Apple's Development Process?

Hi,

Does anyone know any specifics about Apple's development process?  How
agile they are, what CM do they use, what are their documentation
practices, etc.  I recently read a great little book, "Inside Apple: How
America's Most Admired--and Secretive--Company Really Works", but it left
me with more questions than answers.  Googling did not yield anything
worthile.

I'd also be interesting in a non-BS answer as to why so many important
Microsoft employees have left in the past few months, even the originator
of this list, Chris Sells!  It seems as though a dark cloud has settled
over Redmond, but I can't put my finger on what it is.

Thanks,
Mike
