This question aligns with Design and Innovation , particularly process improvement methodologies such as Lean. Option D is correct because “going to Gemba” is a core Lean principle that means going to the actual place where work occurs to directly observe processes, identify inefficiencies, and understand real conditions. This approach supports data-driven, frontline-informed improvement and is fundamental to eliminating waste and improving value. Option A reflects patient-centered care but is not specifically a Lean method. Option B contradicts Lean principles, which focus on reducing unnecessary steps , not adding them. Option C relates to strategic planning rather than process improvement methodology. CPXP emphasizes Lean thinking as a way to design efficient, patient-centered systems , with Gemba observation being a critical first step in meaningful improvement.
