This matrix diagram is an essential planning tool for architects and facility managers designing a medical or laboratory facility. It categorizes rooms by their function, such as bacteriology, clinical microscopy, and drug testing, and uses color coding to indicate four types of spatial relationships: direct adjacency, convenient adjacency, distant adjacency, and no spatial relation. The strategic placement of these rooms is crucial for efficient workflow, staff efficiency, and patient care. This visualization aids in creating an environment that supports clinical operations and enhances the accessibility between related departments.
