System Readiness Level Index

Revision as of 13:18, 14 February 2021

The System Readiness Level (SRL) index is an index of maturity applied at the system-level concept with the objective of correlating this indexing to appropriate systems engineering management principals ^[1]. The SRL of a given system is a function of individual TRLs and the maturities of the links between them, which will be defined based on a scale of integration readiness levels (IRLs). The resulting function of this interaction is then correlated to a five level SRL index. This SRL index is defined by the current state of development of a system in relation to the DoD’s Phases of Development for the Life Cycle Management Framework ^[2].
