Evaluation Overview

At this point, you've completed most of your data mining project. You've also determined, in the Modeling phase, that the models built are technically correct and effective according to the data mining success criteria that you defined earlier.

Before continuing, however, you should evaluate the results of your efforts using the business success criteria established at the beginning of the project. This is the key to ensuring that your organization can make use of the results you've obtained. Two types of results are produced by data mining:

• The final models selected in the previous phase of CRISP-DM.
• Any conclusions or inferences drawn from the models themselves as well as from the data mining process. These are known as findings.
