Build collaboration and consensus around a common agenda (quality, patient satisfaction, HCAHPS are excellent consensus-builders):
1. Aggregate and disseminate comparable performance data in a consistently high-energy, accountable, forum
2. Solicit collaboration to increase coordination and reduce inefficiencies
3. Look for people doing things right - and offer sincere appreciation
4. Be candid about the challenges you're facing, and ask for help (then genuinely thank those that provided it, when you achieve your goal)
5. Rediscover your sense of humor!
