Document Scope
This handbook provides guidance on selecting the appropriate ORU items to ensure
that a flight system is supportable on-orbit. It addresses:
• The need for an ORU selection process.
• The ORU selection as an integral function of systems engineering and the
supportability engineering processes.
• The key decision logic and selection criteria for the MSFC ORU Selection
Methodology.
• Important design aspects that should be considered for ORU items.
