Which notation can effectively model both high-level processes and detailed workflow?

The Business Process Model and Notation (BPMN) is the most effective notation for modeling both high-level processes and detailed workflows. BPMN provides a standardized set of symbols and notations that can easily convey complex processes in a way that is understandable to all stakeholders, including business analysts, technical developers, and business users.

BPMN's design allows for different levels of detail; it can illustrate a broad overview of business processes at a high level while also offering the capability to drill down into more specific aspects of a workflow. This dual capability makes BPMN versatile for documenting various processes within an organization, allowing teams to maintain a comprehensive view without losing track of detail.

In contrast, while flow charts provide a simpler way to represent processes, they often lack the sophistication needed for complex workflows. Event-driven process chains (EPC) play a useful role in linking events to processes but do not offer the same level of detail and clarity that BPMN provides across multiple perspectives. Unified Modeling Language (UML) is primarily used in software engineering for system modeling and does not focus specifically on business processes, making it less appropriate for this purpose compared to BPMN. Therefore, BPMN stands out as the most suitable choice for someone looking to model processes at multiple
