In the past, new concepts have largely stemmed from the use of intuitive techniques by original thinkers. These approaches, though still useful, are now reinforced by more powerful, formal, and systematic, methods of examining the possible patterns for the future.

The results of the forecasting process may then be assessed and evaluated using further methods of operational research such as cost effectiveness analysis.
