This is really good article, probably one of the best I've seen come out of Mashable. The exercise of determining what are the clichés of any industry seems something you'd want to tackle with a group - maybe a good geek-out exercise for entrepreneur meetups?
The book by the article's author (Disrupt) is quite good too. It takes he points in the article and expands on them, giving you concrete exercises to work through to generate new ideas. While I don't think you can systematize innovation, I do think there are certain things you can do to come up with interesting business ideas.
If you're like me and find developing applications easy but have a very hard time deciding what to create, I'd recommend reading Disrupt.
