Vantaggi
Efforts on the part of HR to build a positive culture were one of the best experienced in more than 20 years of professional experience. This resulted in an impressive array of team members - many of whom I would actively seek out to be on future teams.
Svantaggi
Executive management suffers from "smartest people in the room" syndrome. That sought from team members at all levels is simply execution. Any debate / discussion that may have occurred came to be understood as largely pro forma as decisions almost invariably were pre-determined. While this may have made for streamlined decision making it did not result in optimal outcomes. Further, the practice served to undermine the sense of being a valued team member. There was a clear delineation between those deemed trusted and therefore worthy of being listened to and those who were not.
