Your question is Leading Signals of Operational Failure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are managing a product or engineering team and want earlier warning signs than customer impact or missed business goals. The team already looks at outcome metrics, but those usually move after the underlying operating issues have been building for a while.
What leading indicators would you watch to know a team is heading toward an operational failure before it shows up in results?
