In the SAFe context, jobs are the Features, Capabilities, and Epics contained in their respective backlogs. For example, if implementing a prospective feature would be worth 100,000 per month, and there was a delay of three months, the total CoD would be 300,000. It’s a measure of the economic value of a job over time. Simply put, CoD is the money lost by delaying or not doing a job for a specific time. In Principles of Product Development Flow, Reinertsen describes a model (WSJF) for prioritizing jobs based on the Cost of Delay. WSJF also conveniently and automatically ignores sunk costs, a fundamental principle of Lean economics. Backlogs are continuously prioritized based on a WSJF algorithm that uses relative user and business value, time criticality, risk reduction and/or opportunity enablement, and job size. To that end, SAFe applies WSJF to prioritize backlogs. In other words, job sequencing produces the best results rather than prioritization based on a theoretical return on investment for each job. In a flow-based system, priorities must be continuously updated to provide the best economic outcomes. In SAFe, WSJF is estimated as the relative cost of delay divided by the relative job duration. Weighted Shortest Job First (WSJF) is a prioritization model used to sequence work for maximum economic benefit.
