Input	Process	Output
– Life cycle concepts – System function identification – Stakeholder requirements – Stakeholder requirements traceability – Initial RVTM – Architecture traceability – Final RVTM – Life cycle constraints	> Prepare for system requirements definition > Define system requirements > Analyse system requirements > Manage system requirements	= System requirements definition strategy = System function definition = System requirements = System functional interface identification = Verification criteria = MOP needs = MOP data = System requirements traceability = Updated RVTM = System requirements definition record
