C.1 This appendix provides considerations for designating a mission or instrument risk tolerance class. These considerations constitute a structured approach for identifying a hierarchy of risk tolerances commensurate with the four risk tolerance classes defined in Chapter 3.
C.2 The considerations provided are to be treated holistically with each taken into account in order to most appropriately designate a mission or instrument risk tolerance class based on the applicable mission criteria. The considerations provided in the table below are not definitive, nor is any specific mission criterion alone intended to be the ultimate driver to designating a mission or instrument risk tolerance class. Ultimately, the mission or instrument risk tolerance class is designated by the Mission Directorate in accordance with paragraph 3.1.4.
C.3 Other considerations for designating a mission or instrument risk tolerance class may exist that are not explicitly expressed in this appendix (e.g., alternate research or reflight opportunities, launch constraints).

|Life-Cycle Cost||High :||Class A|
|Medium to High||Class B|
|Medium :||Class C|
