When creating alternative scenarios, there are a few steps and tips to keep in mind. Firstly, it is important to define the scope and purpose of the forecasting exercise. Consider the main question or issue to explore, the time horizon, and the level of detail needed. Secondly, gather relevant data and information. Analyze current trends and drivers that affect the topic, as well as the sources and quality of the data. Validate and verify the data to ensure accuracy. Thirdly, identify the key uncertainties and variables. These are the factors or events that have a high impact and a high uncertainty on the topic. Categorize them into different dimensions or axes. Fourthly, create a scenario matrix. This matrix should define four or more quadrants, each representing a different combination of possible outcomes. Give each quadrant a descriptive and catchy name. Fifthly, develop the scenario narratives. For each quadrant, write a story that explains how and why the future evolved in that way. Use intuition and creativity to fill in the gaps and add details, such as actors, actions, consequences, and emotions. Utilize <code>if-then</code> statements to show the causal logic and the branching points of the scenarios. Lastly, analyze and compare the scenarios. Look for common themes and differences among the scenarios. Consider the implications and challenges for the topic. Use the scenarios to inform decisions and actions.
