Anders NorÃ¥s has a blog entry where he shows how one can easily apply the wrong solution to a problem. It’s from a book, so of course the authors set out to show one specific thing, but it could be a real world scenario too. People tend to fall in love with one way to do stuff, and try to apply that to everything. On the way he shows some good OO design that should be the first thing that springs to mind. Check out his entry here.
Also check out the link he supplies to Primitive Obsession. I knew it was wrong, I just didn’t have a name for it. Sweet. 🙂
And while you’re at it check out his post on software factories. It is a thorough explanation of how building frameworks is the right way to go instead of doing code generation.
