This post is the final installment of a five-part series on best practices in CEO succession. The purpose of the series is to share some of the insights I’ve gained while helping companies manage the messy, sometimes confusing terrain of CEO succession.

Question 5: When Should Planning Begin, and What Time Horizon Should Be Considered?
As I mentioned before, succession planning should be an ongoing process. For firms that don’t have a planning process in place, starting tomorrow is not too soon. A CEO transition is among the most significant, broad-reaching changes for any organization. This sort of change has an effect on every constituent (customers, employees, board members, shareholders, etc.). As such, the potential for error is large and the consequences can be significant. So get out your scout hat and be prepared. Start NOW.
But what time horizon makes sense?
leaders rely on feedback from other people to gauge their effectiveness. In particular, leaders need employee feedback. Without it they have little hope of inspiring or motivating.
