Which set of steps involves identifying the constraint, developing a plan, focusing resources, reducing constraint effects, and repeating the process?

• A. Kaizen Improvement Process
• B. Five Steps of the Theory of Constraints
• C. Six Sigma DMAIC
• D. Total Productive Maintenance

Answer: (B)

This question tests how to systematically improve a system by tackling its bottleneck. The steps described map to the Theory of Constraints’ improvement cycle: first identify the constraint that limits throughput, then develop a plan to exploit the constraint so it’s utilized fully, next subordinate everything else to the constraint by focusing resources and aligning processes around it, then elevate the constraint to increase its capacity, and finally repeat the process to tackle the next bottleneck as it appears. This sequence—identify, exploit, subordinate, elevate, and repeat—is the essence of TOC’s approach to continual flow and throughput improvement. Other methods operate differently: Kaizen centers on broad, ongoing incremental improvements across the system; Six Sigma DMAIC follows Define, Measure, Analyze, Improve, Control; Total Productive Maintenance focuses on maintaining equipment to maximize availability. None of these follow the specific bottleneck-focused cycle described here.
