Windows Phone 7 development principles revealed


24, 2010

windowsphoneCharlie Kindel, Partner Group Program Manager for the Windows Phone Application Platform & Developer Experience, wrote an article explaining the design approach for Windows Phone 7 series.

He notes the their purpose was:

.. to harness the energy, talent, and attention of developers and designers with a platform and ecosystem that delivers on the developer experience end to end; that, combined with the phone’s end-user experience, results in a winning virtuous cycle.

To implement this long-term vision some of their development principles were:

  • Every decision we make must be made mindful of the effect on end-users.
  • We will do a few things and do them very, very well; we are better off not having a capability than doing it poorly. There are always future versions.
  • No API will be created or documented without a clear use case; “build it and they will come” APIs almost always do nothing but create bad legacy.
  • We will build on the shoulders of giants; where possible integrate instead of create.
  • We will strive to not show our organizational boundaries to developers.

We can see clear evidence of the principles in action in terms of the integration Windows Phone 7 brings between Xbox, Zune and Microsoft’s Live services. However we also see the downside of reduced functionality in initial releases. “We are better off not having a capability” may result in Windows Phone 7 having many less features than Windows Mobile 6.x had, no matter how poorly implemented.
