Blog: Very Short Blog Posts (14): “It works!”

“It works” is one of Jerry Weinberg‘s nominees for the most ambiguous sentence in the English language.

To me, when people say “it works”, they really mean

Some aspect
of some feature
or some function
appeared
to meet some requirement
to some degree
based on some theory
and based on some observation
that some agent made
under some conditions
once
or maybe more.

One of the most important tasks for a tester is to question the statement “it works”, to investigate the claim, and to elaborate on it such that important people in the product know what it really means.
