The most reliable measurement framework: (1) pre-investment baseline survey measuring noise-related concentration difficulty, voluntary office attendance rate, and peak pod utilisation; (2) 60-day post-investment resurvey measuring the same variables; (3) ongoing utilisation monitoring. For acoustic pods specifically, pod utilisation rate above 70% during peak hours is a signal of both strong demand and ROI realisation — and a trigger for expanding pod capacity to capture additional return. HIGHKA’s 2–4 hour assembly means capacity expansion does not require a construction programme.
