Turning service signals into valueA service signal is not always a complaint: it can be silence, or a healthy-looking average. A sensible fix can lift the symptom and still miss the outcome. Learn to size the signal, test what is behind it, and decide whether to press on or stop.Modules

Why the obvious fix is not always the whole answer. Know what the course asks you to do with a service signal, and where its two cases come from.

Define the issue behind the signal. Turn a service signal into an issue that is defined and sized, with its path to value shown.

Test what is behind it, then decide. Check an explanation in the way the issue calls for, read the result against the outcome that matters, and decide the next move.
