Crafting scenarios[ edit ] These combinations and permutations of fact and related social changes are called " scenarios ". The scenarios usually include plausible, but unexpectedly important situations and problems that exist in some small form in the present day. Any particular scenario is unlikely.

Some are based on subjective criteria and often amount to little more than wild guesses or wishful thinking. Others are based on measurable, historical quantitative data and are given more credence by outside parties, such as analysts and potential investors. While no forecasting tool can predict the future with complete certainty, they remain essential in estimating an organization's future prospects.

Using this technique, a group of field experts responds to a series of questionnaires. The experts are kept apart and unaware of each other.

The results of the first questionnaire are compiled, and a second questionnaire based on the results of the first is presented to the experts, who are then asked to reevaluate their responses to the first questionnaire.

This questioning, compilation and re-questioning continues until the researchers have a narrow range of opinions.

Scenario Writing In scenario writing, the forecaster generates different outcomes based on different starting criteria. The decision-maker then decides on the most likely outcome from the numerous scenarios presented. Scenario writing typically yields best, worst and middle options.

Subjective Approach Subjective forecasting allows forecasters to predict outcomes based on their subjective thoughts and feelings.

Subjective forecasting uses brainstorming sessions to generate ideas and to solve problems casually, free from criticism and peer pressure. These sessions are often used when time constraints prohibit objective forecasts.

Subjective forecasts are subject to biases and should be viewed skeptically by decision-makers. Time-Series Forecasting Time-series forecasting is a quantitative forecasting technique.

It measures data gathered over time to identify trends. The data may be taken over any interval: Trend, cyclical, seasonal and irregular components make up the time series.

The trend component refers to the data's gradual shifting over time. It is often shown as an upward- or downward-sloping line to represent increasing or decreasing trends, respectively.

Cyclical components lie above or below the trend line and repeat for a year or longer. The business cycle illustrates a cyclical component. Seasonal components are similar to cyclicals in their repetitive nature, but they occur in one-year periods. The annual increase in gas prices during the summer driving season and the corresponding decrease during the winter months is an example of a seasonal event.

Irregular components happen randomly and cannot be predicted.The description of the objectives of time series analysis are as follows: It is an important task in sales of forecasting and is the analysis of economic and industrial a package is only available when a package is loaded using library() function.

Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. those made at a range of two weeks or more, are impossible to definitively predict the state of the atmosphere, owing to the chaotic nature of the fluid dynamics equations involved.

In numerical models. Forecasting is a process of predicting or estimating the future based on past and present data. Forecasting provides information about the potential future events and .

Forecasting can be broadly considered as a method or a technique for estimating many future aspects of a business or other operation. Planning for the future is a critical aspect of managing any.

The following classification is a modification of the schema developed by Gordon over two decades ago: Genius forecasting - This method is based on a combination of intuition, insight, and luck. Psychics and crystal ball readers are the most extreme case of genius forecasting.
