I want to challenge that way of thinking. Yes, you cannot write a roadmap that states, do this then this and you will become CEO. However, leading companies are clearly defining goals and initiatives, laying out future opportunities and engaging their workforce in meaningful conversations about their career. They are doing it in a proactive way. Instead of using conventional approaches like annual reviews to discuss career path and employee satisfaction, these leading companies will use every opportunity to engage with their employees. See "One Minute Manager" by Ken Blanchard for simple and effective methods to engage your workforce.
