How far do you walk just relaying requests?
Every time a request gets relayed by word of mouth, someone walks it there and back. Enter your number of beds: requests per resident, minutes of walking per request (5 by default) and five shifts a week are pre-filled from cautious estimates, and editable. The result is your whole team's combined walking, shown in marathons a year.
These are upper estimates you adjust to your own building, not a study. Buttonworks routes a request straight to the right team the moment it's sent. See also the time-cost calculator.
