ABSTRACT
This chapter presents the fundamental theoretical ideas underlying all intelligence work, whether in the public or private sector and demonstrates the knowledge-data hierarchy and explain how data, information, and intelligence are different concepts. It introduces the key roles and responsibilities within the intelligence team. One of the most important points for any intelligence practitioner to understand is that there is a very real difference between information and intelligence. The intelligence cycle is represented in various forms today, and is subject to intense debate, although every intelligence function in existence almost certainly reflects its underlying logic. The intelligence manager has overall responsibility for coordination of the team and output of the product. This role is therefore central to producing high-quality material. While public-sector-funded intelligence organizations most certainly worry about budgetary issues, the prospect of continually fighting for survival is not terribly urgent.
