Contrasting Theory of Constraints and Lean Manufacturing
The Theory of Constraints and Lean Manufacturing are both systematic methods for improving manufacturing effectiveness. However, they have very different approaches:
- The Theory of Constraints focuses on identifying and removing constraints that limit throughput. Therefore, successful application tends to increase manufacturing capacity.
- Lean Manufacturing focuses on eliminating waste from the manufacturing process. Therefore, successful application tends to reduce manufacturing costs.
Both methodologies have a strong customer focus and are capable of transforming companies to be faster, stronger, and more agile. Nonetheless, there are significant differences, as highlighted in the following table.
