  1. Business Process Management (BPM) What is BPM? Why should I care? SOA Brown Bag #4 SWIM Team February 9, 2011

  2. Agenda • Introduction – why should I care? • Definitions • The benefits of BPM • Model-Driven Environment • BPMN and its challenges • DoD Primitives • Adoption Challenges • BPM and SOA • BPEL Orchestration • Key characteristics of BPM Suites • Tools • Getting Started

  3. Business and IT are tightly connected;they either succeed or fail together • Business Process: The required steps to accomplish a specific business function. “Representation of what an organization does -- its work -- in order to accomplish a specific purpose or objective” source: BPMN Modeling and Reference Guide • Business processes that require automation are implemented and facilitated through IT. • As business processes change, IT has to change. Business Processes IT implementation

  4. Processesdrive a “true” SOA • Myth: If you’ve implemented web services, you’ve implemented SOA. • Reality: An organization will reap the full benefits of SOA if it starts with its business process. The reward at the end of the journey

  5. BPM, BPMN & BPEL defined

  6. Additional elements

  7. How does it all fit together? BPM BPMN BPEL Services Layer

  8. What is the benefit of BPM? • To gain sight and control of the business process. • To provide a service orchestration layer in SOA implementation. • To enable business agility.

  9. What is a model-driven environment (MDE)? • Model-Driven Environment (MDE): Models created based on today’s problem and tomorrow’s solution environments. • Models can be created with sufficient specificity to generate the necessary technical artifacts for execution, or can be executed directly in the appropriate run-time environment. • Business Process Automation engine (see next slide) • Business rules engine

  10. How do we get to a model-driven environment? • A BPMN model captures business processes transfers them to a Business Process Automation engine in a BPMN-executable serialization format. • Depending on the tool, it may also be: • Transferred as an XML Process Definition Language (XPDL) format. • Translated into the BPEL specification. • Captured in one of the business rules languages.

  12. BPMN: different conformance subclasses for different uses

  13. BPMN 2.0 Conformance Class

  14. Challenges • There are too many options to accomplish the same results or to diagram the same processes. • Using tools interchangeably is nearly impossible.

  15. Project: DoD Primitives • Using DoD Primitives is a way to establish standard format for diagrams and for data that represents the diagrams, and for data that moves within and between the reality that diagrams represent. • The Object Management Group selects DoD primitives as a BPMN conformance class.

  17. Adoption challenges • Thinking “Process” – True, executable BPM requires a new level of rigor and attention to business processes. • Managing cultural impact – Documenting processes with tools (as opposed to pictures) will illustrate issues with current processes. A socialization strategy is key. • Many popular BPM suites are ‘heavyweight’ and present a non-trivial learning curve.

  18. BPM and SOA Process Flows Coarse-Level Web Services Best Case Scenario

  19. A business-driven SOA, defined “SOA is a way of describing an environment in terms of shared mission and business functions and the services that enable them.”* *Source: DoD Net-Centric Data Strategy

  21. BPEL orchestration • A BPEL orchestration is considered a web service in the domain to which it belongs. • All BPEL processes provide a set of WSDL and schema definition files within the namespace that identifies the domain. • The BPEL WSDL file will provide the binding information and the endpoint of the location where it is deployed. • The orchestration is represented in a WS-BPEL standard representation that should be portable across BPEL engines. • BPEL orchestration service should follow web service invocation standards (WS-I).

  22. BPEL orchestration, continued All orchestrations have one entry point and one response point. • The invocation/entry to the orchestration is marked with the receive block and delivers the message identified as the input parameter in the operation. • Response block must return a message identified as the output parameter in the operation. • A BPEL process may be synchronous e.g., a client needs to receive response immediately, or asynchronous e.g., a client will continue its operation and receive a response at a later time.

  23. BPEL orchestration elements A BPEL orchestration consists of scopes, sequence, partner-links, variables, activities and fault handling. Scope: Identifies the unit of operation within an orchestration. This helps to avoid variable collisions, fault handling and ensuring transaction integrity. Sequence: Identifies a sequence of activities. Partner Links: External services are represented as partner links and they specify the WSDL file of the external service. Partner Links/Adapters: Some BPEL tools provide technology and application adapters that extend basic technologies i.e., databases, queues or applications i.e., CRM, ERP as web services through wizards. Variables: Data stores that hold the operational data within the life of the orchestration. Variables can be localized to a scope or set in the global scope. Activities: Transformations allow copying whole or sub trees of data across variables. Assignments allow specifying values for leaf nodes of an XML tree. Fault handling: Scope errors can be managed using fault handling for a graceful exit as well as for ensuring transactional integrity. Errors with partner link invocations must be handled using fault handling.

  24. Key characteristics of BPM suites • A graphical modeling capability • Ability to simulate business process • Ability to create rules to drive flow and decisions • Ability to capture, present, and analyze process metrics • Standards-based

  25. Getting started • Prototype/Pilot – an area for improvements! • Choose a small, but business-significant process. • Engage the vendor for training, preferably focusing on the pilot problem. • Identify business services required for process support. • “Prototype” the socialization process. • Engage stakeholders to assess feasibility of making candidate process changes illustrated by the modeling process.
