Identifies the data and users involved in each step.

• A. Data Usage Diagrams
• B. Dataflow Diagrams
• C. Swim Lane Model
• D. Data Source

Answer: (C)

The ability to map a process by who performs each step and what data they use at that step is best shown by the Swim Lane Model. In a swim lane diagram, each lane represents an actor, role, or system, and the process steps are placed within the lanes that are responsible for them. This layout makes it immediate to see, for every step, which user or unit is involved and which data items flow through or are produced at that moment. It directly highlights responsibilities and data interactions across the end-to-end process, which is exactly what identifying the data and users involved in each step requires.

Dataflow diagrams focus on how data moves between processes, stores, and sinks, rather than who is performing each step or owning the data at that step. Data sources point to where data originates, not to the per-step involvement of users or systems. Data usage diagrams aren’t a standard, well-established way to map responsibilities per step. So the Swim Lane Model best fits the need to identify both the data and the users involved at every step of the process.
