Idea No. 2: Competition
They say competition breeds excellence. Probably true. The entire premise of our capitalistic economy is based on that. Competition drives us to dig deeper for our eternal search for enhancing our productivity. Competition brings about the inner mojo in us to strive to attain the "un-obvious" and to think harder than the next guy, to strive harder to close the deal. I know from personal experience that competition makes me think about everything I do and try harder and smarter; it's a drive that comes from deep inside. It pumps adrenalin into my veins when I look at my competitors (and endorphin when I succeed).
Competition can be at times destructive-if we make winning the sole focus of an exercise and allow for noneffective rules and shortcuts. History has taught us that intensely competitive environments attract people who will take shortcuts. This is a fact of the moral fiber of our species. Accept it, acknowledge it and deal with it. However the cumulative effects of competition have been thoroughly proven to increase overall effectiveness. See capitalism versus socialism.
The challenge we face is to bring about a system of competition of ideas and engagement within our employee base and peers that is not destructive. Having clear rules of the road is a great start to making sure that mass-employee collaboration initiatives do not spiral out of hand. Having an equal focus on collaboration as much as on winning also tempers our innate need for being number one-you can win in multiple ways. As an organization, you are not necessarily looking for a needle in a haystack; you are building a better barn.
