I was reading Tom Redman’s blog posting at the data roundtable about the customer-supplier model for data and thought it would be worth raising a particular question regarding an ongoing assumption about data use. Tom’s posting suggests that as individuals should cast themselves into a supplier or customer role. The suppliers should consider who the customers are and ask themselves whether they are meeting their customers’ needs. The customers should consider who the suppliers are and “act like customers.”
This model may work in a constrained environment where those roles can be ascertained. But that may be an assumption that is rapidly changing…
I was reading through one of Jim Harris’s blog entries about the his reinterpretation of Pascal’s wager in terms of data quality, and the posting made reference to an email he had received from Gordon Hamilton about the estimated costs of poor information quality. I noted Richard Ordowich’s comments from the Linkedin group were incorporated regarding the claims that 15-45% of the operating expense of virtually all organizations is WASTED due to data quality issues and thought I’d spend a little bit of time investigating the origins of some of these numbers.
So I thought it would be worth exploring the sources for some of the more popular claims about the costs of poor data quality.
