This question aligns with Design and Innovation , specifically the application of Lean methodology in healthcare. Option B (Value stream mapping) is correct because it is a core Lean tool used to analyze and visualize the flow of processes, identifying steps that add value and those that create waste. In healthcare, value stream mapping helps teams understand patient flow, reduce delays, eliminate inefficiencies, and improve care delivery. Options A (mystery shopping), C (experience diagramming), and D (community interviewing) are not central Lean tools, although they may support broader experience improvement efforts. CPXP principles emphasize using structured methodologies like Lean to redesign care processes with a focus on efficiency, quality, and patient-centered outcomes, making value stream mapping a foundational component.
