Theory of Constraints
How to use it
Identify the constraint, use it effectively, align other work to it, expand it if justified, then look for the next constraint.
Worked example
If drying constrains mill output, schedule receipts and maintenance around dryer hours before adding intake capacity.
Common pitfall
Improving a non-constraint may increase inventory and waiting without improving total throughput.
- Frame the questionWhich step limits the output the customer actually receives?
- Apply the frameworkUse Theory of Constraints on the worked example above.
- Produce an answerMap the bottleneck and include waiting, rework and handoffs in a proposed test.
