The process of identifying a range of plausible scenarios based on different assumptions (e.g. an expected case, a worst case, and a best case, scenario), and assessing the variability of outcomes based on changes in the scenario. This is especially important in uncertainty, i.e. when the variables are not completely within, or are outside, the entity’s control (e.g. climate change).
