Which characteristic is common to both Lean and Six Sigma methodologies?

The characteristic that is common to both Lean and Six Sigma methodologies is the use of systematic problem-solving tools. Both approaches integrate a structured framework to identify, analyze, and address inefficiencies or defects in processes. Lean focuses on eliminating waste and ensuring smooth flow, while Six Sigma aims to reduce variation and improve quality. Systematic problem-solving tools, such as root cause analysis, process mapping, and statistical analysis, are fundamental in both methodologies to achieve their respective goals of efficiency and quality improvement.

Using systematic tools helps teams diagnose issues effectively and develop sustainable solutions. This shared approach reflects the foundational idea that improving processes requires an organized method to uncover and solve underlying problems, making it an essential characteristic of both Lean and Six Sigma. Other options, while relevant to one methodology or the other, do not capture this shared practice as effectively. For instance, maximizing throughput is more aligned with Lean, whereas relying heavily on statistical analysis might lean more towards Six Sigma.
