A model grows rapidly after an identifier or free-text column is added. Compare model size and column cardinality before and after the addition and identify actual report usage.
Read article : Power BI: High-cardinality model columnsData Monitoring
A frequently refreshed model stores values that could be computed at query time. Inspect whether the calculation needs row-level storage or only responds to report filter context.
Read article : Power BI: Measure versus calculated columnData Monitoring
A total differs from the sum of the rows displayed in a visual. Evaluate the measure under row and total filter contexts and identify whether it is additive.

Revenue appears twice after combining two fact-like tables. Inspect relationship cardinality and compare distinct business keys at the intended grain.
Read article : Power BI: Many-to-many relationship inflationData Monitoring
Selecting one category changes an unrelated KPI. Trace relationship filter directions and compare the affected measure with a simpler single-direction model.

A conversion KPI changes when the same data is regrouped. Calculate total conversions divided by total visits and compare it with an unweighted average of per-row rates.
Read article : Power BI: Ratio of sums versus average of ratiosData Monitoring
No data is shown as a healthy zero-error rate. Inspect the denominator and distinguish missing observations from a measured count of zero.
