SOA and Business Process Management

Facilities that a complete BPMS should posses:

    Process Modeling
    Process Execution
    Process Monitoring (low level) and Business Activity Monitoring (high level)
    Infrastructure

Business Process Layer uses the Services layer
  
    * Business Process Layer and Business Activity Monitoring
    * Services layer (LOB services, Technical services, Registry, service level data model,
      service level security model, service level management model, and WS Platform)
    * Application layer (Packaged and Custom)
    * Technology layer (JEE, .NET, Messaging, DBMS, LDAP,..)

Implementing a process layer without a service layer has inhibited the wide spread
adoption of BPM.

Application and Technology Independent Service level data model
An application level data model is application specific
The service model is described with WSDL and WS-Policy and incorporates
the service level data model and qualities of service.

Web Service Orchestration (BPEL) and Choreography (CDL)

The convergence of BPM, SOA, Web services and XML promises to significantly
improve corporate agility, reduce time to market for new products and services,
reduce costs, and improve operational efficiency of IT systems.
