Peter Schwartz is one of the several leading scenario planners to emerge from Royal Dutch Shell, and is together with Arie de Geus (
The Living Company: Growth Learning and Longevity in Business) also one of the widely read and more easily approachable writers on the topic.
The art of the long view is definitely a good start for people not too familiar with scenario planning. It covers the topic from start to finish in an example filled but also surprisingly comprehensive fashion, given the length. It will not provide you with concrete solutions to highly specific scenario design or analysis questions in the way that Sterman's
Business Dynamics: Systems Thinking and Modeling for a Complex World with CD-ROM does for System Dynamics simulation (and scenario testing within the framework).
At the same time the author ensures that you get an overview of how to design compelling scenarios, on the appropriate number of them to the situation, on where and how to gather the appropriate data to populate the chosen scenarios, on how to compose a plot around them, how to interpret them or integrate them into a 'strategic conversation'... At the same time there are appendices with more information on the steps for developing the scenarios and a users guide to a strategic conversation, as well as a good bibliography and an index.
As mentioned, there are plenty of Schwartz' own, real world examples to demonstrate the concepts, which make the book read better, even if most of them are dated now (no less relevant for that). Some are truly fascinating in their foresight, while others played a bit differently (but then long term future gazing is not about point precise prediction); in all cases the effort of thinking about possible futures and what they mean for an individual, company, industry or country is definitely worthwhile, even if the specifically defined scenarios do not come to be exactly as laid out.
The 'remembering the future' aspect, allowing one to act very quickly and sustainably to rapid change simple due to prior preparation is an excellent practice, one many companies would do very well to adapt. The World in 2005 scenarios (the book itself was publshed in 1991) for instance are a fabulous demonstration of how the approach should be designed to work most effectively.
If you are new to the scenario planning world, this is definitely one of the books to go for. It is a good read even for people familiar with the approaches and long time scenario planners, as Schwartz also gives some good hints and arguments, on how to most compellingly present the pros and cons to outsiders to the scenario planning world.
And finally, even though it is a light advertorial for the author's own consulting company, this aspect largely falls to the wayside and does not have a detrimental effect on the enjoyment of the book, or its content.
