Nine Dimensions of Information Quality
-
Conformed: Does it conform to the data standards (i.e. MM/DD/YYY for date or ###-##-#### for Social Security Number)
-
Valid: Beyond Conformance, does the information make sense. For example: year in a date is within the expected range (2103 vs 2013) or no dummy values such as 999-99-9999 for SSN.
-
Complete: No missing values
-
Accurate: Requires an authoritative source to compare against. Sometimes called “correct.”
-
Consistent: is the information the same between systems/applications
-
Unique: If expected, is the information unique within the data set
-
Available: Is the information accessible and/or was the application running during business hours or according to Service Level Agreements
-
Timely: Was the information entered into the system or application in a manner that complied with turnaround times or SLAs
-
Current: How likely is the information to represent “Now”
