As criminologist he developed the triangle to explain criminal behavior, but as sociologist he did much more, he created a simple model to explain human behavior in groups. Motivation, rationalization and opportunity define which conditions must be given to provoke non-conformal behavior of single participants inside a group. On the other hand the triangle identifies which areas to focus on to prevent possible wrong-doings and implement adequate counter-measures.
Especially in times of business pressures and limited budgets, the book is an ideal starting point to elaborate your own Ethics & Compliance system or adapt an existing one.
