A Conceptual Framework for the Application of Systems Approach to Intelligence Operations: Using HUMINT to Augment SIGINT

There are terrorist groups around the world whose primary mission is to inflict as much harm on American interests and citizens as possible. These groups have to be successful only once, as 9/11 taught us, but stopping them requires a 100% success rate of homeland security and national defense efforts. This means having to be right a large percentage of the time in assessing threats and in effectively deploying adequate resources to minimize the risks. This requires robust intelligence gathering and application to execute preemptive strikes. The premise of this article is that the more systems modeling is applied to an intelligence strategy, the more robust the strategy will be. There will never be sufficient resources to meet every threat. The problem is to deploy available resources judiciously in the most effective manner so that the overall risk of a terrorist attack is minimized. In this article, we propose the application of the DEJI (Design, Evaluation, Justification, and Integration) systems engineering model to intelligence applications. Specifically, we propose applying the DEJI model in a conceptual framework by using HUMINT (human intelligence) to augment SIGINT (signals/sensor intelligence) from a systems perspective.
