Practical tip
The FAA is the biggest DOT buyer by far, spending over $3 billion per year on contracts. FAA uses its own acquisition management system (FAST) and has unique procurement procedures. If you target DOT, learn FAA's processes specifically rather than relying on standard FAR procedures alone.
