Follow the rules or don't call it value analysis. Most healthcare organizations will say they are doing value analysis, but what they are really doing is GPO contract evaluations, price shopping, standardization, or product evaluations. This is not value analysis!
You can’t hold people accountable if they don’t know what they are being held responsible for, answerable for, or expected to accomplish. This is why you need to measure results utilizing the tools of benchmarking. Then you will know how much supply savings is achievable at your healthcare organization not only globally, but by commodity group, service line, and SKU (stock keeping unit). This way your project managers will know with certainty how much savings they are responsible for squeezing out of any project they are working on (e.g., orthopedics, pacemakers, dressings, trays, etc.).
