"You cannot manage what you cannot measure" - Peter Drucker
Most of us have heard this quote many times, though it’s probably more relevant to software development to say:
“You cannot manage what you do not measure”.
As software developers, we can figure out how to measure lots of stuff, and we can automate that measurement. We can even design in alerts to send us email when the measurements go out of bounds, or fail. But when we start getting lots of these alerts, and know that some of them are test issues rather than product issues, we often don’t pay close attention to them.
