Business process definition

• A process is a specific ordering of work
  activities across time and place, with a
  beginning, an end, and clearly defined inputs and
  outputs a structure for action1. Business
  processes are both internal and external to
  autonomous business entities, and drive their
  collaboration to achieve shared business goals by
  enabling highly fluid process networks. Such
  business goals include end-to-end efficiency,
  transformation empowerment, and value management.

Business process

• Business processes are adaptive structures for
  action through which many participantsIT
  systems, applications, users, partners, and other
  processesplay a variety of roles. Business
  Process Management enables the collaboration of
  such participants in a reliable, scalable, and
  secure manner, by supporting dynamic process
  topologies that allow the boundary between
  processes and participants to be determined
  on-the-fly by long-term and real-time business
  goals, while retaining synchronized public
  interfaces associated with trading partner
  agreements.

BPEL

• l The ltcontainersgt section defines the data
  containers used by the process, providing their
  definitions in terms of WSDL message types.
  Containers allow processes to maintain state data
  and process history based on messages exchanged.
• l The ltpartnersgt section defines the different
  parties that interact with the business process
  in the course of processing the order. The four
  partners shown here correspond to the sender of
  the order (customer), as well as the providers of
  price (invoiceProvider), shipment
  (shippingProvider), and manufacturing scheduling
  services (schedulingProvider). Each partner is
  characterized by a service link type and a role
  name. This information identifies the
  functionality that must be provided by the
  business process and by the partner for the
  relationship to succeed, that is, the portTypes
  that the purchase order process and the partner
  need to implement.
