Data Mining Standard Process (CRISP–
DM)
• A cross-industry standard was clearly
required that is industry neutral, toolneutral, and application-neutral
• The Cross-Industry Standard Process for Data
Mining (CRISP–DM) was developed in 1996
(Chapman, 2000)
• CRISP-DM provides a nonproprietary and
freely available standard process for fitting
data mining into the general problem-solving
strategy of a business or research unit

1. Business Understanding Phase
• Enunciate the project objectives and requirements
clearly in terms of the business or research unit as
a whole
• Translate these goals and restrictions into the
formulation of a data mining problem definition
• Prepare a preliminary strategy for achieving these
objectives
8
2. Data Understanding Phase
• Collect the data
• Use exploratory data analysis to familiarize yourself
with the data and discover initial insights
• Evaluate the quality of the data
• If desired, select interesting subsets that may
contain actionable patterns
9
3. Data Preparation Phase
• Prepare from the initial raw data the final data set
that is to be used for all subsequent phases. This
phase is very labor intensive
• Select the cases and variables you want to analyze
and that are appropriate for your analysis
• Perform transformations on certain variables, if
needed
• Clean the raw data so that it is ready for the
modeling tools
10
4. Modeling phase
• Select and apply appropriate modeling techniques
• Calibrate model settings to optimize results
• Remember that often, several different techniques
may be used for the same data mining problem
• If necessary, loop back to the data preparation
phase to bring the form of the data into line with
the specific requirements of a particular data
mining technique
11
5. Evaluation phase
• Evaluate the one or more models delivered in the
modeling phase for quality and effectiveness before
deploying them for use in the field
• Determine whether the model in fact achieves the
objectives set for it in the first phase
• Establish whether some important facet of the
business or research problem has not been
accounted for sufficiently
• Come to a decision regarding use of the data
mining results
12
6. Deployment phase
• Make use of the models created: Model creation
does not signify the completion of a project
• Example of a simple deployment: Generate a report
• Example of a more complex deployment:
Implement a parallel data mining process in
another department
• For businesses, the customer often carries out the
deployment based on your model
