Use the result well

A clear answer, with the assumptions visible

These recommendations turn the result into an operational next step without hiding the inputs behind a score.

  1. 1

    Use a rate from comparable bookings and a recent period.

  2. 2

    Reduce risk with clear reminders and easy rescheduling.

  3. 3

    Plan capacity around impact as well as probability.

How this tool works

  1. Treat each booking as one yes-or-no no-show chance.
  2. Use jStat’s binomial distribution across the entered booking count.
  3. Add the probabilities at and above the chosen threshold.
