MSFC-HDBK-3074, SELECTION METHODOLOGY FOR ORBITAL REPLACEABLE UNITS (11 DEC 2002)

MSFC-HDBK-3074, SELECTION METHODOLOGY FOR ORBITAL REPLACEABLE UNITS (11 DEC 2002)., This handbook offers guidance on a subset of the supportability engineering process by focusing on the identification of the orbital replaceable units (ORUs), their associated issues, and integrating this activity as part of an overall systems engineering process. This handbook does not present a "cookbook" approach to ORU selection; rather it does offer guidance, examples and issues to consider as the project’s ORU selection criteria are developed. The examples provided are just that - examples only. They are not meant to be a definitive solution; rather they provide insights to aid development of an innovative solution for the project's particular needs.
