I hear this lament all too often from boards and CEOs. Knowing when to pull the trigger on executive changes is typically very difficult and it is just as frequently a decision that, in retrospect, many will say they should have made "months ago". Knowing that Henry Kravis struggles with this should provide some solace, yet it still doesn't make the decision any easier. Eliminating emotion from business decisions is typically good advice, yet this is one business decision where that is much easier said than done. Also - CEO and other executive team changes are highly disruptive to the organization, so our natural reflex is to try to make do in order to avoid that disruption.
