 This video "History of MOS 6502" gets into some of it:


In the video, the numbers used are a previous 70% failure rate with 
Motorola to a 30% failure rate with MOS.

If you believe these numbers, it would seem to be almost entirely 
manufacturing improvements that made the 6502 so successful from a 
business point of view at first.  The high volume low cost that followed 
would have well served to amplify that success, of course.
