How complete is your data? August 15, 2007

Data completeness is contingent upon first knowing the target population* relative to the number of missing data elements (bad values) to good values by data element. 

Consider analyzing over time and set up on a scheduled basis missing value reports (better yet aggregate datasets) to study over time data completeness patterns.  These findings might also reveal other data governance processes, policies, and standards in your organization for consideration.

It is advised to include a statistical analyst early on in outlining this process in order to help define data completeness specific to your organization – past, present, and future.

*target population could be anything from your customer name/address customer master database to product-specific datasets and all their associated attributes.
