Incrementalism, which I define as "doing a little more to get a little more," can be a bane or a boost. When we seek the next higher step, the somewhat better design, or the higher success rate, we are betting that the benefits of the increment are worth any costs and delays.
In part, it is our simmering dissatisfaction with the status quo that makes us try to improve--as people, as companies, and as a nation. Money and material goods can be manipulated. Time is our only fixed resource; it can't be stored, stretched, or condensed. So when we waste one unit of time trying for an incrementally better solution, we have spent something we cannot recover.
The way to beat the clock is to use each increment to learn. Learning makes the next decision smarter, and hopefully, better.
We may even learn that what we already have is pretty good.
