Technological Forecasting—An Overview

Within the past decade, the set of techniques used by technological forecasters has expanded considerably. While the old standbys such as trend extrapolation are still in wide use, some new techniques are also beginning to see wide use. In addition, there are some new techniques which have considerable promise, but which have not yet seen wide use. Finally, there are some techniques which have not yet fulfilled their original promise. Examples of each of these categories are discussed in the paper.
