The starting point and primary source material for this project was a collection of the Defense Department's annual Contract Action Data Files from fiscal years 1998-2003. These databases, totaling a combined 2.2 million records, document all activities concerning contracts with values exceeding $25,000. Each record includes a wealth of detail, based on the Pentagon's DD Form 350, which must be filled out every time a contract action takes place.
All the data refers only to contracts authorized to the prime contractor. Subcontractor information is not publicly released.
All references to "contracts" throughout the report refer to the dollar amount of the contracts, rather than the number of contracts. For instance, a statement that a particular company got two-thirds of its contracts through sole-source bidding would mean two thirds of the contract dollars were won through sole-source bidding.
The Defense Department has been compiling this data since 1966, and all the databases are available for downloading on the web at www.dior.whs.mil/PEIDHOME/guide/procoper.htm.
Among the data include in those records are the prime contractor's name, address, Dun & Bradstreet ID number, corporate parent ID (unfortunately, not always accurate), the contracting office, the dollar amount of the new or amended contract, the location where the work was performed, a description of the product or service provided, and detailed information about the type of contract, whether it was competitively bid or not, whether it went to a small or large business—even how many bidders responded.
Databases from earlier years, as far back as fiscal 1984, were also used to track long-term shifts in the goods and services the Pentagon bought.
