Origin

Harvard's Francis Aguilar proposed the ETPS framework, scanning economic, technical, political and social environments, in Scanning the Business Environment (1967). It later spread as PEST, STEP and similar acronyms.

The four factors

  • Political: government policy, regulation, taxation, trade policy, political stability
  • Economic: growth, interest and exchange rates, inflation, unemployment, incomes
  • Social: demographics, ageing, lifestyles, values, education, health awareness
  • Technological: new technology, R&D, automation, digital transformation, pace of change

Extensions

PESTEL (or PESTLE) adds environmental and legal factors, and STEEP emphasises ecology. Climate regulation and ESG expectations mean environmental factors are now often treated separately.

  1. Set the scope: industry, market and time frame.
  2. Collect relevant changes under each factor.
  3. Rank them by impact and likelihood.
  4. Translate them into opportunities and threats for strategy.

Results feed the opportunities and threats of a SWOT analysis and complement industry-level Five Forces analysis and scenario planning.

Limits

It easily becomes a static checklist that lists factors without their interactions or speed of change, so it needs regular updating and solid evidence.
