Intelligence cycle is a theoretical model quite criticized but fairly coherent and insufficiently explored. With its four “core functions” (direction, collection, processing and dissemination), it may adequately describe the structure of an intelligence community (command structures, collection teams, exploitation or analysis services, communication structures) in a systemic approach (who does what?), but it does not describe the intelligence process (what does intelligence function? how to make intelligence?).
