Marketing starts from inside first and that is going to be mantra for Microsoft when its will be ready with its new Windows Phone 7 device. Before any estimation and sales plan of windows Phone 7, we are hearing about Free Windows Phone 7 device distribution to all Microsoft’s 90,000 employees, much before it will go on self at various retail outlet worldwide.

Despite of having significant impact on company’s expenses book, it’s a move which will surely help Microsoft to release a complete bug free phone unlike iPhone 4.0 which recently went through lots of criticism due to few performance issues. No other idea can be better but to allow own employees to test the phone in real working conditions and report any issue, which can be fixed internally with much cry.

I am sure Microsoft will ensure that hat edge isn’t bleeding too heavily, because not even their own employees will want to use a buggy device. However, from what we’ve heard about Windows Phone 7 lately, it’s definitely usable.

Recent announcement has already created much more excitement among all employees ( like tweets above ) and if you are working in Microsoft and this sounds absolutely fresh to you, you can read the internal email from Microsoft Andy Lees which explains that the “process will vary based on your market, your carrier, and your launch date” and promises “more information closer to launch.”

Now it would be interesting to see how far Microsoft succeed with its bug free release attempt where their own employees will be working as testers.
