Administrative agreements officers of the Defense Contract Management Agency and the Office of Naval Research can share lessons learned from administering other TIAs. Program officials can be a source of information when you are determining the reasonableness of proposed funding (e.g., on labor rates, as discussed in §37.520) or establishing observable and verifiable technical milestones for payments (see §37.575). Auditors at the Defense Contract Audit Agency can act in an advisory capacity to help you determine the reasonableness of proposed amounts, including values of in-kind contributions toward cost sharing.
