Abstract:

Impacts of poor quality of information are felt at every level in an organisation. To mitigate these impacts, information quality must be assessed and managed. However, obtaining accurate measurements and cost-effective assessments of information quality have proven to be an extremely difficult task due to the complexities of information systems and the various information quality dimensions depending upon the business properties. Most of the available information quality assessment frameworks are based on measuring customer data only and thus, they do not provide comprehensive and systematic assessment of information quality. However, not only that these approaches are unable to provide a complete measurement of all the information quality dimensions, but are also unable to highlight the dirtiness of data due to the correlation of various information quality dimensions. This paper introduces a new approach to information quality measurement and employs Six Sigma approach to information quality assessment. This approach focuses on continuous improvement of information quality by a systematic assessment of multiple information quality dimensions. It specifically tackles the correlation and the relative importance of information quality dimensions and proposes precise and systematic information quality assessment criteria.
