High performance teams are usually created by good management. If you change the management then bad management can easily undo that. My best managers have been deeply technical people with good people skills, an interest in management, and willingness to get out of the way and no longer make the decisions they made when they were a developer. Management is a lot more than babysitting it generally involves a lot of coordination up and down the organization to ensure the team is doing the right work in terms of organizational and customer priorities. Good management can give you what to work on while leaving you to decide the how.
