Porter's Five Forces is a strategic framework developed by:

Michael Porter

It helps businesses understand:

How Competitive Is An Industry?
          ↓
How Easy Is It To Make Profit?

🧠 Simple Real-Life Analogy

Imagine you open a restaurant.

Before starting, you need to know:

How Many Competitors Exist?
Can New Restaurants Open Easily?
Can Customers Switch Easily?
Can Suppliers Increase Prices?
Are Alternative Food Options Available?

These factors determine whether your restaurant can earn good profits.

🚀 The Core Idea

Porter's Five Forces helps answer:

"Why are some industries highly profitable while others struggle to make money?"

Example:

Luxury Software Industry
        ↓
Often High Profit

Airline Industry
        ↓
Often Low Profit

The difference comes from industry forces.

The Industry Around Your Company

The framework helps answer:

What Risks Exist?
Where Should We Focus Strategically?

The essence of Porter's Five Forces is:

Competitive Rivalry
        +
Threat of New Entrants
        +
Buyer Power
        +
Supplier Power
        +
Threat of Substitutes

Industry Profitability

The stronger these forces become, the harder it is to earn sustainable profits. The weaker these forces become, the more attractive and profitable the industry tends to be.
