Measuring
the Value of Usability Engineering
Practitioners
in the field of usability engineering refer to the demonstration of the
value of usability engineering as the "Holy Grail" of the field. Such
an allusion implies that this proof is something that may or may not exist,
but that would be the treasure of a lifetime. If proof of the value of
usability is so desirable, why don't usability engineers spend more time
measuring it? Here are seven reasons I have observed why usability engineers
don't measure the value of usability efforts, rebuttals to each argument,
and suggestions for how to remedy them. At the conclusion of this discussion,
I will identify and examine a commonality among the reasons that may be
the single most problematic barrier to the measurement of the value of
usability.
