Data quality matters
Conclusion: Operational data is the heart of a business in the information age. Without operational data the organisation would cease to function, irrespective of the software and hardware infrastructure that is in place. Hence the quality of data is a logical starting point for identifying opportunities to improve business operations. When used in combination with top-down value chain analysis, a quality assessment and categorisation of data can be used to identify essential system functionality, to identify pockets of obsolete functionality, and to discover sets of unreliable or redundant data.
