The Thirty Meter Telescope (TMT) uses error budgets to understand and track the expected science parameters of the Observatory. In this paper, we demonstrate how the top-level requirements for wavefront error in both Multi-Conjugate Adaptive Optics (MCAO) and Natural Guide Star Adaptive Optics (NGSAO) modes have been decomposed and allocated between various sources that may cause performance degradation. We also show how those values have been integrated into the requirements for each individual subsystem. By integrating these error budgets into our requirements management process, we are able to maintain traceability between science and design, and understand how changes at a low-level could affect the overall AO performance of the Thirty Meter Telescope.
