I frequently monitor the price of my books on Amazon and noticed that this afternoon the Practitioner’s Guide to Data Quality Improvement was selling for $33.45, which is a discount of 44%. If you have been waiting to buy the book, now isĀ  a good time. This is the lowest price I have seen so far.

Here are some aspects I have tried to cover in the book:

  • The ability to build a business case for instituting a data quality program;
  • Assessing levels of data quality maturity;
  • The guidelines and techniques for evaluating data quality and identifying metrics related to the achievement of business objectives;
  • The techniques for measuring, reporting, and taking action based on these metrics; and
  • The policies and processes used in exploiting data quality tools and technologies for data quality improvement
