Once we set your strategy and are clear about goals and objectives, everything else is about execution. Solid research shows that excellent execution of a mediocre strategy beats poor execution of the best strategy.
Once you internalize that concept, look at where execution takes place. It's in the middle. It's the middle management that is actually driving a lot of the productivity and work that is delivered in organizations. They are closer to the people and the work than senior management, who is typically focused on developing the strategy. It's the middle managers that are translating the strategy into an executable plan and as well as communicating those plan to the workers.
Whether you looking at developing and coaching leaders in your organization or trying to determine who to invest in, your new target should be the middle, not just your top 10%. Your top 10% is already doing great. They need recognition and rewards, and of course it would be great if they could be even better through development opportunities. Why is that the middle, that is the people right below them down to those in the 50% percentile, don't get as much or any development support or leadership coaching? They are often subjected to training classes the majority don't really need and expected to work harder and do better. What would happen if you actually invest in them? Have you calculated the increase in value of your company if your people would execute 30% better?
Not every one is born a rock star, but certainly there are many who, with some extra help, can become stellar. According to Thomas Colligan, vice dean of Wharton, there is the 60/20/20 rule. "When people come in the door [to a law firm or investment bank], 20% will make partner no matter what you do; 20% will not make partner no matter what you do, and 60% will make partner if you do the right things." What are the implications of this? No matter what, you will always have people who are the top and will naturally succeed because of their inherent gifts, those at the bottom who will not succeed, and more importantly those in the middle who if they try hard enough and had the right help would succeed.
