What type of flowchart focuses on representing the flow of tasks or activities between individuals or departments?

The correct choice for identifying the type of flowchart that focuses on representing the flow of tasks or activities between individuals or departments is a swimlane diagram.

A swimlane diagram is designed specifically to delineate responsibilities and interactions across different departments or individuals by organizing the flow of processes into "lanes." Each lane represents a different actor or department, thereby clearly illustrating who is responsible for each task throughout the process. This organization helps to highlight handoffs and responsibilities, ensuring clarity in how activities flow from one party to another.

While a deployment flowchart also represents processes, it is generally more focused on the specifics of a process deployment rather than the responsibilities of departments or individuals. A workflow diagram depicts the sequence of tasks in a process but may not emphasize the organizational roles as distinctly as a swimlane diagram. A process map, meanwhile, provides a broader overview of a process flow and typically does not highlight individual responsibilities in the same structured way.

Therefore, the focus on task flow between individuals or departments aligns exclusively with the structure and purpose of a swimlane diagram.
