Module 5 Lab: Generative AI for marketing operations

Design a governed content workflow.

Lab Context

This lab uses synthetic customer records with engagement, recency, spend, channel preference, and consent state as a safe proxy for the course setting. It is not a substitute for institutional data, but it lets you practice the reasoning, metrics, and documentation pattern before working with real records.

Lab Tasks

1. Run the baseline analysis.

2. Identify the decision the metric supports.

3. Change one threshold, score weight, or input assumption.

4. Compare the result before and after your change.

5. Record one deployment risk that the synthetic data cannot reveal.
