Day 47 / 100 · Estimation & forecasting · Monte Carlo basics

Let your history forecast.

A Monte Carlo simulation replays your team's real past weeks thousands of times to show how long the remaining work is likely to take.

01

Gather history

Items finished per week, over the last 10 to 20 weeks.

02

Count what's left

Remaining items, plus a factor for items that will split.

03

Simulate

Randomly replay past weeks thousands of times.

04

Read percentiles

“85% of simulations finished within 11 weeks.”

Your history is your best forecaster.
