McKinsey SFL
Rank the flood program like a year-one budget
Port Casilda, 18 months out, tight budget. Five initiatives. Cheap and reversible first. Eight-minute clock. Independent. Not affiliated with McKinsey.
How to structure the ranking
This is not a case tree. It is a sequence under a budget. Rank by year-one lives per dollar, then kill anything that takes a decade.
- Metric. Year-one lives saved per dollar. Not total lives in 2035.
- Tie-break. Reversibility. Fast and cheap beats a wetland you cannot unbuild.
- Kill one. Say out loud which initiative loses. That is the grade.
“Early warning first — cheap, year-one lives, reversible. Then pump upgrades. Wetlands last: they take a decade and the budget is 18 months.”
Usual miss. Leading with the seawall because it sounds like infrastructure, or ranking wetlands first because they save the most lives eventually.

FAQ
Is this the real McKinsey SFL module?
