Which office is responsible for independent assessment of the effectiveness and suitability of new weapon systems?

• A. Congressional Budget Office
• B. GAO
• C. Director, Operational Test & Evaluation (DOT&E)
• D. Office of the Secretary of Defense

Answer: (C)

Independent evaluation of a new weapon system focuses on testing how well the system performs in realistic conditions and whether it is suitable for use by the armed forces. The Director, Operational Test & Evaluation oversees planning, conducting, and reporting these independent operational tests and evaluations. This office provides objective judgments on the system’s effectiveness (can it accomplish its missions) and suitability (reliability, maintainability, safety, interoperability, and overall operability), along with any risks or deficiencies. These independent results inform key decisions on whether to proceed, modify, or terminate a program.

Other offices have different roles: the Congressional Budget Office analyzes costs and economic impact, the GAO conducts audits and investigations across government programs, and the Office of the Secretary of Defense handles policy and management. They do not perform the dedicated independent testing and evaluation of new weapon systems.
