I also prefer the PF method but mainly was wondering why there was a change from the original document they produced in the early 80s where they recommended the PM make the selection. That document was considered a benchmark from what I can tell given all the references to it in various human factors studies over the years.
However, in the last decade studies have gone back to favoring the PF method. Just wondering why. Thanks!
