A critical part of successful technology transition is the demonstration of technology and research results in a context that is meaningful to users. Within such an operational context, application developers in the Advanced Research Projects Agency/Rome Laboratory (ARPAJRL) Planning Initiative (ARPI) integrate, apply, and demonstrate technology to produce Integrated Feasibility Demonstrations (IFDs). IFDs provide both a pull on research and development and a push of technology into operational settings. This pape? describes the three IFDs that have been conducted since the program began, as well as the current IFD, scheduled for presentation in May 1996. In addition to describing the operational problem and technical solution that each IFD addressed, we present the lessons learned from each and the overall methodology that is used in planning and conducting IFDs. Finally, we present other mechanisms of technology transfer besides IFDs, and give an example of a lateral technology transfer.
