Enhancing and cleaning data is an important action during which phase of CPMAI?

The CPMAI™ v7 methodology groups all data-centric preparation activities—including both data cleansing (“Clean data”) and data augmentation (“Enhance & Augment data”)—into Phase III: Data Preparation. In this phase, teams focus squarely on constructing the dataset to be used for modeling by performing all required cleaning, transformation, and enhancement operations.

Phase III: Data Preparation is defined in the Workbook’s Table of Contents as covering Data Cleansing & Enhancement tasks (“Clean data” and “Enhance & Augment data”) .

Under Phase III, the Generic Task Group: Data Cleansing & Enhancement explicitly lists “Task: Clean data” (bringing data quality to modeling-ready levels) and “Task: Enhance & Augment data” (producing derived attributes and new records) as core activities .
