Human Computer Interaction (HCI) and Agile compatibility
Design in the Human Computer Interaction (HCI) world involves working with the user to understand the problem and come up with a user interface – typically on paper - of the entire system before turning it over, in Big Design Upfront (BDUF) manner, to the rest of the development team to build. So how can Robert Biddle claim that HCI has home-grown practices that are very similar to those of Agile?

User-Centric Development Approaches: What's Next?
On her Creating Passionate Users blog, Kathy Sierra recently envisioned software that's not just usable, but transparent, helping users achieve "flow" in their work without intrusive distractions, delays or constraints. Perhaps end-user "flow" is the next big differentiator - and if so, what will the development processes look like that support the creation of such software?
