The father of the North American Strategic Intelligence doctrine, which principles have been kept in effect for many years, established one of the problems that more motivates to investigators of Intelligence discipline to develop new approaches in the shape of procedures and methods. Sherman Kent, across his multiple works, established and dignified a frame of reference that allowed to turn Intelligence analysis functions into a knowledge workers' profession.In his studies around the intelligence "Doctrinal Corpus", that is, the Intelligence Cycle, he verified the problems associated with its structure and made it possible to unbind Intelligence from the cycle in strict sense, understanding this one as a procedural model of reality that can have more valid alternative models.

From Kent's point of view, the Intelligence cycle is a conventional approach of problems resolution, that is to say, it operates from the question (problem) towards the response (solution). The flow that it establishes is linear and resoluble and this does not fit neither with the cognitive processes that happen in the human reasoning not with a complex vision of the reality that, certainly, is not linear and not resoluble.

In the attempt of linearizing not linear problems across the Intelligence cycle, we find many of the lacks that the discipline raises as a function of utility but also we find the key to new approaches that experts and serious investigators as Clark, Schum and the one that writes, are developing and proposing.
