An improvement team is presented with the following information and tasked with deciding which improvement...

The data and staff comments highlight inefficiencies, non-value-added steps, delays, and waste in the medication order-to-arrival process, suggesting a need for process optimization.

Option A (Poka-yoke): Poka-yoke is a Lean tool for mistake-proofing specific steps, not a broad methodology for process overhaul.

Option B (Plan-Do-Study-Act): PDSA is a general improvement cycle, effective for testing changes but not specifically focused on eliminating waste.

Option C (Six Sigma): Six Sigma reduces variation using DMAIC, but the comments emphasize waste and inefficiency, not variability.

Option D (Lean): This is the correct answer. The NAHQ CPHQ study guide states, “Lean methodology focuses on eliminating waste, streamlining processes, and removing non-value-added steps, making it ideal for addressing inefficiencies like those in medication delivery” (Domain 4). Comments about complicated processes, redundant systems, delays, and overproduction align with Lean’s focus on waste reduction.

CPHQ Objective Reference: Domain 4: Performance and Process Improvement, Objective 4.3, “Select improvement methodologies,” emphasizes Lean for waste elimination. The NAHQ study guide notes, “Lean is best for processes with inefficiencies and non-value-added steps” (Domain 4).

Rationale: Lean directly addresses the identified issues of waste and inefficiency, aligning with CPHQ’s improvement principles.
