Which CPMAI phase focuses on assessing available data sources?

• A. Data Understanding
• B. Data Preparation
• C. Deployment
• D. Monitoring

Answer: (A)

The main idea is that assessing what data is available happens in Data Understanding. In CPMAI, this phase is all about exploring the data landscape: what data exists, where it comes from, how complete and trustworthy it is, how easy it is to access, and any governance or privacy constraints. This helps you determine whether you have enough relevant data to proceed, identify gaps, and plan on what data you may need to acquire or integrate. Once you have a clear view of the data sources and their quality, you move into Data Preparation, which focuses on cleaning, transforming, and combining the data for modeling. Deployment is about putting the model into production, and Monitoring tracks performance and data drift once it’s live. So, the phase that most directly concerns assessing available data sources is Data Understanding.
