Scenario thinking is a strategic planning method that organisations use to make flexible long-term plans. Recent discussions of this method offered by the Foresight Horizon Scanning Centre (2009) define scenario thinking (they refer to it as scenario planning) as ‘a futures technique for medium to long-term strategic analysis and planning used to develop policies and strategies that are robust, resilient, flexible and innovative’. This five day help desk review provides an overview of academic, policy and practitioner literature that examines scenario thinking. Whilst there exists’ a broad consensus that scenario thinking can play a useful role in developing organisational strategies, there is debate as to which scenario thinking approach is most appropriate, and how to avoid a number of common pitfalls associated with the use of scenarios. It is important to highlight that the term ‘scenarios’ has a broad application, receiving different levels of attention from various academic, policy and practitioner communities.
