Question

decision trees in project management are primarily used to:
track project risks, assumptions, issues, and dependencies.
determine the root cause of a problem..
evaluate costs and potential outcomes of decisions.
define roles and responsibilities.

Explanation:

Decision trees are a quantitative decision-making tool that map out decision alternatives, associated costs, and the probabilistic outcomes of each choice. This aligns with evaluating costs and potential decision outcomes. Tracking risks/assumptions is done via risk registers, root cause analysis uses tools like 5 Whys, and role definition uses RACI charts.

Answer:

Evaluate costs and potential outcomes of decisions.
