Do you think it would be helpful to know if one of your directors serving on a board was about to leave?
If so, pay attention. According to a recent study, prestige, the ability to have influence over others, and identification with the director role decrease the chance of a director leaving a large firm, while the extent of the time commitment increases the chances of a director leaving.
Since an ounce of prevention is worth a pound of cure, it may be prudent to keep an eye on these variables in order to anticipate and execute succession planning of board members.
