Scenario-building is designed to allow improved decision-making by allowing deep consideration of outcomes and their implications. A scenario is a tool used during requirements analysis to describe a specific use of a proposed system. Scenarios capture the system, as viewed from the outside
A number of criticisms have been leveled against the use of worst-case scenarios. [1] In some cases, a conceivable worst-case scenario within a field may be so far beyond the capacity of participants to deal with that it is not worth the effort to develop or explore such a scenario; where this is possible, it is "important to evaluate whether the development of a worst-case scenario is ...
Full student loan forgiveness may not be the most likely scenario, according to many experts. “Somewhere in between these two scenarios is the most likely scenario of some, but not all, of their ...
An economic impact analysis attempts to measure or estimate the change in economic activity in a specified region, caused by a specific business, organization, policy, program, project, activity, or other economic event. [2] The study region can be a neighborhood, town, city, county, statistical area, state, country, continent, or the entire globe.
In a 1994 study, 37 psychology students were asked to estimate how long it would take to finish their senior theses.The average estimate was 33.9 days. They also estimated how long it would take "if everything went as well as it possibly could" (averaging 27.4 days) and "if everything went as poorly as it possibly could" (averaging 48.6 days).
A what if chart (Whif chart, WHIF analysis, etc.) is a visual tool for modeling the outcome of a combination of different factors.The table can represent actual results or predicted outcome based on combinations of parameters.
The scenario approach or scenario optimization approach is a technique for obtaining solutions to robust optimization and chance-constrained optimization problems based on a sample of the constraints. It also relates to inductive reasoning in modeling and decision-making.
There are ways of using probabilities that are definitely not Monte Carlo simulations – for example, deterministic modeling using single-point estimates. Each uncertain variable within a model is assigned a "best guess" estimate. Scenarios (such as best, worst, or most likely case) for each input variable are chosen and the results recorded. [61]
