SCAN for sensemaking and decision-making

Making sense in real-world uncertainty

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.

This is the first of a two-part series, showing the initial SCAN developments and usages up to 2014. The second part in the series, Updates on SCAN sensemaking: New developments for the SCAN model, describes further developments and usages from 2014 onwards.

This book includes about 35 posts and 55 images from the weblog. These posts are split into four groups:

  • SCAN: Core and Origins - describes the underlying concepts, structures and methods for the core SCAN framework.
  • SCAN: Sensemaking - explores how to use the SCAN frame to support sensemaking.
  • SCAN: Decision-making - illustrates how to use the SCAN frame to support real-world and real-time decision-making.
  • SCAN: Theory and Practice - presents the theory that underpins the SCAN framework, and practical examples of SCAN in use.
