Too much money might be part of Blue Origin's problem to deliver. SpaceX did not have the luxury to take ages, they had to build a working rocket to be able make money or die otherwise.

I can only recommend Eric Berger's excellent book "Liftoff" to gain insights into SpaceX' way of working to get the Falcon 1 rocket off the ground and eventually into orbit. I cannot imagine Blue Origin having operated in a similar way at any point in their history.
