Projects and Reports
CRISP-DM View
By supporting the Cross-Industry Standard Process for Data Mining (CRISP-DM), IBM® SPSS®
Modeler projects provide an industry-proven and non-proprietary way of organizing the pieces
of your data mining efforts. CRISP-DM uses six phases to describe the process from start
(gathering business requirements) to finish (deploying your results). Even though some phases
do not typically involve work in SPSS Modeler, the project pane includes all six phases so that
you have a central location for storing and tracking all materials associated with the project.
For example, the Business Understanding phase typically involves gathering requirements and
meeting with colleagues to determine goals rather than working with data in SPSS Modeler. The
project pane allows you to store your notes from such meetings in the Business Understanding
folder for future reference and inclusion in reports.

The CRISP-DM view in the project pane is also equipped with its own Help system to guide you
through the data mining life cycle. From SPSS Modeler, this help can be accessed by clicking
through the data mining life cycle. From SPSS Modeler, this help can be accessed by clicking
CRISP-DM Help
on the Help menu.
Note: If the project pane is not visible in the window, click
Project
on the View menu.
Setting the Default Project Phase
Objects added to a project are added to a default phase of CRISP-DM. This means that you need
to organize objects manually according to the data mining phase in which you used them. It is
wise to set the default folder to the phase in which you are currently working.
