What type of diagram typically outlines the interactions between various stakeholders?

A swim lane diagram is specifically designed to illustrate the interactions and responsibilities among various stakeholders in a process. This type of diagram organizes tasks into lanes, which represent different participants or departments, allowing for a clear visual representation of who is responsible for each part of a workflow. By mapping out processes in this manner, it effectively highlights how different stakeholders interact and collaborate, making it easier to identify handoffs, dependencies, and potential bottlenecks in the system.

In contrast, a class diagram focuses on the static structure of a system by showing classes and their relationships, which does not convey interaction between stakeholders. A Gantt chart is primarily used for project scheduling, showcasing the timeline and duration of tasks rather than stakeholder interactions. A flowchart depicts the sequence of steps in a process but lacks the explicit separation of roles that a swim lane diagram provides, making it less effective for illustrating stakeholder interactions.
