Scans Political, Economic, Social, Technological, Legal, and Environmental factors.

PESTLE Analysis is a strategic environmental-scanning tool that organizes external macro-environmental factors into six categories: Political (government policy, political stability), Economic (growth, inflation, exchange rates, interest rates), Social (demographics, culture, attitudes), Technological (R&D activity, automation, technology incentives), Legal (employment, consumer protection, antitrust), and Environmental (weather, climate, ecology). Earlier variants — PEST (four factors), PESTEL (six), STEEP, STEEPLE (adding Ethical) — represent successive expansions. The tool is generally attributed to Francis Aguilar's Scanning the Business Environment (1967), where ETPS (Economic, Technical, Political, Social) was the original framing. PESTLE complements SWOT (which is firm-centric) by ensuring the external scan is structured rather than ad hoc, and is widely used in strategic planning, market entry analysis, and macroeconomic risk assessment.

Common criticisms

Like SWOT, generates lists rather than analysis without prioritization or causal linkage
categorization of any specific factor across categories is often arbitrary (e.g., is a carbon tax Political, Economic, Legal, or Environmental?)
static snapshot of fast-moving environments
doesn't address inter-factor dynamics
can become checkbox compliance rather than genuine scanning
many practitioners use it as a brainstorming starter without rigorous research backing
environmental scans are only as good as the underlying research, which the framework doesn't compel.
