This authoritative resource presents the underpinnings and applications in the emerging discipline of activity-based intelligence (ABI). This book defines, clarifies, and demystifies the tradecraft of ABI by providing concise definitions, clear examples, and thoughtful discussion. This book offers a comprehensive overview of ABI's principles and methods - developed by the U.S. Intelligence Community - and how they apply to intelligence analysis. Readers find insight into the evolution of intelligence in an era of dynamic change and diverse threats. Practicing professionals will gain an in-depth understanding of ABI and how it can be applied to real-world problems. "I heartily endorse this comprehensive, timely book. If you are tryingto quickly understand the paradigm shift over the past 40 years, youcould read several books, interview several diverse parties, investigate the underlying themes and technologies, or read Activity-Based Intelligence: Principles and Applications . The hours you invest in understanding the rich content contained herein will pay dividends to you for decades to come." Barry Barlow, Chief Technology Officer, Vencore "In this rich and informative book, Pat Biltgen and Steve Ryan document an emerging revolution in analytic tradecraft that is upending the intelligence community's traditional, linear, target-based, and often single-discipline(INT)-focused collection processes that are being overwhelmed by today's growing Big-Data glut. Activity-based Intelligence (ABI), as they deftly explain it, actually exploits Big Data by integrating - before exploitation - a wide swath of georeferenced data, both current and archived, from multiple INTs and other sources to extract from the "noise" intersections, patterns, relationships, and networks of intelligence value. The result for the 21st century intelligence consumers is a more complete, coherent,real-time picture of the threats and opportunities they face in an increasingly complex and dangerous world. The book, designed principally for intelligence professionals, reveals for the general public how the complicated business of intelligence is being revolutionized by a fertile collaboration between government and industry and by encouraging cross-discipline partnerships, including among engineers and analysts - as exemplified by the two talented authors whose passion for their work gave us this path-breaking introduction to ABI." John Gannon, former CIA Deputy Director for Intelligence and Chairman of the National Intelligence Council "As an imaging science engineer with a career in remote sensing, I have seen firsthand the importance of new insights that are gained as technology further empowers analytic rigor. This book benchmarks the opportunities for improved analysis and understanding by harnessing the power of location and time. Improved understanding of complex world events dictates that we advance innovation and tradecraft so we can fully leverage the nuances that make a difference." Jeffrey K. Harris, Former Director, National Reconnaissance Office --Jeffrey K. Harris Patrick Biltgen is the Analytics Family Offering Lead at Perspecta. Previously, he was a a senior principal systems engineer supporting the National Reconnaissance Office (NRO) and the senior mission engineer for BAE Systems' Intelligence Integration Directorate where he was the subject matter expert on activity-based intelligence (ABI) capabilities for the National Geospatial-Intelligence Agency (NGA). He received his Ph.D., M.S., and his B.S. in aerospace engineering from the Georgia Institute of Technology. Stephen Ryan is a senior manager in systems engineering in Northrop Grumman Corporation's Aerospace Systems sector, focused on advanced space systems development. He has previously served as a senior program manager, chief architect, and mission engineering manager across Northrop Grumman's advanced autonomy/artificial intelligence R&D, cyber, and intelligence, surveillance, and reconnaissance (ISR) businesses. He was previously a decorated intelligence analyst with the National Geospatial-Intelligence Agency (NGA), where he specialized in ABI and terrorism analysis, spending almost a year deployed to Afghanistan supporting counterterrorism and counterinsurgency operations. He is pursuing his M.S. in systems engineering from The Johns Hopkins University, received his M.A. in security studies from Georgetown University, and received his B.A. in international affairs from The George Washington University.
