MICROSOFT announced a big internal re-organisation last week, drastically slimming down the number of sub-divisions and teams within it. CEO Steve Ballmer said it was a "far-reaching realignment of the company" and gave it a name: One Microsoft. The aim is to act faster, to respond to a rapidly changing market better, to work together as a single (very large) team. Cynics, of course, might say it was also to regain ground lost to Apple in recent years. You can read Ballmer's memo to staff at www.tinyurl.com/ballmer-memo.
