... In the commercial world, reducing product development cycle time helps manufacturers increase their market share by enabling them to create new and better products faster than the competition. In the government sector, reduced product development cycle time helps agencies complete projects sooner, thereby reducing costs and improving services or achieving mission objectives more quickly and freeing personnel and fiscal resources to move on to the next task.

... Complex products and missions typically are implemented by partnerships of many different organizations, and the AEEs adopted by one organization will be more useful if its partners use compatible AEEs. To achieve widespread use of AEEs, industry and academia must establish appropriate training and educational programs for current and future workers.

... 23 Hardware and Networks Ultrafast computing systems will be needed to support the real-time analyses and interfaces described above. These systems will probably involve massively parallel processors and, ultimately, a distributed heterogeneous computing capability to maximize computing power economically.

... In the long-term, aggressive implementation of complete AEE systems has the largest potential payoff, but it also has the largest risks and highest costs. Staged implementation of AEE technologies is likely to outperform evolutionary improvements in conventional technology.
