What is the clearest definition available of the type of performance improvement significant enough (for an existing application) to require RTD&E funds vs. O&M?
The DoD Financial Management Regulation does not provide strictly objective criteria for what qualifies for use of RDT&E funds, but DoD Financial Management Regulation 7000.14-R, Volume 2B, Chapter 5, paragraph 050105
provides general guidance. Just as importantly, DoD Financial Management Regulation 7000.14-R, Volume 2A, Chapter 1, paragraph 010213
states "When, after consideration of the following criteria, there is doubt as to the proper assignment of costs between appropriations, the issue should be resolved in favor of using RDT&E funding."
