概要	PESTEL macro-environmental scanning is a structured audit of the forces in an organization's wider operating environment, organized into six factor classes: Political, Economic, Social, Technological, Environmental, and Legal. Unlike open-ended horizon scanning, PESTEL is typically run as a deliberate audit that enumerates the specific drivers in each class, gathers evidence for them, and assesses their likely impact and direction so that the findings can feed directly into strategy formulation. It operationalizes the input stage of Joseph Voros's generic foresight process while retaining its roots in strategic management, where the explicit inclusion of a Legal dimension makes it well suited to regulated industries and compliance-sensitive decisions. As catalogued in the Millennium Project's Futures Research Methodology, macro-environmental scanning of this kind is a foundational discipline that grounds long-range strategy in a systematic reading of external forces rather than in the assumptions of the moment.	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.
