Introduction
Environmental scanning is the systematic process of collecting, analyzing, and interpreting information about external trends, drivers, and emerging issues that could impact an organization, industry, or society. The goal is to detect early signals of change (technological, social, political, economic, environmental, or legal) that may influence strategic decisions.
See the PESTLE Drivers of Change article.
In foresight work, it is often referred to as horizon scanning or trend monitoring and forms the bedrock of futures thinking. It helps practitioners move beyond assumptions and short-term noise to identify long-term patterns shaping the future.
Francis J. Aguilar introduced four modes of scanning: undirected viewing, conditioned viewing, informal search, and formal search, each describing how organizations gather information about their environments.
What It Looks Like
Using environmental scanning involves:
- Systematically reviewing a wide variety of information sources, academic journals, media, social platforms, patent databases, scientific publications, think tank reports, and more.
- Recording weak signals and emerging issues in a database or spreadsheet.
- Tagging each finding with categories (like PESTLE) and descriptors such as time horizon, impact level, or uncertainty.
- Discussing and interpreting the signals in a team setting to identify clusters and patterns.
- Synthesizing insights into concise briefings or trend cards that feed into tools like scenario planning, strategy development, or visioning.
In a futures workshop, this often looks like a wall of post-its or a digital board filled with snippets of news articles, quotes, and images, each representing a signal or driver of change.
Examples
A strong example of environmental scanning in action is Shell’s Scenarios Team in the 1970s.
Shell analysts conducted wide-ranging environmental scans to detect shifts in global energy markets, geopolitics, and technology.
Their early recognition of instability in oil-producing regions allowed Shell to prepare scenarios that anticipated the 1973 oil crisis—giving the company a decisive strategic advantage over competitors.
Another example is the World Economic Forum’s Global Risks Report, which compiles signals from across domains to map global risk interconnections annually. This is a large-scale, institutionalised form of environmental scanning.
How and When It Is Used
Environmental scanning is the first stage in nearly every foresight or strategic planning process. It is used:
- Before scenario planning, to build the evidence base for key uncertainties.
- Before visioning or backcasting, to ensure assumptions about the future are grounded in observable trends.
- Continuously, as an ongoing intelligence function within organisations, not just a one-off research activity.
It is particularly valuable in:
- Strategic foresight units, innovation labs, think tanks, and R&D departments.
- Governments and international organisations monitoring global trends (e.g., OECD, UNDP, EU).
- Corporations and NGOs tracking technological, social, and environmental change.
Notable Uses
- Wild Cards and Weak Signals: Some futurists use environmental scanning to deliberately look for “outliers” or fringe developments, those that seem irrelevant now but could have major impacts later (e.g., early AI experiments in the 1980s).
- Crowdsourced Scanning: Platforms like Shaping Tomorrow and Futures Platform allow users worldwide to contribute signals, democratising scanning.
- Art and Culture Scanning: Some practitioners include cultural artefacts (films, music, memes, speculative fiction) as signals of social undercurrents or emerging values.
- AI-Augmented Scanning: Increasingly, AI tools are used to scrape, categorise, and visualise vast amounts of horizon data in real time.
- Reverse Scanning: Some teams start with a preferred future vision and scan backwards to identify current weak signals that might lead toward (or threaten) that future.
Origin
The concept originated in the strategic management and organisational theory fields of the 1960s and 1970s.
The term “environmental scanning” was first popularised by Francis J. Aguilar in his 1967 book Scanning the Business Environment (Harvard Business School).
In the foresight community, environmental scanning was expanded by futurists such as Peter Bishop, Wendy Schultz, and Richard Slaughter, who used it as a core input for futures studies and scenario planning.
The practice later evolved through work by Igor Ansoff, Henry Mintzberg, and others who integrated it into strategic planning and systems thinking.
