Which notation helps visualize workflow across different stakeholders and responsibilities?

Swim lane notation is specifically designed to illustrate workflows by dividing them into lanes, each representing different stakeholders or responsibilities. This visual representation helps clarify who is responsible for each part of the process, making it easier to understand the interaction and flow of tasks among various participants. By organizing processes in this manner, stakeholders can quickly identify roles and responsibilities, highlighting accountability and collaboration in workflow scenarios.

The other options serve different purposes. Business Process Model Notation (BPMN) provides a comprehensive way to model business processes but is not primarily focused on distinguishing responsibilities among stakeholders like swim lane notation is. Event-driven process chain (EPC) is more suited for depicting processes and events within a business context, often focusing on how one event triggers another rather than explicit responsibilities. Unified Modeling Language (UML) is primarily used for software design and does not inherently emphasize stakeholder responsibilities in workflows. Each of these forms of notation has its unique advantages, but swim lane notation is particularly effective for visualizing interactions and responsibilities in collaborative environments.
