Which management approach focuses on identifying and improving system constraints?

• A. Lean Manufacturing
• B. Total Quality Management
• C. Theory of Constraints
• D. Six Sigma

Answer: (C)

The idea being tested is identifying the part of the system that limits overall performance and then lifting that limit. The Theory of Constraints centers on the notion that a system’s throughput is governed by its most restrictive element—its bottleneck. By finding that constraint and working through a focused process—first exploiting the constraint, then subordinating the rest of the system to its needs, and finally elevating the constraint—you raise the entire system’s capacity. Once you’ve improved the current bottleneck, you look for the next one and repeat, iterating to continually improve overall flow. This approach is distinct from Lean Manufacturing, which concentrates on eliminating waste and improving flow; Six Sigma, which targets reducing variation and defects; and Total Quality Management, which emphasizes broad cultural quality improvement.
