The reverse is also true though -- hearing from folks that we need to measure nothing because "trust me". Both lead to poor outcomes, ime.

A good engineering team has measurements in place that are reasonable approximations, where it is reasonable to build them, but also treats them as prompts rather than absolutes. Asking "why is this metric out of band?" is infinitely more valuable than stating "this metric is out of band, we've failed".

Out of band means communicated on different channels than ordinary information. For example a metric communicated out of band would be told to you in person instead of showing up on your universal agent smith react widget dashboard. :-)

Two different jargon phrases overlapping here, as I’m sure you know. Yours is “out of communication band” whereas GP is “out of predictive band.” Yours is a bit more common to me, but I hear both.
