MSE is an 11.25m telescope with a 1.5 sq.deg. field of view. It can\nsimultaneously obtain 3249 spectra at R=3000 from 360-1800nm, and 1083 spectra\nat R=40000 in the optical. Absolutely critical to the scientific success of MSE\nis to efficiently access the faint Universe. Here, we describe the adopted\nsystems engineering methodology to ensure MSE meets the challenging sensitivity\nrequirements, and how these requirements are partitioned across three budgets,\nrelating to the throughput, noise and fiber injection efficiency. We then\ndescribe how the sensitivity of MSE as a system was estimated at the end of\nConceptual Design Phase, and how this information was used to revisit the\nsystem design in order to meet the sensitivity requirements while maintaining\nthe overall architectural concept of the Observatory. Finally, we present the\nanticipated sensitivity performance of MSE and describe the key science that\nthese capabilities will enable.\n
