Last week Per Kroll and myself did a live online chat regarding agile software development at scale. One of the topics that was brought up was whether or not you can be agile with the RUP. The answer was a definite yes. I first wrote about how to be agile with RUP in my Agile Modeling book (www.ambysoft.com/books/agileModeling.html) and over the years have expanded upon those ideas. Craig Larman, Per Kroll, Bruce MacIsaac, Ivar Jacobson, and many others have also written about how to be agile with RUP.
Anyway, the transcript of the entire chat can be found at http://download.boulder.ibm.com/ibmdl/pub/software/dw/rational/chat/ambler-kroll_transcript.txt for anyone interested.
I just thought that this might be an interesting topic to discuss.
