ITIL describes best practices for the effective and efficient provision of IT services. ITIL was started in the 1980's when the IT services provided to the British government did not meet expectations, and a method had to be found to achieve better quality at lower costs.
Today, ITIL is the most widely accepted approach to providing IT services. In our history of ITIL you can read more about how the framework has evolved over the years into the edition of ITIL 2011 and the most recent version of ITIL 4 (2019).
There is also a growing trend towards "enterprise service management (ESM)" - shorthand for applying the ITIL approach beyond its traditional use in IT.
Organizations that wish to demonstrate the quality of their IT service management processes can get certified against ISO 20000.
The ideas behind ITIL
If you are new to ITIL and service management, we recommend that you first understand the key principles behind ITIL.
ITIL is not the only service management approach around, and if you are looking for a good first introduction to ITSM and enterprise service management best practice you can watch the video series about the "simple principles of good service management" on the YaSM site. In the first video, we discuss how customer focus is the key to success.
At the top level, ITIL is organized around the "ITIL Service Lifecycle" (see Fig. 1), and each of the five service lifecycle stages consists of several processes. The idea is that service providers check, on a regular basis, if their services are delivered according to expectations, and take corrective action if necessary.
The ITIL Service Lifecycle and the ITIL processes are modelled upon a well-established management method for continual improvement, known for example as the "Plan-Do-Check-Act" or " PDCA cycle" that was made popular by Edwards Deming (see article in Wikipedia: PDCA).
In this ITIL Wiki you will find descriptions of the ITIL stages and processes, including detailed information about the ITIL processes and sub-processes, complete with their inputs and outputs, corresponding ITIL roles, as well as process metrics (KPIs):
The ITIL Glossary in this Wiki provides definitions for the most popular and essential terms and acronyms used in ITIL® and IT Service Management (ITSM).
Many ITIL terms relate to documents or records produced by the ITIL processes, and ITIL describes in quite a bit of detail what information should be contained in these documents and records. For example, in the Incident Management process we create Incident Records, and ITIL contains specific recommendations for the information that should be contained in such records.
So in the ITIL Wiki we provide a collection of the most popular templates and checklists, explaining the most important ITIL process outputs in detail.
ITIL defines responsibilities through roles, where a role is "a set of responsibilities, activities and authorities granted to a person or team".
Here in the ITIL Wiki you can find a complete list of ITIL roles with their specifications.
There are also detailed RACI or responsibility matrices for each ITIL process, as in this example, the RACI matrix for Incident Management.
How to adopt ITIL in practice: ITIL implementation projects are characterized by a typical course of action, and the page about implementing ITIL provides advice for your ITIL initiative.
This advice includes an ITIL Implementation Guide in 10 Steps with detailed instructions on how to set up and carry out ITIL implementation projects, which can serve as a guideline for a wide range of ITIL initiatives.
For a quick overview, please check out the infographic about ITIL implementations.

IT Process Maps
The People behind the ITIL Wiki
IT Process Maps, founded in 2006 by Stefan Kempter and Dr. Andrea Kempter, specializes in the provision of reference process models ("process templates") for service providers based on time-tested best-practice recommendations.
Our well-founded know-how in the fields of IT management as well as process and project management stems from many years of experience as IT line managers and business consultants, working for leading businesses worldwide from a broad spectrum of industries.
Our business is the provision of ready-to-use process templates and know-how to support you in your service management initiatives based on ITIL®, YaSM® or ISO/IEC 20000.
ITIL Process Templates
Our ITIL reference model (the "ITIL® Process Map") on which this ITIL Wiki is based has successfully passed a thorough review by APMG, resulting in the awarding of the ITIL® Licensed Product logo.
The ITIL Process Map is a professional, complete and well-structured ITIL process model. We designed it
- To give our customers an easy access into ITIL.
- To enable them to take their ITIL initiative into their own hands, reducing the need for external consulting.
The ITIL® Process Map V3 2011 Edition covers the full ITIL 2011 service lifecycle. It is available as a complete process model for Microsoft Visio (ready for MS Visio 2016), for ARIS™ and for other widely used process management platforms.
The YaSM process model for service management
Our approach to presenting the ITIL concepts in the form of process diagrams and document templates has been well received and is used by hundreds of organizations world-wide.
These organizations are generally in favor of service management best practice such as ITIL, but many also asked, "couldn't this be a bit less complex?".
It was this apparent need for something simpler which sparked the creation of YaSM, which stands for 'Yet another Service Management Model'.
- The free YaSM Service Management Wiki offers a complete introduction to YaSM, our streamlined process model for service management and ISO 20000.
- The wiki provides examples of how YaSM can be applied to improve the delivery of services.
From the Service Management Wiki:
