The team is working to build a data preparation pipeline for the conversational chatbot project. Which phase of CPMAI is this done?

CPMAI Phase III (Data Preparation) covers cleansing, transforming, and pipeline construction to feed subsequent model-building activities. Creating the data preparation pipeline for the chatbot therefore occurs in Phase III.

A – Phase I focuses on business understanding, not data work. B – Phase II addresses data collection and initial exploration, not full preparation pipelines. D – Phase IV is model development. E – Phase V concerns model evaluation. F – Phase VI handles deployment & monitoring, after data prep is complete.
