“Insufficient facts always invite danger.” — Spock, Star Trek: The Original Series
I am not the Star Trek expert in our house so cannot give the Episode and Season from which this came but i suspect that some experts could.
However, this is an excellent quote for our current blog (see link below) series on Measurements and Metrics. Many people have impressions about how well processes or products are working (sometimes referred to as the Smell Test) but these do not work as well as statistics. An objective measurement provides irrefutable evidence of how things are working.
Insufficient facts are dangerous. Having the facts always helps.
