概要	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 scenario method constructs a small set of internally consistent, plausible stories about how the future might unfold, built from the key driving forces and critical uncertainties facing a decision. Rather than forecasting one expected future, it deliberately develops several contrasting futures so that strategies can be tested against a range of possibilities and decision-makers can rehearse responses to what might otherwise be surprises.
