What is the term used for testing two strategies against each other?

The term "Champion Challenger" refers specifically to the method of testing two strategies against each other in order to evaluate their effectiveness. In this context, one strategy is designated as the "Champion," representing the current best-performing approach, while the other is the "Challenger," which is an alternative strategy or variation that is being tested for potential improvements.

This methodology allows organizations to empirically determine which strategy yields better results through controlled testing and performance measurement. By comparing these strategies directly, data-driven decisions can be made about which approach to continue using or to implement more broadly.

While other terms may imply comparisons or assessments of strategies, they do not capture the specific dynamic and methodologically rigorous framework that the Champion Challenger approach embodies.
