Re: [soa-rm-ra] So What is a Service Ecosystem Anyway?

An example of such 'holistic perspective' is a Service Description of the composite/aggregate service that has to encapsulate (somehow) business functionality of engaged services as well as their RWE and SLA. The composite/aggregate service adds some functionality, which is invisible within simple decomposition and analysis of separate (engaged) services.

In section 1.2, we took the definition Rex provided and worked it down to:

"Many systems cannot be understood by a simple decomposition into parts and subsystems – in particular when there are many interactions between the parts. For example, a biological ecosystem is a self-sustaining association of plants, animals, and the physical environment in which they live.  Understanding an ecosystem often requires a holistic perspective rather than one focusing on the system's individual parts."

I agree with Frank that we do not define how it has to be done, but rather provide understanding and predict how it will be done.
