Very good and long article by Cennydd Bowles on the relation between design and agile development.
“For many designers, Agile is already a fact of life (and for those less accustomed, some recommended reading follows at the foot of this article). We are reaching the point where we must either acclimatize or risk being bypassed. The good news is that Agile does allow us to still do the things we hold dear—research, develop a vision, and test and improve our designs—we just need new techniques. Now is the time to get real, and prove design can adapt, if we want to stay relevant in these increasingly unreal times.”
