An examination of future scenarios using historical analogy

The quality of scenario planning activities can be difficult to assess, as one cannot know how likely any projected future scenario is. Here, we introduce one approach for gaining greater confidence. Historical analogy provides the means for achieving this, whereby the model upon which scenarios are constructed is analysed in terms of how well it predicts and establishes links with recent historical environments. We apply this approach to a previously developed scenario tree, constructed using the field anomaly relaxation method, as a case study to indicate how historical analogy can be used to assess and enhance the model from which the scenarios are constructed.
