What this model assumes

This is a simple capacity model, not a forecast. It assumes an unlimited supply of identical tasks, eight working hours, immediate handovers, consistent quality and no rework or start-up delay. Each stage can process only what the previous stage supplies. Completed work is limited by the smallest capacity.

Real work also involves interruptions, changing demand, varied complexity and mistakes. Use this model to ask where the work might accumulate, then observe your actual workflow.
