The third step is to develop the scenarios that describe different plausible futures based on the key drivers. You can use different methods, such as brainstorming, matrix, or morphological analysis, to generate and organize your scenarios. You should aim for a set of scenarios that are diverse, relevant, challenging, and consistent. For example, you could develop four scenarios for the COVID-19 pandemic scenario based on two key drivers: the virus transmission rate and the vaccine availability. These scenarios could be: rapid recovery, slow recovery, chronic crisis, and new normal.
