There's always a huge spectrum. There people @#$##$ in the market, there are people that think they know what they're doing and they don't. There's banks betting that people will earn more, spend less, repay loans, there's banks taking advantage of people, there's people speculating and betting. Why are casinos making money? People like to bet. We all do, we just do it in different ways. conservative people place conservative bets, but they bet all the same. And they are conservative in some areas, risky in others.

Since 1998, I've worked for 4 companies, and that's a lot in my mind. I've seen things done a lot of ways. In the IT world, there are people that want to get every last spec done and there are people that hear "i want" and start coding. Neither of them is wrong if you can make it work.

Personally I go for an agile approach, with developers pairing with business people, not other developers, to do a little work, test it, let someone use it and give feedback and then evolve it.
