Although there is a “time to every purpose under heaven” (lyrics to the song Turn, Turn, Turn, by the Byrds) including a time and purpose for Cost-Type Contracts (FAR 16.3 Cost-Reimbursement Contracts), do not try to sing this song to Senator John McCain (Chairman of the Senate Armed Services Committee or SASC). In application to cost-reimbursement contracts, Senator McCain recently referred to cost-plus contracting as “an evil that has grown and grown and grown over the years, and I will not stand for it on any weapons system”. In support of his statement, there is a long history of significant cost overruns on major weapons systems which all started with cost-reimbursable developmental contracts. Unfortunately, comparing original cost estimates with final program costs, i.e., computing the percentage of cost growth, is a very simplistic and incomplete statistic noting that developmental contracts are just that, conceptual and lacking anything approaching a well-defined statement-of-work. As such, these agreements are not exactly candidates for a firm-fixed price contract (FAR 16.2), unless the prime contractor is naïve and/or reasonably sure that its risk will be mitigated by an endless series of change orders and requests for equitable adjustment for each and every change to the statement of work. As a point of reference explaining why a contractor should not be overly optimistic in terms of accepting a fixed-price contract with an ill-defined statement of work, one only needs to read the decision in US CoFC Nos. 13-55C, 13-97C, filed August 18, 2015. In particular, the judge rejected the contractor claim for increased costs noting that the contractor voluntarily assumed the risk of a firm-fixed price contract, albeit with an “unusually high risk” attributed to the ill-defined statement of work.
