What Business Can Learn from Military and Medical Decision-Makers

Military leaders, battlefield medics, and surgeons all share a daunting reality: their decisions can mean the difference between life and death. The stakes are brutally high, the pressure constant, and the margin for error razor-thin. They must act fast, often with incomplete information, in dynamically shifting environments where waiting for certainty is not an option.

Fortunately, most business and organisational leaders operate in a very different context. While the consequences of a wrong decision can still be costly - commercially, reputationally, or operationally - they are rarely fatal. Yet the conditions in which decisions must be made are becoming increasingly similar: fast-moving markets, incomplete data, rising complexity, and the ever-present fog of uncertainty.

So what can we learn from those whose decision-making environment is unforgiving?

1. ⁠Prepare Relentlessly for Uncertainty Military and medical professionals train not just for known procedures, but for unpredictable, fluid scenarios. They drill decision frameworks under stress. In business, this means rehearsing responses to disruption, practicing scenario planning, and ensuring leaders are prepared to act, not just react.
   

2. ⁠Focus on First Principles, Not Just Protocols

   In the field, rigid adherence to procedure can be deadly. Leaders in combat or surgery rely on judgement shaped by principles, experience, and constant reassessment. Business leaders, too, must go beyond the manual - understanding why things work, not just how, in order to improvise effectively when reality veers off-script.
   

3. ⁠Build Teams That Think Under Pressure

   Decisions are rarely made in isolation. High-stakes environments rely on distributed leadership - trained teams that know when to speak up, challenge, and support the leader’s judgement. Cultivating that same trust and capability in corporate teams can radically improve both speed and quality of decision-making.

   
   

4. ⁠Make the Best Decision You Can - Then Move

   The military has a saying: “A good decision now is better than a perfect decision too late.” The cost of inaction can outweigh the cost of a wrong call. In business, perfectionism is often a mask for indecision. Learning when 70% certainty is enough is a skill worth developing.
   

5. ⁠Review, Learn, Improve - Without Blame

   After-action reviews in the military and medicine are rigorous, honest, and aimed at learning, not punishment. Business needs more of this. A culture where mistakes are examined without ego allows decision-making to improve exponentially over time.

The truth is, we don’t need to face life-and-death choices to benefit from the disciplines of those who do. Borrowing their mindset - underpinned by clarity, composure, and consequence-awareness - can elevate business leadership far beyond its current norms.

And if we can make faster, better decisions with fewer regrets, maybe that’s exactly the kind of edge we need.
