What's the Difference Between Constraints and Bottlenecks?
Claudio Castanon
Constraint and bottleneck are different concepts:
- A constraint is a restriction of a process, it might be, equipment, people, specifications, materials, enviroment, policies, suppliers.
Being a restriction, these constraints do not allow to meet the customer demand or any other customer key requirement by not being "capable" (in terms of capacity).
For the whole process to flow as expected in order to obtain a daily production rate versus customer demand you can not produce or sell more than the constraint is capable to give.
Do not let a constraint dictate your throughput, fix the constraint to meet the desired throughput, once you have fixed the internal constraints, be prepared to meet the mother of all constraints: the market.
- A bottleneck on the other hand is simply caused by bad management of a process.

I will point out that even if we have a "market constraint", we still need an internal management tool to pace production at the market demand rate. T...Sign up

Is the Market the Real Constraint?
