My recent blog post "The Data Quality Wager" received a provocative comment from Richard Ordowich that sparked another round of discussion and debate about proactive data quality versus reactive data quality in the LinkedIn Group for the IAIDQ.

“Data quality is a reactive practice,” explained Ordowich. “Perhaps that is not what is professed in the musings of others or the desired outcome, but it is nevertheless the current state of the best practices. Data profiling and data cleansing are after the fact data quality practices. The data is already defective.  Proactive defect prevention requires a greater discipline and changes to organizational behavior that is not part of the current best practices. This I suggest is wishful thinking at this point in time.”
