| There are many descriptions of scenario planning methods, with the biggest difference being whether the scenarios are designed to be exploratory (multiple alternative scenarios for different possible futures), or normative (designing a desired scenario, then figuring out what needs to be done in order to get there). When working with normative scenarios the most important task is 'backcasting' or 'retrocasting' as we prefer to call it (see chapter about this lower on this page). With exploratory scenarios a lot of the time is spent on creating the elements of the scenario based on the present of the internal and external environment, as well as forces that can influence change in both. Most scenario methods revolve around approximately the same phases: (1) delineating the space/issue/question (2) identifying elements of the scenario (factors, drivers, trends, measures, actors, events...) 3) selecting a reasonable amount of elements 4) projecting the elements in the given future in the form of multiple scenarios and 5) using scenarios to (re)design decisions, strategies and actions in the present. There are many different variations of scenario building flow. We list a few below: | There are many descriptions of scenario planning methods, with the biggest difference being whether the scenarios are designed to be exploratory (multiple alternative scenarios for different possible futures), or normative (designing a desired scenario, then figuring out what needs to be done in order to get there).

| | "Based on our review of the literature, we have discovered eight general categories (types) of scenario techniques with two to three variations for each type, resulting in more than two dozen techniques overall. There are, of course, variations of the variations. |
| | |
| | - Judgment (genius forecasting, visualization, role playing, Coates and Jarratt) |
| | - Baseline/expected (trend extrapolation, Manoa, systems scenarios, trend impact analysis) |
| | - Elaboration of fixed scenarios (incasting, SRI) |
| | - Event sequences (probability trees, sociovision, divergence mapping) |
| | - Backcasting (horizon mission methodology, Impact of Future Technologies, future mapping) |
| | - Dimensions of uncertainty (morphological analysis, field anomaly relaxation, GBN, MORPHOL, OS/SE) |
| | - Cross-impact analysis (SMIC PROF-EXPERT, IFS) |
| | - Modeling (trend impact analysis, sensitivity analysis, dynamic scenarios) |

| Joseph Coates wrote "Today the question of what scenarios are is unclear except with regard to one point-they have become extremely popular. Many people see scenarios as forecasts of some future condition while others disavow that their scenarios are forecasts. Yet looking at scenarios that do not come labeled as forecasts or non-forecasts. It is difficult to tell them apart. The purpose of the scenario is at a meta level, since the scenario usually does not speak for itself in terms of its purpose."
