Research on Combining Agile with Waterfall

An issue facing many agile teams is how they can coexist with non-agile teams within the same company and often working on the same project. A friend, Eva Gysling, is doing some academic research into this topic. She's prepared an 11-topic free-form questionnaire soliciting experiences and thoughts on mixing agile with waterfall.

If you have experience with this, please help her out by downloading the questionnaire and sending your responses to her at the address in the questionnaire. Given the rampancy of this situation, I think this can be very important research.

Thanks for helping.
