Charlie Kindel (Charlie Kindel), coordinator of the group developing Windows Phone, reported on how the principles will be the development of the new OS. In particular, he wrote that to "fix the energy, ability and attention of developers and manufacturers to the platform and ecosystem for the cross-cutting principle.
Among other principles, the development of the following theses:
"Every decision we have taken should take into account what impact it will have on end users.
We will do a little, but very high quality. It is better not to do some sort of functionality than to implement it badly. There are always new versions.
The creation or documentation of the API without a clear understanding of how it will be used. API, created by the principle of "do, and then we shall see," almost always futile, and unnecessarily burden the system.
We will build on the shoulders of giants. Wherever possible, it is better to integrate than to build.
We will try not to show our organizational boundaries developers.
Some results of these approaches can be seen now, such as the integration of Windows Phone 7 with Xbox, Zune and Microsoft LIVE. The principle of "do not create the functionality of poor quality" has already manifested itself in the fact that there WP7 some functions that are in WM6, such as multitasking and advanced file system.
