Data Quality's Three Tests
Captions available
The idea
Data quality decomposes into accuracy, completeness, and consistency — three separately checkable properties, each able to fail while the others hold.
In practice
A patient record can be accurate yet incomplete, or complete yet quietly self-contradicting.
Where people slip
One passing test proves one property, never all three.
