There’s an old IT adage that is pretty much applicable to any endeavor:
For any project, you can have it fast, accurate, or cheap. Choose two. In far too many cases, management/owners wants all three, and that just doesn’t work. If you want fast and accurate, it won’t be cheap. If you want fast and cheap, the results probably won’t be accurate. Etc. Wanting all three is a perpetual “do more with less”.
Someone on Slashdot posted a great reply: “When you choose all three you can’t say with any certainty which you’ll actually get when all is said and done – if indeed you get any of them at all.”
Another phrase that comes to mind is the “We the unwilling, led by the unknowing, have done so much with so little for so long that we are now qualified to do anything with nothing.”
