DoD Experience with the C4ISR Architecture Framework

The Department of Defense (DoD) is mandating the use of the Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance Architecture Framework (C4ISRAF) for large-scale software-intensive systems. The authors conducted eight interviews with personnel who have used the C4ISRAF in acquisition projects. The intent of the interviews was to find the strengths and weaknesses of the C4ISRAF, so that this information could be communicated to future users of the framework. This technical note discusses the context for using the C4ISRAF, the observations made during the interviews about its use, and the strengths and challenges of using it. Suggestions for overcoming these challenges also are included.
