Bruce Eckel - The Mythical 5%:

"Usually the things that make or break a project are process and people issues. The way that you work on a day-to-day basis. Who your architects are, who your managers are, and who you are working with on the programming team. How you communicate, and most importantly how you solve process and people problems when they come up. The fastest way to get stuck is to think that it's all about the technology and to believe that you can ram your way through the other things. Those other things are the most likely ones to stop you cold.

In my first jobs, I saw lots of managers making stupid decisions, and so, logically, I came to the conclusion that managers and management was stupid. It's a commonly held belief in our profession: if you're not smart enough to deal with the technology, you go into management. Over time I very slowly learned that the task of management wasn't stupid, it's just very, very hard. That's why all those stupid decisions are still being made; management is much harder than technology because it involves virtually no deterministic factors. It's all guesswork, so if you don't have good intuition you'll probably make stupid decisions.

[...] There's one more very important maxim from Gerald Weinberg which doesn't really answer anything as much as gives you a way to understand what happens. He says: "Things are the way they are because they got that way ... one logical step at a time." It's the legendary frog in the saucepan. So from your fresh new perspective things might look ridiculous, but remember that each decision on the way was made by someone weighing the issues and making what seemed like the best choice at the time. This viewpoint doesn't solve the problem but it can make you more compassionate about the people who are stuck there."
