war-gaming

In simple English

War-gaming in tech refers to a planning and risk-management technique where teams deliberately work through hypothetical situations and potential problems before they occur in production. Instead of waiting for issues to arise with real users, teams simulate what could go wrong—such as server failures, security breaches, or unexpected user behavior—and develop responses in advance. This term comes from military strategy where commanders simulate battles to prepare for real combat. In software engineering, it is used during product planning, infrastructure design, incident response planning, and before major releases. Teams might war-game a database migration, a security incident, or a traffic spike to ensure they are ready. The process typically involves writing out scenarios, identifying failure points, and agreeing on who does what if the scenario happens. War-gaming helps teams catch design flaws, clarify responsibilities, and build confidence before critical operations.

Understand what war-gaming means in software development and how to use it in your tech team.

Real examples

in a standup

"Before we deploy this payment feature, we need to war-game what happens if the payment gateway goes down."

"Let us spend an hour war-gaming the database migration so we know exactly what to do if something breaks."

in a postmortem discussion

"If we had war-gamed that scenario last month, we would have known how to respond when it actually happened."

Don't say this

Handle with care. Do not confuse with actual military strategy. In tech, it means simulating scenarios to identify problems, not competing against others.

✕We are war-gaming our competitors to win the market.
✓We are war-gaming different user scenarios to stress-test our system.— War-gaming in tech is about simulating problems, not competing against others. Use it only for internal scenario planning.
✕The war-gaming showed everything will work fine.
✓The war-gaming revealed three potential failure points we need to address.— War-gaming is meant to find problems and risks, not to confirm everything is fine. It should expose weaknesses.
