RSDI engineers are experienced in the development of complex systems from requirements development to fielding. Our team has worked on a number of programs in the planning stages. For example, as part of the CTC OIS Communications infrastructure effort, we supported requirements derivation and development, communications architecture development, network traffic modeling and simulation to include analyzing numerous sources of data from which to develop the models. Our experience has been called upon a number of times to support remediation of program requirements and systems engineering processes in support of programs that could not pass government standards.
