Common Data Quality IssuesData Quality Issue Sample Data Problem

Format Do values follow consistent formatting standards ?

Telephone number formats:xxxxxxxxxx, (xxx) xxx-xxxx 1.xxx.xxx.xxxx, etc.

Standard Are data elements consistently defined and understood ? ‘Gender code’ = M, F, U

‘Gender code’ = 0, 1, 2

Consistent Do values represent the same meaning ? How is revenue presented ?Dollars, Euro, Both?

Complete Is all necessary data present ? 20% of customers’ last name is blank, 50% of zip-codes are 99999

Accurate Does the data accurately represent reality or a verifiable source?

A Supplier is listed as ‘Active’ but went out of business six years ago

Valid Do data values fall within acceptable ranges?

Salary values should be between 60,000-120,000

Duplicates Data appears several times Both John Ryan and Jack Ryan appear in the system – are they the same person?
