    The more interesting question is: Is GrayR familiar with any of the discussions that followed Kano’s model (developed 50 years ago and never tested it empirically … which is therefore also known as a “heuristic model” :-)?
    And what strange logic to equate “expected quality” with “x lbs of material” … So now we shift “expectations” to the level of “quantity” in order to safe the assumption of that all customers have “expectations”. … “I think all customers have some basic expectations” that’s a very personal thought, commendable, but just that: a personal thought, i.e. an assumption :-).
