Which tool is often used to streamline processes by reducing waste?

The Lean methodology is specifically designed to streamline processes by identifying and eliminating waste, thereby increasing efficiency. It focuses on maximizing value for customers by reducing unnecessary steps in a process, which not only enhances productivity but also minimizes costs and improves quality. Lean principles can be applied in various industries, including healthcare and oncology, to ensure that every aspect of a process adds value and contributes to patient care.

DMAIC (Define, Measure, Analyze, Improve, Control) is a data-driven improvement cycle used primarily in Six Sigma projects, which focuses more on quality control and process improvement rather than specifically on waste reduction. While it may contribute to efficiency, its primary goal is different from that of Lean.

A Run Chart is a simple graphical representation used to display data over time, which helps in analyzing trends and variations but does not inherently reduce waste.

The PDSA (Plan-Do-Study-Act) cycle is a problem-solving approach that supports continuous improvement but is more focused on testing and refining changes rather than exclusively targeting waste reduction.

Thus, Lean is the correct answer as it directly addresses the goal of streamlining processes through the reduction of waste.
