# Five Forces Analysis (Porter's Five Forces)

Porter's Five Forces, developed by Michael Porter, is a framework for
analyzing the competitive intensity and attractiveness of an industry
— assessing five forces that together determine how much profit
potential an industry structurally allows, independent of any single
company's own strategy.

## The five forces

- **Competitive rivalry** — the intensity of competition among existing
  players (number of competitors, industry growth rate, differentiation
  level).
- **Threat of new entrants** — how easily new competitors can enter the
  market (barriers to entry: capital requirements, regulation, brand
  loyalty, [[strategic-scale-effects]]).
- **Bargaining power of suppliers** — how much leverage suppliers have
  to raise prices or reduce quality/availability.
- **Bargaining power of buyers** — how much leverage customers have to
  demand lower prices or better terms.
- **Threat of substitutes** — how easily customers can switch to a
  different product or service that meets the same underlying need.

## Why analyze the industry, not just the company

Unlike [[swot-analysis]] (which examines a specific organization) or
[[pestle-analysis]] (which examines the broad macro-environment),
Five Forces specifically examines the structure of the *industry*
itself — a useful complement, since even an excellent company can
struggle in a structurally unattractive industry (high rivalry, strong
buyer power, low barriers to entry), while a mediocre company can
thrive in a structurally favorable one.

## Using the analysis

A high-scoring force (strong pressure) generally signals lower
achievable industry profitability; the analysis helps identify which
specific force is the biggest constraint on an industry's
attractiveness, and can inform strategic moves that specifically
weaken that force (e.g. building [[strategic-moat-effects]] against new
entrants, or diversifying suppliers to reduce their bargaining power).

## Common pitfalls

- **Analyzing the company instead of the industry** — Five Forces is
  explicitly about industry structure; conflating it with a
  company-specific analysis (better suited to [[swot-analysis]]) misses
  its actual purpose.
- **Treating the five forces as equally important in every industry** —
  their relative weight varies significantly by industry; a strategic
  response should target whichever force is actually the binding
  constraint.
- **Doing a one-time analysis in a fast-changing industry** — industry
  structure can shift meaningfully (regulatory change, new technology
  enabling new entrants); the analysis benefits from periodic review,
  not a single static assessment.
