providers, users of the air transportation system, and the national economy as a whole. The JPDO Integrated Plan discusses the importance of demand, but often in the context of other objectives that are given equal or greater weight.

Recommendation 2-1. Demand. The Integrated Plan should clearly state that increased demand is the key driver that mandates implementation of the Next Generation Air Transportation System. The JPDO should refocus its efforts on development of a systematic, risk-based approach for achieving the primary objective, which is to resolve demand issues and increase capacity, while also satisfying enabling, interrelated requirements for safety, security, environmental effects, consumer satisfaction, and industrial competitiveness. The Integrated Plan should make sure that secondary objectives, such as alignment of existing interagency efforts, do not overshadow the primary objective. The JPDO should establish goals related to cost, schedule, and level of performance that can be quantified using appropriate figures of merit. Multiple candidate scenarios and operational concepts should be defined and assessed in terms of the risk that they will fail to achieve these goals.
