IT Service
A service based on the use of information technology. An IT service creates value for customers by facilitating outcomes they want to achieve without the ownership of specific costs and risks.
Impact
Shifting from "managing servers" to "managing services" is the primary maturity leap for IT organizations.
Weinto take
A service must have a defined Interface and a SLA. If you can't define the input, the output, and the guarantee, it's not a service; it's just some work you're doing. We treat every internal team as a Service Provider with a clear contract with the rest of the business.
