This is a pretty good book for aiding in making business decisions. It presents a methodology for measuring advantages and inconveniences and analyzing data. I have not read other management style books on this particular topic, so I don't know how it measures up. I just know that for me, it was relevant and helpful.
Great book! Had the beginning on how we as humans make decisions and why we make the choices and estimates we do. Good intro to Monte Carlo simulation and parametric estimating. I find that it has really opened my perception towards decision making.
