Systems Enginnering applied to spectroscopy of the ELTs: The Conceptual Design phase of GMACS

An important tool for the development of the next generation of extremely large telescopes (ELTs) is the Systems Engineering (SE). GMACS is the first-generation multi-object spectrograph working at visible wavelengths for the Giant Magellan Telescope (GMT). The aim is to discuss the application of SE in ground-based astronomy for multi-object spectrographs. For this, it is presented the SE of the GMACS spectrograph, currently on its Conceptual Design phase. SE provide means to assist the management of complex projects, and in the case of GMACS, to ensure its success when in operation, maximizing the scientific potential of GMT.
