Presentation Tips: Porter 5 Forces Analysis
I have personally been using the Porter 5 Forces framework to do industry analysis for over ten years. The Porter 5 Forces framework was developed by Michael E. Porter of Harvard Business School in 1979. Porter 5 Forces analysis is an excellent framework that could help managers, entrepreneurs and investors to evaluate whether a business is operating in a profitable industry. From the results of this analysis, strategies could be formulated to help companies identify opportunities and avoid threats.
Here is a Porter 5 Forces framework:

Approach written by Charles W. L. Hill and Gareth R. Jones
Each force in this framework could be categorized as strong, medium, or weak. Strong forces are perceived as threats to the enterprise. Strong forces have strong bargaining power thus limit the enterprise’s ability to increase price or lower cost. On the other hand, weak forces are perceived as opportunities. Weak forces have low bargaining power thus the enterprise could increase price or lower cost to sustain more profit.
Here is a list of the five forces. Answer the questions on the right-hand column and you will be able identify whether the forces should be categorized as opportunities or threats.
The five forces in this framework include the followings:
| Potential Competitors/ Barrier of Entry (Companies currently not competing in the industry but have the necessary resources to do so) |
|
| Threat of Substitutes (Products in another industry that satisfy similar needs) |
|
| Intensity of rivalry among established firms (Direct competitors competing for market share) |
|
| Bargaining power of buyers (Customers) |
|
| Bargaining power of suppliers |
|
After analyzing each force individually, the next step is to interrupt the results of this framework as a whole. For example, if you have strong suppliers that are raising their prices, are you able to shift the cost to your customers? Do you have a weak buyer? You can also formulate strategies according to the results to change your situation. For instance, you can integrate backward and stop buying from your suppliers. You can also launch your own retailers and sell your own goods through your own distribution channels. Depending on your own situation, try to formulate the right strategies to increase your bargaining power against the five forces.
