Q&A on the Book Evidence-Based Management

The most important issue in organizational data quality is whether you have the data you need to test whether your beliefs about the organization are really true. So if I believe my organization has a reliable backoffice in terms of transactions, do I have the data that show how many errors are made a day or a month for a given volume of transactions.? Counts tell us almost nothing; we need rates, like errors/daily volume. If I am relying on my impressions, I am talking to myself.
