Overview of this book

Poor data quality can lead to increased costs, hinder revenue growth, compromise decision-making, and introduce risk into organizations. This leads to employees, customers, and suppliers finding every interaction with the organization frustrating. Practical Data Quality provides a comprehensive view of managing data quality within your organization, covering everything from business cases through to embedding improvements that you make to the organization permanently. Each chapter explains a key element of data quality management, from linking strategy and data together to profiling and designing business rules which reveal bad data. The book outlines a suite of tried-and-tested reports that highlight bad data and allow you to develop a plan to make corrections. Throughout the book, you’ll work with real-world examples and utilize re-usable templates to accelerate your initiatives. By the end of this book, you’ll have gained a clear understanding of every stage of a data quality initiative and be able to drive tangible results for your organization at pace.

Summary

In this chapter, we covered how to define useful data quality rules, with a tightly defined scope to avoid false positives. We also outlined all the key features of data quality rules in order to explain what information must be captured to document a useful data quality rule design.

We now understand the process that is required to design, develop, and test data quality rules and how good leadership can make a real difference in these technical phases of our work.

Now that we understand the end-to-end process of creating data quality rules, it is time to move on to how the results that these rules produce are presented to stakeholders.
