Defining Business Intelligence Quality
Critical to Quality Factors for BI.
Information quality is the degree to which the transformed (e.g. from a data warehouse) data is free of defects which limit usefulness as a business intelligence resource. Information defects may occur when the translation from data to information occurs within a data warehouse. The information defects may result from defective 'raw' data or they may result from the translation process. Information defects are of two types:
• Materials defects occur when using the wrong data, or when using data of poor quality to produce information. When data of poor quality is used, data defects are translated into information defects.
• Presentation defects occur when information is delivered in a form that is unreliable, inconsistent or subject to misunderstanding. Presentation quality means that information is delivered in a useful and understandable form.
Information quality improvements are focused more on people than procedure. Information quality strategies focus on preventing and removing defects when information is delivered from the warehouse and used to make business decisions. Tools and tactics include metadata, education, training and support.

CTQ: Information
The degree to which the presentation makes the information useful and understandable, i.e. has the data has been translated for its intended use.
We measure defects in terms:
Defects in the raw materials, i.e. the data. These defects occur when using the wrong data, or when using data of poor quality.
Presentation defects occur when information is delivered in a form that is unreliable, inconsistent or subject to misunderstanding. Presentation quality means that information is delivered in a useful and understandable form.
