Abstract
The rapid pace of development of new systems coupled with a strong desire from warfighters to
quickly field systems with advanced technologies and innovation poses new Test and
Evaluation (T&E) challenges. These challenges start with the realization that most T&E
procedures are derived from a historical, requirements-based approach to acquisition, which
inherently is a sequential process. For innovative and unprecedented systems, i.e., the kind of
system for which there is no experience in building similar systems or in their test or use, T&E
cannot follow a sequential approach. Throughout military history, development of
unprecedented systems has occurred when there has been a simultaneous advance in technology
and operational need such as is occurring now in the domain of unmanned systems. T&E needs
to evolve to be integrated with the development process. Waiting for the results of developmental
and operational testing will only exacerbate the delay in rapidly fielding advanced capabilities.
This article presents the tenets of using the system engineering and test approach for evaluating
unprecedented systems and moving testing to the forefront of the system development process.
