Title: Discussion
Course: Advanced Data Science: A Graduate Course > Section: Module 8: The RiverCity consulting engagement and defense

Interaction is structured as three check-in posts spread across the three weeks, each requiring a substantive peer response and each answered by the instructor acting as the RiverCity client contact. The scoping post (Week 13) shares your intake note and evaluation plan and asks one pointed question about scope or measurement; peers respond by stress-testing the leakage-safe plan, and the instructor responds in role with client priorities and constraints. The milestone post (Week 14) shares interim resampled performance and the risks you are watching; peers respond by probing the weakest assumption, and the instructor responds with a client’s reaction to the emerging recommendation. The post-drift reflection (Week 15) reports what the Evidently analysis revealed, how you diagnosed the shift, and what you changed; peers respond by challenging the diagnosis or the adaptation, and the instructor closes the loop in role and confirms readiness for the defense. Substantive means engaging the specifics of a peer’s decisions, not general encouragement.
