IT development and Millennials

Millennials are said to be redefining software application development ("The Move to Mashups: How the Millennials are Redefining Software Development", Knowledge@W.P. Carey, May 7, 2008). Old style IT development was a long, slow process creating enormous, multi-functional systems and a backlog of simple applications. Mash-ups are said to characterize the newer model for IT development - the long tail of IT development where simple applications are created quickly, collaboratively and as needed.
