ISO 20000 or ITSM(IT Service Management) is the international standard published by ISO (the International Organization for Standardization), and ICE (the International Electoral Commission). To become an international standard, ISO 20000 had to be agreed upon by a majority of member countries, which means it is accepted by a majority of countries worldwide.
The standard describes a set of management processes designed to help you deliver more effective IT services (both to those within your business and to your customers). ISO 20000 gives you the methodology and the framework to help you manage your ITSM, while allowing you to prove your company follows best practice. With the requirements of the standard you will achieve best practice, helping to improve your delivery of IT services. And ISO 20000 is applicable to any company size and any industry.
