Which model is used in SAFe to prioritize the ART Backlog elements?

The Weighted Shortest Job First (WSJF) model is used in SAFe to prioritize ART (Agile Release Train) Backlog elements. This approach helps organizations make decisions about what to work on next by balancing the cost of delay against the duration of implementation.

WSJF is calculated using the formula: Cost of Delay divided by the Job Size (the duration or effort required to complete a task). The Cost of Delay considers various factors such as urgency, business value, and risk reduction. By applying this model, teams can prioritize work that delivers the highest value in the shortest amount of time, ensuring efficient utilization of resources and faster delivery of key capabilities.

This prioritization method aligns well with SAFe's emphasis on delivering value quickly and effectively, enabling teams to focus on the most impactful items in the backlog.
