Design & Consultancy Services EADS North America Defense Test & Services provides consultancy and design services for the development and production of test equipment. We work with customers in ascertaining the full range of test needs, and in the absence of a defined support strategy will offer cost-effective options. Assistance can be provided to customers by performing testability analysis of their requirements and addressing potential through-life costs associated with options involving either "fielded" test solutions or "return to work" strategies.
