Hotels should measure technology upgrades using both operational and guest-facing KPIs. Common examples include service ticket volume, out-of-order room impact, streaming or connectivity complaints, guest satisfaction feedback, energy usage, repair frequency, and replacement costs over time. For revenue-related projects, hotels may also track review trends, repeat stays, or upsell performance where signage or guest-facing technology is involved. Tracking results after installation helps prove value and guides future purchasing decisions.
