An adjacency diagram that illustrates primary and secondary adjacencies between major work groups or departments.

• A. Process Mapping
• B. Organizational Chart
• C. Value Stream Mapping
• D. Bubble Diagram

Answer: (D)

Visualizing how major work groups relate spatially helps optimize movement and collaboration. A bubble diagram uses simple bubbles for each department and shows which groups should be near each other based on proximity or adjacency. It emphasizes primary adjacencies—the most important pairings for efficient interaction—and secondary adjacencies that are beneficial but less critical. This makes it the best fit for illustrating how departments should be positioned in a facility or workspace during early design. It isn’t about mapping process steps, flows, or hierarchical structures, which are covered by process/value stream maps and organizational charts.
