About the Book

This anthology from the Tetradian weblog covers the SCAN model-type and its related uses and modelling methods. SCAN is used to guide sensemaking and decision-making in contexts with varying levels of complexity, uncertainty and uniqueness.

The initial anthology in this set was published in 2014. This 2022 update adds around 35 posts and 125 images, representing new material on SCAN published on the weblog since 2014. These posts are split into three groups:

  • SCAN: Core Extensions - provides new concepts, insights and methods for the core SCAN framework.
  • SCAN: Complexity - explores further work on theory and practice on complexity, and how this relates with the SCAN framework.
  • SCAN: Usage-Examples - presents a range of real-world examples where the SCAN framework helps to explain a concept or concern and is put to practical use.
