WHAT TO LEARN NEXT
THE MODEL STOPS HERE
Numbers do not make the whole decision.
Before acting, explicitly consider these factors outside the financial model:
YOUR DECISION BRIEF
Decision support, not advice. Results depend entirely on the economic structure, assumptions and ranges you provide. Shared links include confirmed options and assumptions, but not your original free-text wording.
