This collaboration keynote by Charles Leadbeater discusses that most ideas are a result of sharing and teamwork over a number of years. He brings up the philosophy that people have ingredients to the formula of an innovation. Because of this, it is rewarding when individuals feel needed in the way that they are a key to solving a problem.
The side effect of this, however, is that one person's risk becomes that of the entire group. From this, you will find yourself relying on people and lacking control in certain situations. As established in this collaboration keynote, the ability to work together has increased significantly because of the web and this will lead to many more innovations from different collaborations worldwide.
