"Free the power"
The guys at the top know stuff.
They know how the game is played and have the history of their experience to rely on.
The best leaders devolve power to make things happen because they also are aware there are always new ways to do what they have learned (usually at a fraction of the cost and in far less time).
It took 8 years to get from sub orbital flight to man on the moon and the team who did it had an average age of 26 (ref). They had no constraints of experience.
To emulate this, companies need to embrace the knowledge of all its staff.
Hewlett Packard and Microsoft are two companies which taps into the wisdom of the crowd by allowing internal blogs which enable ideas to flow between departments and up & down the hierarchy.
We've set up internal and private blogs to reproduce this and which is built on the understanding that a good idea is a good idea no matter where it comes from.
The people most at threat from this 'change' is middle management because they are the ones who are often the controllers of knowledge between the powers at the top of the company and workers at the coal face.
Challenge the system with the understanding new practices will arise and benefit the company as a whole.
This is the true value of social media internally and releasing power.
