Handling correlated systematic uncertainties on the CKM angle gamma

The current precision on the CKM angle $\gamma$ is driven by averages of measurements from multiple final states and multiple experiments. As the next generation of experiments targets a total experimental precision on $\gamma$ less than one degree, systematic uncertainties must be well-controlled and correlated uncertainties between different final states and across experiments must be fully understood. These proceedings examine the systematic uncertainties that arise in direct measurements of $\gamma$ and discuss the potential of each class of systematic uncertainties to prevent sub-degree precision.
