Project Context Diagram and UML/BPMN EAP Profile Overview with Archimate Example
The article explains how a project context diagram maps work packages to organizational elements and describes UML/BPMN EAP profile elements and an Archimate model centered on a DiscountTravelOrderingSite, while also providing contact information for further discussion.
The project context diagram illustrates the scope of work packages as part of a broader transformation roadmap, linking work packages with organizations, functions, services, processes, applications, data, and technology that will be added, removed, or affected.
UML/BPMN EAP Profile
External participant: participants outside the enterprise.
Internal participant: participants belonging to the enterprise.
Requirement: business requirements in this context.
Interaction application component: top‑level component that manages interaction with external IS elements, usually a GUI such as a web interface.
Database application component: a repository; in pure SOA it would not appear, but useful for legacy analysis or technical architecture.
Application: may correspond to a legacy application, off‑the‑shelf product, or an assembly of application components.
System federation: coarse‑grained application component that assembles systems for joint operation, e.g., cross‑company collaboration.
Use case: represents interaction between participants and the system to satisfy a business requirement, further described by scenarios.
Business service: a service offered by the business, which can be realized by one or more IS services.
Business process: detailed in flowcharts (event diagrams) and described in the process diagram.
Information flow: defines any type of information flow between enterprise activity entities (business entities, events, products, informal information, etc.).
Consume link: indicates a participant consumes an IS element (service, operation, application component).
Implementation link: component implementation; an application component implements a specified element such as a business process.
Satisfy link: indicates an IS element satisfies a requirement.
