สรุป	Horizon scanning is the systematic examination of information to detect early signs of potentially important developments—weak signals, emerging issues, and wild cards—before they become obvious or fully formed. By surveying a wide range of sources at the edge of current attention, it gives decision-makers advance warning of opportunities and threats and supplies the raw material for foresight, scenario building, and anticipatory policy.	The technology Delphi is a large-scale, multi-round expert survey used to forecast the timing, importance, and feasibility of future technological developments. Built on the classic Delphi principles of anonymity, iteration, controlled feedback, and statistical aggregation, it elicits judgements from hundreds or thousands of experts on a structured list of technology statements and converges them, round by round, into a collective forecast that informs national and organisational science and technology priorities.
