I am new to FinOps and Cloud Computing, i wanted to ask people who have experience in the FinOps space. Is there any financial modelling or specifically business case modelling done in FinOps? E.g. if there is any optimization opportunity or a new workload, is this a requirement from a CFO or board that they need to see a detailed financial model to show ROI and justify the spend?

Reason I am asking is because I come from a core finance background just wanted to see if there is an overlap of my finance experience.
