How should a team review an indicator?

Table 4How should a team review an indicator?

Pattern in the review	First question	Do not conclude yet
A familiar label has one convenient field	Which facets of the target domain are actually observed?	The field is the construct
The metric is precise but has no validation path	What independent observation could challenge the reading?	Precision proves validity
The indicator rises after a workflow change	Did the process generate more target behavior or more recording?	The underlying construct improved
The field is edited after the outcome	Was the indicator available at the stated decision time?	The historical value was known ex ante
Missing records are coded as zero	Does absence mean non-occurrence, non-observation, or ineligibility?	Zero is the true value
The team assumes classical error	What evidence supports independence and the stated error distribution?	The reliability-ratio correction applies
A proxy is useful for triage	Is the narrower use and limitation written beside the score?	The proxy supports every downstream decision
A different construct has the same label	Did the target definition change between periods or teams?	The trend is comparable
