“Once you have eliminated the impossible, whatever remains, however improbable, must be the truth..” — Spock, Star Trek: The Original Series
This is not the only place i have run into this quote but we are still on a Quality Assurance and Metrics theme for a little while longer and metrics are a great way of eliminating the impossible from many situations. Measurements can be gamed, they can be misinterpreted but they do not lie in and of themselves. If they are simple and transparent to the user, then we can make use of them to ensure that the recommended path to Quality Improvement is the correct one.
Concentrate on the truth.
