Level: Intermediate

How can you measure the quality of something if you don’t know what it is in the first place? Good, robust, precise definitions are central to the measurement of data quality. The definition of any data element should include an objective standard for measurement of that data element. This presentation will cover the following points:

• Why definitions are the key for data quality
• What are the components of a good, precise definition
• How the definition of fundamental business terms affect both the business and business metrics
• Why data quality metrics are business metrics
• How data quality affects the bottom line
• How do you measure 100%? And why this is important to the business
