A Business Collaboration is a set of roles interacting through a set of choreographed Business Transactions by exchanging Business Documents. A Business Collaboration is defined by the parties in the collaboration; it can be simple or complex, it can include expected and unexpected (but contingent) actions and the collaboration can allow for other than eBusiness options. The ebBP technical specification is used to specify the business process parameters to configure the Business Service Interface (BSI) needed to execute and to monitor the collaborations, including the capability to transition to human interactions or decisions that may be important to eBusiness activity, e.g. a phone call.
