ITIL (IT Infrastructure Library) is a methodology that describes the life cycle of IT products. It appeared in the 1980s at the request of the British government, which wanted to develop a standard for assessing the quality of IT services. In 2013, the rights to the methodology were given to Axelos, which the UK government created with Capita.
ITIL describes several stages of the life cycle of an application, product or service: strategy, design, transformation, operation, continuous improvement. The goal of the methodology is to establish links between IT departments and customers and improve the quality of services provided. Additionally, it reduces development costs by optimizing the resources used. Several Japanese industrial enterprises have been able to use ITIL to cut manufacturing costs by 30% in three years, according to Gartner.
During the existence of the methodology, three versions of the ITIL standard have been released. The last one was published in 2011. Over the past eight years, the IT industry has accumulated a critical mass of new practices. For this reason, Axelos announced plans to update the library in November 2017.
The test provides an opportunity to pre-assess the degree of readiness for the certification exam, get acquainted with the specifics of the wording of exam questions and identify areas that require additional training.
Each test question can have up to four answer options (A, B, C, D), only one of which is correct. For the correct answer 1 point is awarded. To successfully pass the test (like the official exam), you must score 26 or more points.
