A project manager moves to a new division and takes over an agile project in an unfamiliar domain. To understand the project risks, what primary tool should the project manager use?

Collaborative discussions are the most effective primary tool in this scenario because they leverage the collective knowledge of the existing team, who are already familiar with the project and its domain. This allows the new project manager to quickly gain insights into potential risks, their impacts, and existing mitigation strategies. Workshops for risk avoidance are a risk response strategy, not a primary tool for initial risk identification and understanding. Probability assessments are a quantitative risk analysis technique, which comes after initial identification and qualitative analysis. An interview with only the project champion would provide a limited perspective; a broader discussion with the team is necessary for comprehensive risk understanding.
