Domain 1A Healthcare Systems And Settings Practice Test

Lean and Six Sigma focus on improving how work gets done by removing waste and reducing variation, with the goal of delivering safer, faster, and more reliable care. In healthcare, this means applying systematic, data-driven methods to both clinical and operational processes—things like patient flow, scheduling, handoffs, medication administration, and lab turnaround times. By eliminating non-value-added steps (Lean) and tightening process variation (Six Sigma), organizations can improve quality, safety, and patient outcomes while also lowering costs and improving efficiency. These approaches are not limited to manufacturing; they’re widely used in healthcare to support better decisions and standardized, reliable processes. They also supplement clinical judgment rather than replace it—the clinicians still decide what care is appropriate, but the pathways and workflows that deliver that care become more predictable and less prone to error. The statement best capturing this is that Lean and Six Sigma are used to eliminate waste and reduce variation, improving quality and efficiency in clinical and operational workflows.
