## If unit costs of a Major Defense Acquisition Program increase >25%, then DoD (as delegated to USD(AT&L) must certify that all of the following four criteria are met, or no further appropriated funding can be obligated on major contracts:
Such acquisition program is essential to national security
There are no alternatives to such acquisition program which will provide equal or greater military capability at less cost
The new estimates of the program acquisition unit cost or procurement unit costs are reasonable
The management structure for the acquisition program is adequate to manage and control program acquisition unit cost or procurement unit cost
Certificate must apply to whatever program goes forward, which is not necessarily the program of record
If program going forward differs too much from program of record, then cannot certify; such a program must instead be proposed as a “new start”
Even if a program is certifiable, USD(AT&L) can choose not to certify
