Many brilliant minds, both Rubin employees and those in the scientific community, are already supporting the goal of proving that we have built the observatory that we said we would build and that it performs to a level that we said it would perform to. This will be true from the smallest components to the full observatory and from the engineering side to the science it enables. Many more are needed to complete this task. If you like to be one of them, this session is for you! Here we will present the process of developing the test plan, collecting the results, and providing the reports. We connect the requirements written in the distant past to today’s summit activities on verification and validation to tomorrow’s sign-off with the agencies. On this journey, we touch on the Model-Based System Engineering methods in use here at Rubin and describe the usage and connection between our tools JIRA and MagicDraw.
