Rubin systems engineering processes for image quality tracking, CMMS selection, FRACAS handling, and hazard mitigation analysis

The Vera C. Rubin Observatory is one of the first observatories to apply Model-Based Systems Engineering in all major aspects of the project. This paper describes the evolution of the processes, methodologies and tools developed and utilized by the Rubin Observatory Team. It specifically focuses on the Rubin Systems Engineering Processes for Image Quality tracking, Computerized Maintenance Management System (CMMS) selection, Failure Reporting, Analysis, Corrective Action System (FRACAS) handling, and Hazard Mitigation Analysis. Here, we share updates on each topic's workflows, experiences, and difficulties with the community.
