Hardin Tibbs' paper, Making the Future Visible: Psychology, Scenarios and Strategy, is a must-read paper for anyone interested in using scenario planning. Tibbs writes about the future as a strategic landscape and uses this graphic to explain it (reproduced with the author's permission). The "star" in Hardin's image is the long term guiding purpose for an organisation, the reason why organisations exist, and the pull of the future that keeps us going when the chessboard gets difficult to navigate.
The chessboard is the land of scenarios, where we develop strategies to move us closer to the star. The key in futures work is to clearly define your star, and keep your eye on that as you move through the chessboard of day-to-day life.
