This technical report has two purposes. One purpose is to present an end product of a multi-year research investigation into the cognitive skills involved in performing intelligence analysis. The product is a "Handbook for Strategic Intelligence Analysis" developed for the United States Army Intelligence and Threat Analysis Center (ITAC). The other purpose of this report is to summarize the course of development of the handbook so that users and training developers may better understand the Army needs that prompted the handbook development and the research on which it is based. The report begins with a discussion of the background research into the thinking processes of intelligence analysis and of the resulting descriptive cognitive model of analysis. It then briefly describes the training products that were developed based on the research findings, including the handbook. Finally, the handbook itself is provided in an appendix which is 90% of the document. The handbook is being used at ITAC as part of their training program for new strategic analysts and as a general reference guide. (PN)
