Porter's Five Forces

Porter's Five Forces, developed by Michael Porter, is a framework for analysing the structural competitiveness and profit potential of an industry. It focuses on external forces that shape margins, pricing power, and long term strategic positioning.

For technology-driven organisations, it provides a disciplined way to evaluate where advantage can be created or eroded beyond product execution alone.

1. Competitive Rivalry

Definition: The intensity of competition among existing players.

Key drivers:

• Number and relative size of competitors
• Rate of innovation and feature parity
• Switching costs
• Fixed cost structure and capital intensity
• Market growth rate

Technology lens:

• Rapid release cycles and open source ecosystems can compress differentiation.
• Cloud infrastructure reduces entry barriers, often increasing rivalry.
• Platform businesses may experience winner-takes-most dynamics.

High rivalry typically leads to pricing pressure, feature wars, and elevated customer acquisition costs.

2. Threat of New Entrants

Definition: How easily new competitors can enter the market.

Barriers to entry include:

• Capital requirements
• Network effects
• Regulatory constraints
• Brand trust
• Proprietary data or IP
• Economies of scale

Technology lens:

• API ecosystems and cloud-native tooling lower upfront costs.
• Distribution through app stores or marketplaces can both enable and constrain entry.
• Deep data moats and ML feedback loops can raise durable barriers.

Low barriers increase competition and limit long term margin expansion.

3. Bargaining Power of Suppliers

Definition: The ability of suppliers to influence pricing or terms.

In technology businesses, suppliers may include:

• Cloud infrastructure providers
• Data providers
• Key technology vendors
• Specialist engineering talent

Risk factors:

• Vendor lock-in
• Limited alternative providers
• High switching costs
• Dependence on proprietary platforms

For example, reliance on a small number of hyperscalers such as Amazon Web Services or Microsoft Azure can shift margin leverage upstream if architecture is not portable.

4. Bargaining Power of Buyers

Definition: The ability of customers to negotiate lower prices or demand more value.

Determinants:

• Customer concentration
• Availability of alternatives
• Switching costs
• Price sensitivity
• Procurement sophistication

Technology lens:

• Enterprise customers with formal procurement processes exert high pressure.
• Interoperability standards reduce switching costs.
• Subscription models increase transparency and comparability.

When buyers have strong leverage, differentiation and switching friction become critical strategic levers.

5. Threat of Substitutes

Definition: The availability of alternative solutions that meet the same underlying need.

Substitutes are not direct competitors; they solve the same problem differently.

Examples:

• Spreadsheets replacing specialised SaaS tools
• In-house engineering teams replacing third-party platforms
• Open source alternatives displacing commercial software

Substitutes cap pricing power and force continuous value articulation.

Using the Framework Strategically

The Five Forces model is not about forecasting disruption; it is about diagnosing structural profit constraints.

In practice:

• Identify which force most constrains margin expansion.
• Design technical architecture and product strategy to alter force dynamics.
• Create switching costs ethically through integration depth, data gravity, and workflow embedding.
• Invest in defensibility mechanisms such as network effects, ecosystem lock-in, or proprietary data assets.

The goal is not simply to compete better, but to reshape the structural forces in your favour.
