项目上下文图显示了作为更广泛的转型路线图的一部分来实现的工作包的范围。项目上下文图将工作包与将被添加、删除或受项目影响的组织、功能、服务、过程、应用程序、数据和技术联系起来。项目环境图对于项目组合管理和项目动员也是一个有价值的工具。
UML/BPMN EAP Profile
External actor: An actor that is external to the enterprise.
Internal actor: An actor that belongs to the enterprise.
Requirements: In this context, these are business requirements.
Interaction application component: Represents the top level components that manage the interaction with elements outside the IS. In most cases, it is a GUI component, such as here a web interface.
Database application component: Represents a repository. In pure SOA architecture, these elements should not appear. However, for legacy analysis or technology architecture, modeling repositories or repository deployment can be useful.
Application: This application component corresponds to legacy applications, off the shelf products, or can be an assembly of application components.
System federation: A system federation is the coarser-grained application component. It assembles systems to federate them, such as in the example of cooperation between different information systems between different companies.
Use case: Represents an interaction between an actor and the system, in order to fulfill a business need. A use case is further described by a set of scenarios that express the interactions between the system and the actors.
Business service: Represents a service provided by the business, which may then be realized by one or more IS services.
Business process: As presented in process maps (event diagrams). The business process is detailed in flow diagrams.
Information flow: dDefines the flow of any kind of information (business entity, event, product, informal, etc) between active entities of the enterprise.
Consumes link: Expresses that participant (e.g. an actor) consumes an element of the IS (service, operation, application component).
Realizes link: Component realization. An application component realizes the designated element, for example a business process.
Satisfy link: Expresses that an element of the IS satisfies a requirement.
