Is agile considered a product development framework or just a software development methodology? I think that's quite a difficult question to answer. I'm sure anyone that has worked on product development finds it difficult to figure out how things like research, design and maybe even quality assurance should fit into the agile way of doing things.

Agile is so flexible that it doesn't really answer the question of how some of the non-software dev things fit in, ultimately it comes down to strong leadership, and the honesty to say when something is going wrong. At the very least, agile provides the opportunity to fix bad decisions.
