Theory of Constraints / Bottleneck
Updated 2026-08-22
INTRODUCTION
English translation pending.
CORE DEFINITION
Eliyahu Goldratt set out the theory of constraints in his book The Goal. It holds that every system has at least one constraint that limits its throughput, and that improving non-constraint stages produces no increase in output while adding cost and inventory. The core claim is that a chain is as strong as its weakest link, so effort should concentrate on the constraint until it is broken. The qualification is that the constraint moves once it is relieved, so the analysis is continuous rather than a one-time fix.
SCAFFOLDING EFFECT
Reduce cognitive load
- Bottleneck hunt: find the stage whose capacity sets the ceiling on total output. - Effort redirect: stop improving stages that already exceed the bottleneck's processing rate. - Subordination rule: pace all other stages to the bottleneck's rate rather than to their own capacity.
Anchor fast decisions
Throughput cannot exceed the rate of the slowest stage, so work released faster than the bottleneck can process simply accumulates as inventory. That inventory consumes cash and hides quality problems without adding output, which is why local efficiency at non-bottleneck stages is worse than neutral. Concentrating improvement on the constraint raises the ceiling, and relieving it moves the constraint to a new location.
