From the post: "recorded exactly one bug
against their system" I guess it depends on
what the definition of "record a bug"
is. Sometimes someone can writeup a "user
story" to change the desired behavior. Thus, no
bug.
I'm not knocking the quality aspect of XP, but there are
no industry standard definitions of bugs. And
recategorizing things to make them not bugs is common.
For an analogy with retailers and ordering metrics,
there are actual *standards* that define what a
"perfect order" is. You meet all the
requirements for a perfect order, and you can count it.
Otherwise, you can't. Period.
Darrell: sure, I was just using this "1 per
year" as an extreme example. Obviously the
world isn't *that* wonderful, but Fowler lists some more
realistic stuff in there too. I still love those
numbers.
