Which methodology includes both the identification of waste and the implementation of continuous flow?

Lean Six Sigma is a methodology that specifically targets waste reduction and promotes continuous flow of processes. It integrates principles from both Lean manufacturing, which focuses on eliminating waste and enhancing process efficiency, and Six Sigma, which aims at reducing variation and improving quality. By combining these approaches, Lean Six Sigma not only emphasizes the identification of unnecessary steps or resource consumption (waste) in processes but also implements strategies that ensure products and services flow smoothly through the system, thereby enhancing overall operational effectiveness.

The other options do not encompass both aspects as effectively. DMAIC is a structured problem-solving process typically used in Six Sigma projects aimed at improving existing processes, but it does not specifically target waste identification or flow in the Lean context. Similarly, MAIC is a variation of DMAIC but also does not focus on the Lean principles of waste reduction and continuous flow. Quality Assurance mainly focuses on ensuring that processes meet certain standards and does not inherently incorporate waste identification or continuous flow methodologies in the same way Lean Six Sigma does.
