This chapter presents the reasons behind the differences in the approaches of different terrorist groups to innovation. It focuses on making some observations about the general trends in tactical and technological innovation in terrorist campaigns. The chapter concerns on the factors and conditions responsible for the differences between innovative tendencies of different terrorist organizations. It identifies implications for the future, especially in relation to innovative patterns of al-Qaeda and its affiliates. The chapter explains that the terrorist innovation is a highly complex process, and only few of the individual variables proposed have demonstrates applicability in terms of being able to universally explain what distinguishes an innovative group from a conservative one. The durability of an organization was hypothesized to be another key factor, based on the simple logic that organizations that exist longer have more time to progress in terms of their motivation to innovate.
