What is a benefit of using swim lanes in a process model?

Using swim lanes in a process model is beneficial because they provide a clear visual representation of roles and responsibilities within the process. This visual distinction helps stakeholders easily identify who is responsible for each part of the process, enhancing clarity and communication. By organizing activities into separate lanes for different roles or teams, it becomes evident how each role interacts with others, allowing for better management of workflows and responsibilities. This structure is particularly useful in complex processes where multiple roles are involved, ensuring that accountability is clearly defined.

The other options do not correctly capture the primary advantage of using swim lanes. Increasing the number of process steps does not inherently arise from using swim lanes; rather, the complexity of the process may determine the number of steps needed. While swim lanes can help in organizing data by providing context for where and how data is used, they do not inherently facilitate the storage of more data. Additionally, swim lanes do not eliminate the need for start and end nodes in a process model, as these elements are essential to define the boundaries of the process itself.
