By definition, one-quarter of boards are in the top quartile of high-performance boards and 25% are in the bottom quartile.
There have been plenty of occasions when a board in the top quartile of high-performance boards fell out of the top quartile in a subsequent year. Similarly, boards in the bottom quartile have climbed into the middle two quartiles or even into the top quartile within a couple of years with a determined effort.
We also provide between three and five recommendations to boards, no matter how good or bad they are. Those recommendations are designed to ensure the most significant possible increase in the board’s effectiveness and, in the case of a high-performance board, to retain such high performance.
