User business value and time criticality are components of what?

User business value and time criticality are components of cost of delay. Cost of delay is a way of quantifying the economic impact of delaying the delivery of a product or feature. Cost of delay consists of four factors: user or customer value, time criticality, risk reduction or opportunity enablement value, and job size or duration. Cost of delay is used to prioritize features using Weighted Shortest Job First (WSJF), which is a method that maximizes the economic value delivered by a product development flow. References: ART Backlog and WSJF, SAFe Principle #1
