Porter’s Competitive Forces Model
The best-known framework for analyzing competitiveness is Michael Porter’s competitive forces model (Porter, 1985).
![Page 14: Information Systems Concepts and Management](https://reader037.vdocument.in/reader037/viewer/2022102813/5467382cb4af9f0f1d8b4a0e/html5/thumbnails/14.jpg)
Porter’s Competitive Forces Model
![Page 15: Information Systems Concepts and Management](https://reader037.vdocument.in/reader037/viewer/2022102813/5467382cb4af9f0f1d8b4a0e/html5/thumbnails/15.jpg)
Porter’s Competitive Forces Model
Threat of entry of new competitors is high when it is easy to enter a market and low when significant barriers to entry exist.
A barrier to entry is a product or service feature that customers expect from organizations in a certain industry.
For most organizations, the Internet increases the threat that new competitors will enter a market.
![Page 16: Information Systems Concepts and Management](https://reader037.vdocument.in/reader037/viewer/2022102813/5467382cb4af9f0f1d8b4a0e/html5/thumbnails/16.jpg)
Porter’s Competitive Forces Model
The bargaining power of suppliers is high when buyers have few choices and low when buyers have many choices.
Internet impact is mixed. Buyers can find alternative suppliers and compare prices more easily, reducing power of suppliers.
On the other hand, as companies use the Internet to integrate their supply chains, suppliers can lock in customers.
![Page 17: Information Systems Concepts and Management](https://reader037.vdocument.in/reader037/viewer/2022102813/5467382cb4af9f0f1d8b4a0e/html5/thumbnails/17.jpg)
Porter’s Competitive Forces Model
The bargaining power of buyers is high when buyers have many choices and low when buyers have few choices.
Internet increases buyers’ access to information, increasing buyer power.
Internet reduces switching costs, which are the costs, in money and time, to buy elsewhere. This also increases buyer power.
![Page 18: Information Systems Concepts and Management](https://reader037.vdocument.in/reader037/viewer/2022102813/5467382cb4af9f0f1d8b4a0e/html5/thumbnails/18.jpg)
Porter’s Competitive Forces Model
The threat of substitute products or services is high when there are many substitutes for an organization’s products or services and low where there are few substitutes.
Information-based industries are in the greatest danger from this threat (e.g., music, books, software). The Internet can convey digital information quickly and efficiently.

Porter’s Competitive Forces Model
The rivalry among firms in an industry is high when there is fierce competition and low when there is not.

Porter’s Value Chain Model
This model identifies specific activities where organizations can use competitive strategies for greatest impact. Primary activities Support activities
