Poor data quality is like dirt on the windshield. You may be able to drive for a long time with slowly degrading vision, but at some point, you either have to stop and clear the windshield or risk everything.

For the next several years, corporate buyers will be bent on reining in IT budgets; they'll look for technologies that address business problems directly, provide a near-term return on investment, and improve customer acquisition and retention, cost cutting, revenue, or profits. The word from the top is clear: Make this stuff work. [1]

There's an expectation that it's time to get a return on these investments. The way to do that is to increase the quality of the data so that you can analyze who your customers are and think more strategically. [2]

Quoted in link_outThe High Cost of Dirty Data, February 2002


Fully 75% of respondents reported significant problems as a result of defective data. ...

Ask anyone who has built a data warehouse or who is responsible for managing one, and they'll tell you that ensuring data integrity and cleanliness is the most difficult step in the overall warehouse project. By far the largest 'unexpected' labor cost in data warehousing involves data cleanup and its associated data loading processes. In fact, organizations often report that as much as 70% of their effort went into supporting the data cleansing and transformation process.

Data warehouses follow the "garbage in = garbage out" (GIGO) equation very closely. In fact, the millions of dollars spent designing, building, and implementing will be wasted without good data quality.

Reason #1 [for the failure of CRM projects]: Data is ignored. ... Enterprises must have a detailed understanding of the quality of their data — how to clean it up, how to keep it clean, where to source it, and what third-party data is required. ... Action Item: Have a data quality strategy. Devote one-half of the total timeline of the CRM project to data elements.

Bombarding your business trading partners (both customers and suppliers) with poor data will be harder to sustain than bombarding one's own management and knowledge workers with poor data. Trading partners will quickly go to another partner.
