Recently, Freeform Dynamics looked at data quality from the perspective of IT professionals and of line of business managers.
Reasons for why data quality degrades over time include typing mistakes when editing records, software bugs or communications glitches introducing errors, unverified external data sources being used to update or supplement information, as well as data records not being updated at all due to pressure of work or simple oversight.
Perhaps more importantly, poor data quality can lead to organisations taking decisions based on inaccurate or out-of-date information, potentially with expensive consequences.The starting point for improving data quality and integrity is deciding just what data source, or sources, should be regarded as holding the "truth" when considering any data record.
