Shortly after Ray Ozzie joined Microsoft, becoming its chief architect, he wrote a company-wide memo warning that Microsoft had to shed its complacency and recognize the danger posed by competitors like Google and thousands of startups more attuned to the the effective use of Internet technologies. "It's clear that if we fail to do so, our business as we know it is at risk," he wrote. "We must respond quickly and decisively."
Ozzie left Microsoft in 2010, having steered it toward a greater recognition of the importance of cloud computing, but the fact that Microsoft had to acquire Yammer rather than creating the technology on its own raises the question of whether the message sunk in. Or maybe it did, and this acquisition is one of the quick and decisive actions Microsoft is taking to catch up.
