Pre-Thinking vs Scenario Planning

In Innovation Excellence:   Forecasting is a long term interest.  I have taught it and implemented it in corporate systems.   There are many styles, from using numerical modeling, to means of generally mapping the broad possibilities and preparing for many of them.  The linked article suggests the use of 'pre-thinking' vs the well known scenario planning method.   Interesting, worth thinking about, but not much different except in the philosophy of determining the scenarios.   I think there is value in integrating scenario analysis and quantitative systems, which combines the best aspects of both methods.
