Poduck Regional Medical Center has decided to build a new wing for its outpatient services. Poduck wants to know which services are important to its patients in this new wing. Do they prefer large waiting rooms for family members or small rooms adjacent to recovery rooms? Do they prefer patient advocates to keep them informed or would nurses be better? What technique would be appropriate to come up with weights and tradeoffs for these types of services? Explain why the technique you recommend is best.
