It will be installed on the straight-through port of the telescope Nasmyth platform to serve the first-light instrument MICADO and with the provision for a future second instrument. The module underwent the Preliminary Design Review in 2021 and is expected to be commissioned in 2029. In this paper we present a synthesis of the System Engineering approach adopted to manage the development of the instrument. We will discuss the evolution of the architecture towards the requirements. We will detail the criticalities of the system engineering with a particular focus onto the management of the interfaces between subsystems and external systems (Telescope, other instruments…). We will also make a brief description of way in which we implemented Model Based System Engineering and the tools adopted in order to manage requirements, use cases and interfaces.STAMPAenConference paper10.1117/12.26303532-s2.0-85178515992https://www.spiedigitallibrary.org/conference-proceedings-of-spie/12187/2630353/MORFEOELT-system-engineering-activity-up-to-preliminary-design-review/10.1117/12.2630353.fullhttps://api.elsevier.com/content/abstract/scopus_id/851785159922022SPIE12187E..1ORFIS/05 - ASTRONOMIA E ASTROFISICA
