Continuous Requirement Changes

Problem Dimensions

Business Process Management Domain Specific languages. BPM Definition. BPMN 2.0. Service Orchestration (PBEL).

Domain Specific languages. domain-specific language (DSL) is a programming language or specification language dedicated to a particular problem domain,programming languagespecification language

BPM Definition Business process: A procedure that describes how people and systems work together Business Process Management (BPM): Optimizing efficiency by automating,analyzing, describing and improving business processes

Traditional BPM approach

Collaboration Common Language

BPM Key Features Common Communication language. Graphically visualized process. Separation of concerns. Ease of Development and deploy. Ease of change and reuse Reduced development time/Time to Market.

Key Functions Workflow delivers the following functionality Automation of processes Routing and scheduling of activities Process visibility Process control through escalations and notifications Tracking of activities Collaboration of all parties involved Convergence of process and information Redesign of business processes

BPMN 2.0 (business-oriented notation) Business Process Modeling Notation (BPMN) is a graphical representation for specifying business processes in a business process model.graphical representationbusiness processesbusiness process model The objective of BPMN is to support business process management for both technical users and business users.

Service Orchestration (BPEL) Business Process Execution Language (BPEL) is a XML-based language used to define enterprise business processes within Web services. Service orchestration is to be seen in the context of an Enterprise Service Bus. An enterprise service bus is a central communication backbone on a corporate level. It integrates many diverse systems and it is based on XML technology.

Service Orchestration (BPEL ):Example Example Suppose you have services A, B and C on your enterprise service bus. Service orchestration is a graph based execution language for writing a new services as a function of existing services. E.g. A new service D can be written as a function of existing services A, B and C in an orchestration script.
