Under the new structure, Microsoft, which employs nearly 100,000 people, will distribute activities across four divisions -- half as many as now. Given the size and scale of Microsoft's operations, it was no doubt a huge undertaking to realign the company's talents to fit its evolving goals. Nevertheless, renaming divisions and shuffling executives will likely seem simple compared to what comes next -- making the new strategy pay off.
Observers on Wall Street and throughout the IT world will be watching closely for signs of progress. Microsoft's stock price has been on the rise in recent months, propelled by strong earnings in the face of the PC market's worst downturn in history. Even so, CEO Steve Ballmer remains under pressure, as the meteoric progress of cloud-oriented businesses such as Windows Azure and Office 365 has not distracted from Windows 8's mixed reception and poor progress.
The full effect of the reorg won't play out for months, but Ballmer will face a stiff test over the next nine months; the company hopes that Windows 8.1 will jumpstart device sales over the holidays and tempt enterprise users as businesses move off of Windows XP, which remains popular but will lose support in April.

Julie Larson-Green, who had overseen Windows, will lead a new devices and studio group whose purview will include Xbox hardware, the Surface line of tablets, hardware accessories and games.
Operating systems, including the Xbox, will be consolidated under Terry Myerson, who previously oversaw engineering for Windows Phone.
Qi Lu, who had led Bing, will take over a new applications group and manage the company's Office and Skype businesses
Satya Nadella, who had been running Windows Azure, will head a new cloud and enterprise group.
Aside from the four divisions noted above, Ballmer has also expanded the role of Tony Bates, the former president of Skype. He will lead mergers and acquisitions, business development and relations with developers. Kurt DelBene, who ran the Office division, is retiring.
Some product groups will continue to operate relatively unchanged at the local level, but with new managers and cross-divisional cooperation added to the mix. Kirill Tatarinov will continue to run Microsoft Dynamics, for example, but will report to Qi Lu for product development, Tami Reller for marketing, and to the COO group, which will continue to be led by Kevin Turner, for sales.
"As the times change, so must our company," Ballmer wrote in a memo to employees that introduced the changes. Rumors of the shakeup had grown louder in recent weeks. The CEO reportedly confined reorg planning to a small group of close associates, a decision that allegedly left some excluded execs uncertain about their futures.
The anxiety of Microsoft employees aside, the new organizational hierarchy appears well-positioned to address at least some of the old system's flaws.
