Why margin? We call the combined interaction between fuels, weather and topography “Fire in the third dimension.” Cool title–heavy stuff really. Who thinks three-dimensionally? Spock? Add the human element into the equation (opinions, emotion, biases, beliefs, etc.) and welcome to the fourth dimension of firefighting: fuel/weather/topography/people. Good luck with that one; it’s too many variables to consider. The complexity of the fourth dimension of firefighting will quickly outpace our cognitive ability. The biggest supercomputer would be unable to process all of the potential interactions and outcomes of a large complex fire with hundreds of people and Mother Nature running wild.

What about Risk and Probability?
Viewing risk through the probability/severity model has value. It is a good equation if we know all of the knowns and unknowns and have large amounts of accurate data AND we operate in a system capable of absorbing error. A casino survives by the probability model, it has probability in its favor–it will win most of the time so it can afford to lose occasionally. How much loss can we absorb with 500 firefighters on the line? 5,000 firefighters? How rare are those anomalies like plume domination and unforecasted weather events or someone reading the map incorrectly? They are not rare. They are the norm. Do we plan for the norm–for the lowboy to get jackknifed on the escape route? On the fireground, unknowns will appear and error will happen. Our current use of the probability model does not embrace error; it attempts to reduce, eliminate or at times, ignore it. Margin recognizes error. It plans for it. It expects it. Error = reality and it lives side by side with success.
Why margin? Because we suck at measuring and understanding probability. Walk into any casino. Buy a lottery ticket. Eat a candy bar. Turn the music up. Text while driving…all of these actions are based on emotion, not data. Data says they are all bad yet we do them anyway. Why, because it feels good. Humans are naturally optimistic. We are emotional critters, not computers. We suck at measuring and understanding probability because it is boring and it doesn’t always give us the answer we want. We all see ourselves as potential lottery winners. What if we saw ourselves as potential causalities?
Look at the difference in these two questions:
- What is the probability of success?
- How much margin do we have?
Probability in our business is cradled in the hands of Mother Nature and the decision-making of the individual. We may have great maps, an accurate weather forecast and we may have analyzed the predicted rates of spread down to a fraction. But what if we looked at risk from the perspective of the stressed out, physically- and mentally-fatigued, color-blind decision maker operating in a complex environment (forest fire qualifies as a complex environment, don’t you think?). What if we planned for something unexpected to happen? We botch the handoff, the burnout is too hot. We fumbled on the two-yard line, the safety zone was labeled wrong on the map. What then would risk look like? What if we viewed risk as a metric for uncertainty rather than a measure of probability?
We would be discussing margin.
Remember that next time you are asked “What is the probability of success?” You may want to focus on margin. Or you can just punt.

Very nicely written piece. I agree that we need to take the time to re-group - 'create margin' and plan our next steps rather than fighting fire by habit and doubling down on risk.
