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

    Update the forecast each month with the newest completed data.

  2. 2

    Keep one-off closures and unusual campaigns visible beside the forecast.

  3. 3

    Plan capacity from the lower and upper range, not only the middle estimate.

How this tool works

  1. Parse the history with Papa Parse.
  2. Fit a simple linear trend with simple-statistics.
  3. Show the trend as a range, not a promise.
