The way Mac window management works, ironically, is that you manage windows as little as possible. You don't even go as far as to maximize or tile most of them. Instead, windows are sized to fit their content and sit where they may, overlapping each other and allowing the most relevant portions of each to peek through, like the digital analogue of a desk with a pile of odd-sized papers. Windows are foregrounded by either clicking a bit that's peeking out or triggering Exposé and choosing a thumbnail.

It's a very different mindset than that of a Windows-like desktop or tiling window manager.
