Scaled Agile Framework (SAFe) Release Train Engineer Practice Test

What metric is used as the denominator in WSJF calculations?

1. Job size based on relative estimation

2. Feature size expressed in Story points

3. Feature size expressed in a T-shirt size

4. The actual business value of a Feature

The correct answer is: Job size based on relative estimation

In the Weighted Shortest Job First (WSJF) calculations, the denominator is focused on the job size or effort required to complete a particular feature or piece of work. The rationale behind using job size based on relative estimation is that it allows teams to assess how much work is involved in relation to the potential value delivered by that work. This relative sizing helps prioritize features effectively, ensuring that those with the highest potential return on investment are addressed sooner. Using a relative estimation for job size fosters a collaborative approach within teams, where members can share their insights and come to a consensus on the complexity of various tasks. It facilitates a more nuanced understanding of effort, as traditional story points or T-shirt sizes might not capture the full context of the work involved. Choosing job size as the denominator allows organizations to adopt a more balanced view of both value and effort, aligning with the core principles of the Scaled Agile Framework where maximizing value delivery is of utmost importance.
