Which process model notation helps identify hand-offs in a process?

The swim lane diagram is particularly effective for identifying hand-offs in a process because it visually organizes activities into distinct lanes, each representing a different participant, department, or role involved in the process. This layout clearly delineates who is responsible for each step, making it easier to spot where transitions occur between different stakeholders or phases of the process. By highlighting responsibilities in this manner, swim lane diagrams help teams understand the flow of activities and the points where hand-offs happen, which is crucial for analyzing efficiency and ensuring accountability.

In contrast, flowcharts focus more on the sequence of steps in a process without necessarily showing who performs each step. Data flow diagrams primarily illustrate how data moves between processes and storage, concentrating on the flow of information rather than on the roles involved. Timing diagrams, while useful for representing the timing of events, do not typically provide clarity about roles or hand-offs, making them less applicable for this specific purpose.
