In baseball, you have Starters and Closers.
Starters get the game going and if their good, generate a lead big enough so that anyone can close.
Closers finish up what the Starter began. The really good ones, take a potential failure from a Starter and turn it around into a win.
You can have good Starters (they get the projects going, establish the architecture, get things up and running) and you can have good closers (they save the day on production issues, adjust designs when problems go astray and generally make them a success).
Or you can me in that elusive group, where you are the Starter and the Closer, knocking it out of the park 7 days a week.
