7.2BPMN Scope

This International Standard provides a notation and model for Business Processes and an interchange format that can be used to exchange BPMN Process definitions (both domain model and diagram layout) between different tools. The goal of the International Standard is to enable portability of Process definitions, so that users can take Process definitions created in one vendor’s environment and use them in another vendor’s environment.

The BPMN 2.0.2 International Standard extends the scope and capabilities of the BPMN 1.2 in several areas:

•Formalizes the execution semantics for all BPMN elements.

•Defines an extensibility mechanism for both Process model extensions and graphical extensions.

•Refines Event composition and correlation.

•Extends the definition of human interactions.

•Defines a Choreography model.

This International Standard also resolves known BPMN 1.2 inconsistencies and ambiguities.

BPMN is constrained to support only the concepts of modeling that are applicable to Business Processes. This means that other types of modeling done by organizations for business purposes is out of scope for BPMN. Therefore, the following are aspects that are out of the scope of this International Standard:

•Definition of organizational models and resources,

•Modeling of functional breakdowns,

•Data and information models,

•Modeling of strategy,

•Business rules models.

Since these types of high-level modeling either directly or indirectly affects Business Processes, the relationships between BPMN and other high-level business modeling can be defined more formally as BPMN and other specifications are advanced.

While BPMN shows the flow of data (Messages), and the association of data artifacts to Activities, it is not a data flow language. In addition, operational simulation, monitoring, and deployment of Business Processes are out of scope of this International Standard.

BPMN 2.0.2 can be mapped to more than one platform dependent process modeling language, e.g., WS-BPEL 2.0. This International Standard includes a mapping of a subset of BPMN to WS-BPEL 2.0. Mappings to other emerging standards are considered to be separate efforts.

The International Standard utilizes other standards for defining data types, Expressions, and service operations. These standards are XML Schema, XPath, and WSDL, respectively.
