What are the different methods used for technological forecasting?

Technological forecasting is the process of predicting future technological developments and advances. There are several methods used for technological forecasting, each with its own advantages and limitations. These methods include trend analysis, expert opinion, Delphi method, scenario analysis, patent analysis, and technology roadmapping. Trend analysis involves examining historical data and identifying patterns and trends that can help predict future technological developments. Expert opinion involves consulting with subject matter experts who have in-depth knowledge and experience in a specific field. The Delphi method involves collecting and analyzing feedback from a panel of experts anonymously to reach a consensus on future technological developments. Scenario analysis involves creating different scenarios based on different assumptions and examining the impact of each scenario on technological development. Patent analysis involves studying the number and type of patents filed in a particular field to assess future technological developments. Technology roadmapping involves visualizing the future trajectory of technology by mapping out current and future technological capabilities and identifying gaps in between. Utilizing a combination of these methods can provide a comprehensive and accurate picture of future technological developments.
