A Choreography is an ordering of Business Activities within a Business Collaboration.
The purpose of a Choreography is to specify which BTA, Complex Business Transaction Activity and/or Collaboration Activity should (are expected to) happen
As a result, the specification of choreography definition and the Business Transaction protocol defines unambiguously which business message (DocumentEnvelope or Business Signal) is expected by any of the parties

The choreography is specified in terms of Business States, and transitions between those Business States
When a transition is validated:
- it does not mean that the target Business Activity would start immediately
- it means that the Business Activity is “enabled” and the initiating party MAY now send the request whenever appropriate, provided that it remains within the TimeToPerform of the Binary (Business) Collaboration
It is merely the execution of the backend systems, which instruct the BSI (Business Service Interface) to send or receive messages that advance the state of a collaboration
There is no execution engine associated to the collaboration itself.

The Business Collaboration is either in the state of performing a given Business Activity (or multiple concurrent Business Activities) or waiting to start a Business Activity, unless it has reached a completion state
Once a Business Activity completes a transition from this Business Activity, it navigates to another Business Activity
A business message initiates a Business Collaboration or advances its state
