Are we sure about that? Why would they not be?

Subject: [soa-rm] Definition of Service:From concall

hi all

On todays call I was trying to present my definition of what a service is. If I had a whiteboard

Org has Translates Digitized

Need Task + wire enable = Service

Capability

Start from the perspective that an org has a need (or is offering a capability). That need gets translated into a task, eg get an airline seat [which is a finer granularity; or an activity, make a trip reservation, which is more complex] The task has to have technical details added to allow it to be provided and/or consumed. The end result is a service in the context of our work for SOA.

A service is based on the functionality it is providing. That functionality is not just the business (or mission) task/activity but the digital requirements, eg encryption, endpoints. A service is multi faceted.

From this perspective shoe shining and food delivery are not services. So a logical conclusion is that 'services' are not absolute.
