Cash and the Law of Diminishing Returns

Cash and the Law of Diminishing Returns?????One of my favorite economic laws is the Law of Diminishing Returns. It's basic stuff at first glance, but can really haunt a project manager if he's not careful. I know you're familiar with the Law of Diminishing Returns, but that guy from Sheboygan is also reading, so let me help him out.?????Imagine that you have a wheat field. Wait, he's from Sheboygan. Imagine that you have a MBT Lami Shoes corn field and you know that you can get 100 trucks of corn out of the field. That's the most corn you'll ever get from the field. You also know that if you hire 10 guys to harvest the corn for you, they'll be done in 2 days. So you reason that if you hire 20 guys you'll be done in 1 day. So this must mean that if you hire 40 workers, all the corn will be harvested in half a day, right? Maybe, but if you continue to add workers to the field, a few things will happen:

Your yield—100 trucks of corn—remains the same no matter how quickly you harvest the corn.
Your profit will decline because you have to pay all those workers to harvest the corn for you. At some point, you may even be upside down on MBT Chapa GTX,profitability because of the expense of labor.
The workers will become counterproductive because they'll start getting into each other's way.
?????So how does all this corn relate to an IT project?
