Defense Acquisition Cost Analysis
Analyze defense acquisition costs, identify drivers, compare contract vehicles
What You Can Do
You can systematically evaluate contractor proposals, break down cost drivers by work breakdown structure (WBS), compare fixed-price versus cost-plus contract vehicles, and validate estimates against historical benchmarks and analogous programs. This skill helps you conduct should-cost analyses, identify cost growth risks, assess schedule-cost tradeoffs, and prepare acquisition strategy recommendations with defensible cost baselines that support program decision-makers.
Features
Decompose proposals by WBS to isolate labor, material, overhead, and G&A components driving total program cost
Evaluate risk/reward tradeoffs across fixed-price, cost-plus, incentive, and performance-based contract structures
Benchmark contractor estimates against historical data, industry standards, and analogous programs to flag outliers and fairness concerns
Track and project cost trends over program lifecycle, flagging schedule slip and technical risk impacts on baseline
Align cost analysis with schedule performance metrics and earned value management (EVM) reporting
Quantify cost and schedule effects of scope changes, constraint modifications, and contractor claims
Compare in-house production costs against outsourcing proposals with risk-adjusted lifecycle totals
Build contingency reserves and confidence levels tied to technical maturity, supplier performance, and schedule risk
Example Output
Example 1: Proposal Cost Breakdown Analysis
- WBS Level 3 Cost Summary
- Engineering: $45M (labor rate benchmarked vs. comparable programs)
- Manufacturing: $78M (material @ 18% above industry average — flagged for clarification)
- Integration & Test: $22M (schedule-critical, recommend fixed-price incentive)
- Total: $145M (12% above should-cost estimate — recommend value engineering workshop)
Example 2: Contract Vehicle Recommendation
- Fixed-Price Development (Low): Risk to contractor; requires mature specs (maturity level 3 minimum)
- Cost-Plus-Fixed-Fee (Recommended): Shares technical risk; supports rapid prototyping; cost ceiling $155M
- Incentive Structure: +/- 10% fee adjustment tied to cost performance index targets
Example 3: Cost Growth Risk Flag
- Supplier lead times extend schedule 6 months; downstream cost impact: +$8.2M labor
- Recommend: Parallel long-lead procurement or contract modification authority
