The use of the term ‘Service’ is somewhat overloaded. Everyone will have heard or used the terms Business Services, IT Services, Software Services, and now Cloud Services, and yet often there is much confusion and misunderstanding in their use.As my colleague David Sprott suggested in a CBDI Journal Report, «Everything is a Service» . In that report David suggested that the idea that «everything is a service» could be developed to clarify the taxonomy for Cloud Services and Services in the form of a Unified Service Model that would deliver convergence of business and IT perspectives.Consequently, I have penned a research note available on Everware-CBDI site , that provides a concept model that explores the basic concepts of Service and Service-Orientation taking into account this broad perspective including Business Service, IT Services, Software Services, Cloud Services and even Human Services.
