Here's an article on static code analyis that makes some nice points. I love the title: I’m not in denial, I’m in a hurry. It can be tough, at the end of a project, to find the time for that tidying up that you once thought there'd be time for. Better to get the comparison of what you're doing to best practices as you go along. In fact, every time you build your app. Then you'll know where you stand.
