Three measurement approaches in combination provide reliable tracking: (1) add 3–4 acoustic environment and privacy questions to your next engagement survey pulse (before and 90 days after deployment); (2) track pod utilisation through booking system data — consistently high utilisation rates (>70%) indicate that employees value and use the spaces, which is correlated with wellbeing benefit; (3) monitor absenteeism rates in the 6 months following deployment against the prior 6-month baseline — absenteeism is a sensitive measure that typically responds to wellbeing improvements within this timeframe.
