management, it does not address enterprise architecture in such depth. Many of the shortcomings in the implementation of ITIL do not necessarily come about because of flaws in the design or implementation of the service management aspects of the business, but rather the wider architectural framework in which the business is situated. Because of its primary focus on service management, ITIL has limited utility in managing poorly designed enterprise architectures, or how to feed back into the design of the enterprise architecture.

The service portfolio contains information about the performance of investments in services the service provider manages on behalf of the business. The service portfolio comprises: the pipeline section, which contains the services that are yet to be offered; the service catalogue section, which contains the details of operational services; and the retired section, which contains details of the services that are no longer offered.
However, when it comes to the IT field, getting your ITIL certification is considered to be a very low-risk effort, and many will tell you that you’d be doing yourself a huge disservice to write it off. Certified ITIL professionals are a highly sought-after commodity, and the job market is stable enough where an ITIL v3 certification in any of the higher levels will be in demand for quite a long time.
Problem management aims to resolve the root causes of incidents and thus to minimize the adverse impact of incidents caused by errors within the IT infrastructure, and to prevent recurrence of incidents related to these errors. A "problem" in this context is the unknown underlying cause of one or more incidents, and a 'known error' is a problem that is successfully diagnosed and for which either a work-around or a permanent resolution has been identified. The CCTA (Central Computer and Telecommunications Agency) defines problems and known errors as follows:
Good IT Service Management is about knowing how to integrate these factors into your development process, and this is where ITIL comes in. It covers the entire development lifecycle, from identifying requirements from a business and IT perspective, to designing and creating the solution, to delivering and maintaining the service in a state of continual review and improvement.
Bottom-line is everything right? If on-site sponsorship opportunities aren’t available to you, it’s still well worth the investment to pursue an ITIL v3 certification on your own time. Not only will you be boosting your resume and providing more value to the business, but you’ll potentially receive more lucrative job opportunities as well. ITIL is listed as one of Techopedia’s highest paying IT certifications, and it’s not uncommon for certified ITIL program managers and IT architects to make well over six figures in their respective salaries. Now that’s a lot of moolah!
In July 2013, Axelos took ownership of ITIL. It now maintains the ITIL framework and accredits training and examination institutes. Hundreds of ITIL Accredited Training Organizations (ATOs) are available to deliver training, and ITIL certification exams may be administered at the end of a training course or by an Examination Institute (EI), many of which work directly with the ATOs.
You have to submit your application to become a Master, and if your application is accepted, you will be required to submit a proposal. If this is successful, you will be required to submit a work package. The final stage of the Master scheme consists of an interview with a panel of assessors and, if successful, you will be granted ITIL Master certification.
However, ITIL certification is different. Having an ITIL certification doesn’t make us an ‘expert’ for any specific skill set. As you might already be aware, ITIL is a set of best practices and is descriptive in nature. Hence an ITIL certification isn’t about doing your job, but merely about knowing the ITIL principles. In fact, that’s precisely the reason why AXELOS have now added the ITIL Practitioner level which makes it mandatory for IT folks to apply their theoretical knowledge in practice.
