The company is considering building mobile hardware as a back up, in the event that its current approach of providing software to handset makers such as Nokia and HTC falters, said the people, who requested anonymity because the plans are private. Microsoft is for now confident that its current strategy will succeed, the people said.
Chief Executive Officer Steve Ballmer introduced the latest version of Windows Phone software, available on devices such as Nokia's Lumia 920 and the HTC 8X, to help his company win back share lost to competitors such as Apple. Microsoft has already demonstrated a willingness to build hardware, even if it means competing with long-time partners, through the creation of Surface, a tablet that runs Windows software.
"We are big believers in our hardware partners and together we're focused on bringing Windows Phone 8 to market with them," Redmond, Washington-based Microsoft said in an emailed statement.
Microsoft, the world's largest software maker, embarked on the Surface strategy on concern that its existing partners, which include Hewlett-Packard and Dell, hadn't been able to devise their own hardware capable of going head-to-head against the iPad, according to the people with knowledge of the strategy. Microsoft's Windows Phone group doesn't currently have comparable concerns regarding handsets, the people said.
Still, Microsoft wants to ensure that if the handset makers come up short, the company won't have to start building its own hardware from scratch and on short notice, one of the people said.
Doug Dawson, a spokesman for Espoo, Finland-based Nokia, declined to comment, as did Kent Hollenbeck, a spokesman for Taoyuan City, Taiwan-based HTC.
Ballmer highlighted the prospect of Microsoft building more hardware in his annual letter to shareholders last month.
"This is a significant shift, both in what we do and how we see ourselves - as a devices and services company," Ballmer said in the letter. In interviews, Ballmer has declined to rule out making a phone.
At the same time, the CEO is pleased with the work with the handset makers have done, in particular HTC, people familiar with his thinking said. When Ballmer showed a video of what's on his personal Windows Phone 8 handset this week, the phone he showed as his own was the new HTC model.
The Wall Street Journal previously reported that Microsoft's component-maker partners in Asia are already testing parts for a Microsoft phone.
