Roll for Six

A five-person project where every task is rolling a six. Commit your estimate, then see what deadlines do to a project, and how Critical Chain finishes earlier with a single project buffer.

What you’ll learn

Estimates are probabilities. Rolling a six usually takes about 4 rolls, but sometimes 20. Ask someone to commit, and they’ll quote the 20: estimate + commitment = padded estimate.
Safety inside tasks gets wasted. With task deadlines, late finishes are passed on and early ones aren’t, so the project gets longer, not safer.
Pool the safety. Plan each task at its 50% time and put half the removed safety into one project buffer at the end.
Run projects like a relay race. Pass work on as soon as it’s done, ask “how many days do you still need?” every day, and send help to tasks that drag.

Based on the dice estimation game Mohit uses when teaching Critical Chain Project Management.
