I've known a few great starters, a few great finishers and a lot of neithers. The starters could rapidly invent brilliant tech and get it to a prototype phase that looks beautiful on the surface, but is unshippable under the hood. When it came time to clean, polish and fill out all the annoying details, the starters got bored and distracted. They either slowed to a crawl or convinced themselves that some new invention is necessary to ship what they are supposed to be finishing. Good finishers are actually more rare than good starters in my experience. The finishers I've known are terriblely uncomfortable at the start. Everything is too vague and open ended. They weren't terribly imaginative or inventive. But, when it came time to ship they got in gear. Here's the burn-down list. Fill in the details. Check the schedule. Get it wrapped up, put a bow on it and shove it out the door!
