Don't build the moon, build the path to reach it. The failure rate of building huge projects is always very high. Small projects and small teams are always likely to succeed. Quick meetings, quick decisions and grabable goals are the essence of success. So, how do you build a huge bridge? You don't build bricks and steel you buy them and assemble to build it. You create components with straight forward scope and simple interfaces and then hook them together to perform. Growth is good when its either straight vertical or plain horizontal. Slanted buildings are doomed to collapse.
