Description

Jason introduces the concept of variation as a core production law: the more a project deviates from its established plan, the longer it will take. He walks through a real ripple-effect example, a concrete crew's plan changing mid-task, to show how one small decision can trigger 15 or more downstream disruptions, from returning materials to rerouting crews to reordering supplies. His core message: variation itself is the enemy, alongside waste, and the job of foremen and superintendents is to protect day-level and week-level plans once they're set, holding the line against unnecessary changes so crews can actually execute what was planned.

What you'll learn in this episode:

• The production law of variation: the more a plan changes, the longer the overall project duration becomes
• A real example showing how one small mid-task change can ripple into 15 or more downstream disruptions
• Why day plans especially should be protected from variation once established, so crews can execute without disruption
• Why variation (alongside waste) is framed as "the enemy" in construction production, not just an occasional inconvenience
• The core response to variation: plan ahead, prepare the work, and hold the line on established day and week plans

How much of your project's schedule slippage is really coming from waste, versus from variation, changes and disruptions to plans that were already set?
