Business process management (BPM) addresses how organizations can identify, model, develop, deploy and manage business processes involving IT systems and human interaction, with goals of reducing mismatch, increasing productivity and flexibility while reducing costs. Basic components of a business process management system (BPMS) include data, service, and process modeling as well as composite web services composed of atomic web services to implement business processes available to internal and external users. Two languages, BPEL for orchestration and CDL for choreography, specify the composition of atomic and composite services.

• BPM addresses how organization can identify, model, develop,
deploy, and manage their business processes that involve IT systems
and human interaction.
• Goals:
• Reduce mismatch
• Increase employee productivity
• Reduce operational costs
• Increase agility
• Flexibility
• Reduce development costs

specifications
• Two languages:
• Business process execution language(WS-BPEL)
• Choreography description language(WS-CDL)

14. WS-BPEL
• Basic tasks:
• Invoke task
• Receive task
• Reply task
• Wait task
• Assign task
• Throw task
• Terminate task
• Structured tasks:
• Sequence task
• Switch task
• Pick task
• While task
• Flow task

15. Example of web services composition
Two approaches:
• Orchestration – centric
• Choreography - centric
