I like maccard’s response better than mine: > measuring two developers and saying one is 10x more productive than the other doesn't mean that the first is 10x better, just that they are 10x better at what you are measuring under the terms you are measuring. If you’re interpreting the author’s statement as an assessment of full potential, then you may be right. I didn’t read it that way, and honestly I don’t think that assessment can be easily made.
