Periodically, boards should take their temperature. To do so, at an open board meeting, ask each board member to place a checkmark somewhere along the line between the two columns, then open the conversation about those areas where the perception is that we should move more to the right than where we are.
Trustees assume quasi-administrative roles.
Recruitment to board is haphazard. The healthy board not only finds itself in the right column but periodically does a health check to see where improvements are needed.
