Fivemodel

Fivemodel is a term used in multiple disciplines to describe a modeling framework that represents a complex system by five interconnected components. There is no universal standard for what the five components must be; the term emphasizes modular decomposition to aid understanding, communication, and analysis.

Common component sets include: (1) actors or users; (2) data or information; (3) processes or behavior; (4) technology or infrastructure; (5) governance, constraints, or environment. Depending on the domain, names and emphasis may vary, but the five-part structure remains the core idea.

Applications of fivemodels appear in fields such as software architecture, business process management, information systems design, and organizational modeling. In software architecture, a five-layer mapping is sometimes used: presentation, application logic, domain model, data storage, and integration with external systems. In business and organizational design, the model helps align user needs, data flows, workflows, technology assets, and regulatory or policy constraints.

Development and evaluation of a fivemodel typically focus on coherence, interoperability, and scalability of the five components. Benefits include clearer boundaries between concerns, improved cross-functional communication, and easier reuse of components. Limitations include potential oversimplification of complex interactions and varying terminology across domains, which can hinder cross-domain comparison or adoption. Overall, fivemodels function as descriptive tools rather than prescriptive standards, adaptable to context and purpose.
