Which statement is true for estimating and forecasting in SAFe?

According to the Applying Lean Estimating and Forecasting in Cadence article on the Scaled Agile Framework website, ART velocities are used to conduct ‘what if’ analysis for estimating and forecasting in SAFe. The article states that “The ART velocity is used to conduct ‘what if’ analysis, which helps determine the feasibility of the plan and the number of features that can be delivered in a PI. The ART velocity is also used to forecast the delivery of features and capabilities beyond the current PI.” Therefore, the correct answer is C, ART velocities are used to conduct ‘what if’ analysis. The other options are not accurate, as they are not the statements that are true for estimating and forecasting in SAFe. Feature estimation is not independent of team-level input (A), as teams are involved in estimating the size and complexity of features using story points or normalized story points. Epics are not estimated by the Epic Owner (B), as they are estimated collaboratively by the Epic Owner, Enterprise Architect, and Lean Portfolio Management. Work breakdown structure to the task level does not help increase estimation accuracy (D), as it introduces unnecessary overhead and delays feedback.
