Practical Data Quality

By: Robert Hawker

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.

This section describes how this can be approached.

Roadmap of data quality initiatives

A single data quality initiative (as described in Chapters 3 to 8) will include a range of different people – from project managers to data quality rule developers. These initiative-based resources will typically leave the organization or return to their original roles when the initiative ends. If there is only ever a need for one initiative, then this is fine, but if it is expected that many initiatives will be needed, then this adds additional cost to the next initiative...
