System Definition
Must address at least:
system objective (intended purpose);
system functions and elements (including human, technical, and operational elements);
system boundary including other interacting systems;
physical (interacting systems) and functional interfaces;
system environment (e.g. energy and thermal flow, vibrations, electromagnetic interference, operational use);
existing safety measures – and the definition of any additional identified safety requirements;
assumptions that determine the limits for the risk assessment.
