The Flow Forecasting Pocket Guide

A practical guide to delivery forecasting using Monte Carlo Simulation. Ditch averages, see risks early, and make smarter decisions with your existing data.

This guide challenges the myth of perfect prediction and shows you how to make smarter decisions in the face of uncertainty. You’ll learn why averages fail us, how to interpret variability in your system, and how to apply Monte Carlo Simulation using just a spreadsheet and your team’s past throughput. With practical examples, blunt honesty, and a clear disdain for overcomplication, this book gives you the tools to see delivery risk earlier and respond with confidence—without estimates, story points, or time-consuming planning sessions.
