Porter’s Five Forces: A Complete Guide for Marketers in 2025

What are Porter’s Five Forces?

Porter’s Five Forces is a framework that analyzes the competitive pressures shaping an industry. Developed by Michael E. Porter in 1979, it helps leaders understand profitability by examining the forces of rivalry, new entrants, substitutes, suppliers, and buyers.

👉 You can see how this complements structured planning in my Pharma Marketing Strategies That Work article, where I explain how market dynamics influence launch success.


Why Porter’s Five Forces Still Matter in 2025

Even decades after its creation, the framework remains relevant. In 2025, industries are disrupted by digital platforms, global supply chains, and shifting customer expectations. The Five Forces provide clarity by highlighting where competition is strongest and where opportunities lie.

This model is not just for boardrooms. Marketers, product managers, and entrepreneurs can use it to guide decisions about pricing, positioning, partnerships, and growth.

The Five Forces Explained

1. Industry Rivalry: Competing for Market Share

This force examines how intense competition is among existing players. Factors include the number of competitors, the growth rate of the market, and the differentiation between products.

Example: In pharmaceuticals, rivalry is fierce in therapeutic areas like diabetes or oncology, where many firms compete with similar solutions.


2. Threat of New Entrants: Barriers to Entry

If new competitors can easily enter, profits decline. Barriers include patents, regulatory requirements, economies of scale, and brand loyalty.

Example: In pharma, regulatory approval and R&D costs create high barriers, but in digital health apps, entry is much easier.


3. Threat of Substitutes: Alternative Solutions

This force looks at the risk of customers switching to different solutions that meet the same need.

Example: A branded drug faces substitution from generics and biosimilars once patents expire. For marketers, substitutes require constant communication of value and differentiation.


4. Bargaining Power of Suppliers: Controlling Inputs

Suppliers with strong power can increase costs or reduce quality.

Example: In pharma, suppliers of active pharmaceutical ingredients (APIs) can wield significant power, especially if sourcing is limited to a few regions.

5. Bargaining Power of Buyers: Customer Influence

Buyers gain power when they can demand lower prices, better service, or higher quality.

Example: Large hospital networks, government health systems, and insurance providers often negotiate aggressively with pharmaceutical firms.
