Useful engineering metrics may include work-order volume, repeat service calls, maintenance labor hours, repair costs, room downtime, equipment failure rates, warranty claims, energy consumption, and average time to complete repairs.

Hotels can analyze these metrics by product category, model, installation year, room type, or property. This helps ownership groups identify aging assets, recurring operational costs, and equipment categories that may require future investment.

Engineering data provides valuable evidence for capital planning because it connects equipment performance with operating costs and guest room availability.
