Four metrics: (1) Pod and meeting room utilisation rates (booking data or sensor data) — are spaces consistently oversubscribed, suggesting insufficient capacity, or underused, suggesting a size or location mismatch? (2) Employee survey on collaboration quality — specifically, whether employees feel they can access suitable space for both focused individual work and collaborative discussions. (3) Meeting quality indicators — average meeting duration, percentage of participants rating meetings as productive. (4) Cross-functional project velocity — how quickly do multi-team projects advance from initiation to delivery? All four metrics shift measurably when the physical environment is improved to support both collaboration and focus.
