概要	Environmental scanning for foresight is the systematic surveillance of an organization's external environment to collect, filter, and interpret the signals of change that feed a structured foresight process. In Joseph Voros's 2003 generic foresight process framework, scanning is the input stage — the activity that gathers the raw material on which all subsequent analysis depends — and the quality of that input bounds the quality of everything that follows. The method is deliberately broad and continuous: it casts a wide net across many channels, sifts the resulting flood for what is relevant, and interprets the survivors into emerging trends and issues. As codified in the Millennium Project's Futures Research Methodology, environmental scanning is the foundational discipline of strategic foresight, valued because foresight that rests on a narrow or stale view of the environment is foresight built on sand, however sophisticated the downstream methods.	STEEP structured scanning is a categorized horizon-scanning method that systematically sweeps the external environment for signals of change and sorts them into five domains — Social, Technological, Economic, Environmental, and Political. By imposing a fixed five-part taxonomy on an otherwise unbounded flood of information, STEEP forces analysts to look beyond the dimensions they habitually monitor and to give balanced attention to forces that might otherwise be ignored. The framework operationalizes the input or scanning stage of Joseph Voros's generic foresight process, providing the raw material of signals, trends, and emerging issues that later analysis interprets. As documented in the Millennium Project's Futures Research Methodology, categorized scanning is one of the foundational practices of strategic foresight, valued precisely because its discipline counteracts the natural tendency to over-monitor the familiar and under-monitor the surprising.
