What type of diagram would be used as a visualization method in workshops?

Context diagrams are particularly effective as visualization methods in workshops because they provide a high-level overview of how a system interacts with external entities, such as users, stakeholders, or external systems. These diagrams help participants understand the boundaries of the system being discussed, clarifying what is within the system's scope and what is outside it. This clear delineation is beneficial during workshops, where collaborative discussions may be focused on gathering requirements or identifying stakeholder needs.

By using context diagrams, facilitators can engage participants by visually presenting how different components of a system fit together. This aids in ensuring that everyone has a shared understanding of the system's context and can contribute meaningfully to the workshop discussions. The visual nature of context diagrams simplifies complex interactions, making them accessible to all attendees, regardless of their technical expertise.

On the other hand, while mental maps can help organize thoughts, they are more informal and less structured, making them less suitable for workshop contexts. Flowcharts are used to represent processes in a linear way, which may not capture the broader system context effectively. Bar charts are useful for displaying quantitative data but do not provide the holistic view necessary for understanding system interactions in workshops.
