YES.
Seriously...just not in "6" months. It takes micro changes over time, it takes SOFT-SKILLS training, scaled, on people's phones, using AUDIO and INFO-GRAPHICS, with repetition. "An organization is the length and shadow of its leader" (not the Board). Peter Drucker wrote that over 60 years ago (I added: "not the Board"). It takes
"enter-TRAINment mini-ZOOMs" with heterozygous (opps...I mean heterogeneous, personnel from different pay-scales seeing each others faces' LIVE repeatedly). And most of all, it is EXECUTING ACCOUNTABILITY (translation: measurement) all the way down to the lowest job in your hospital. (and ... NOT in your hospital: APPS, software, NEW MACHINES, sale reps, suppliers...)
So, "YES," you should hire an external "previous leader" to shake up your status quo. My task is to CONSULT my way out the door!
