Multiple Hazard analysis and project breakdown

Question

Hello,     Since our systems are composed by a master system (more or less a railway system) and subsystem(s) that, for some of them, are an automotive system, I would <?WORD FLAGGED?> to know what is the best way to manage my master system (and especially for the Hazard Analysis):     (1) Can/Should I create multiple independ Hazard analysis in the same master project (one for the master system and for example an HARA kind for subsystems)?     (2) Can/Should I create multiple project with different kind of template? And then how can I reference the master project to its subsystem's project (especially for traceability)?     (3) No solution for now...     For (1) or (2) I need to keep traceability and capability to reference hazard elements between those analysis.     Thank you in advance for your help.     Romain D.

Hello,     We've eperienced something quite similar where I work (basically how to deal with a system/subsystem split). What we've done which works really well is to have a Master project (which contains the system) and one projet per subsystem which are derived directly from the Master project (derived and cleaned of information not related to the subsystem).      Once in a while we merge everything from the subsystems projects (analyses, models, requirements) back to the system project.      From what we've tested, we can create each subsystem project in a different domain (by merging the whole system project) and then merging into the system project will not cause any issues - except you cannot reliably modify the subsystem analyses in the system project. This is not a problem for us as we decided to never modify subsystem information in the system project.     I don't know if that can help you,     Adrien

Thank you for your answer.  I will try implementing both hazard analysis in the same project but using different customized columns.
