New Microsoft (NASDAQ:MSFT) CEO Satya Nadella has been fast at work assembling his idea set to lieutenants as the software powerhouse prepares to challenge the likes of Apple and Google for a viable future in mobile.

After making a major move last month, Nadella is once again making waves with a series of sweeping management moves in Microsoft's C-Suite.

New faces, new places
Among the many recent moves, Nadella appointed the relatively new Mark Penn as Microsoft's new chief strategy officer, which should suit the former PR CEO and longtime political consultant. Beyond this, Nadella also added two new top marketing executives as the result of key departures at each of the respective posts.

These moves come in hopes of helping expedite Microsoft's increased fixation on getting more smartphones and tablets powered by Microsoft's mobile software into the hands of consumers under the Nadella regime. Although it's clear Micrsoft plans to lean heavily on low cost, emerging smartphones and tablets that have proven popular in some of mobile's fastest-growing regions, it's far from a given Microsoft will be able to realize this vision while maintaining today's robust profits.
