The document discusses data quality challenges, especially with big data. It notes that data quality starts at data creation and production, and that both data producers and consumers play a role. With big data, quality issues like redundancy, lack of resolution, and noise are exacerbated due to diverse sources of data, lack of documentation and standards, and increasing volumes of data. The document recommends treating data as a product and implementing quality standards, detection of problems, and root cause analysis to improve quality rather than just collecting more raw data. A shared responsibility approach between business and IT is needed to develop a common understanding of data.
