The magic of Mr. Porter

Companies operate in a wider perspective. They are required to perform strategic decisions ate every stage of the process of operations. The context of the competitive strategy of any company is to maintain a symbiosis between its internal and external environment. However, the external environment is dynamic and changes with technology. To align the internal structure of the company with its environment, it becomes imperative for the company to analyse its environment and to do that we have various models in place. Porter's five forces model is one such model wherein we can do an industry wide analysis of the various growth drivers, the level of competition and other factors regarding demand and supply.
          
Porter’s 5 forces model is one of the most recognized framework for the analysis of business strategy. Porter, the guru of modern day business strategy, used theoretical frameworks derived from Industrial Organization (IO) economics to derive five forces which determine the competitive intensity and therefore attractiveness of a market. This theoretical framework, based on 5 forces, describes the attributes of an attractive industry and thus suggests when opportunities will be greater, and threats less, in these of industries.
Attractiveness in this context refers to the overall industry profitability and also reflects upon the profitability of the firm under analysis. An “unattractive” industry is one where the combination of forces acts to drive down overall profitability. A very unattractive industry would be one approaching “pure competition”, from the perspective of pure industrial economics theory.

This model comprises of an analysis dependent on 4 entities external to the firm and the fifth force: the Industry structure. These forces are defined as follows:

1. The threat of the entry of new competitors
2. The intensity of competitive rivalry
3. The threat of substitute products or services
4. The bargaining power of customers
5. The bargaining power of suppliers

A detailed explanation of what these forces comprise of is provided in the diagrammatic representation of these 5 forces next.



Now, let us go about explaining each and every force in a certain detail.

Threat of New Entrants

New entrants to an industry can raise the level of competition, thereby reducing its attractiveness. The threat of new entrants largely depends on the barriers to entry. High entry barriers exist in some industries (e.g. shipbuilding) whereas other industries are very easy to enter (e.g. estate agency, restaurants). Key barriers to entry include
- Economies of scale
- Capital / investment requirements
- Customer switching costs
- Access to industry distribution channels
- The likelihood of retaliation from existing industry players.

Threat of Substitutes

The presence of substitute products can lower industry attractiveness and profitability because they limit price levels. The threat of substitute products depends on:

- Buyers' willingness to substitute
- The relative price and performance of substitutes
- The costs of switching to substitutes

Bargaining Power of Suppliers

Suppliers are the businesses that supply materials & other products into the industry.

The cost of items bought from suppliers (e.g. raw materials, components) can have a significant impact on a company's profitability. If suppliers have high bargaining power over a company, then in theory the company's industry is less attractive. The bargaining power of suppliers will be high when:

- There are many buyers and few dominant suppliers
- There are undifferentiated, highly valued products
- Suppliers threaten to integrate forward into the industry (e.g. brand manufacturers threatening to set up their own retail outlets)
- Buyers do not threaten to integrate backwards into supply
- The industry is not a key customer group to the suppliers

Bargaining Power of Buyers

Buyers are the people / organisations who create demand in an industry

The bargaining power of buyers is greater when
- There are few dominant buyers and many sellers in the industry
- Products are standardised
- Buyers threaten to integrate backward into the industry
- Suppliers do not threaten to integrate forward into the buyer's industry
- The industry is not a key supplying group for buyers

Intensity of Rivalry

The intensity of rivalry between competitors in an industry will depend on:

- The structure of competition - for example, rivalry is more intense where there are many small or equally sized competitors; rivalry is less when an industry has a clear market leader
- The structure of industry costs - for example, industries with high fixed costs encourage competitors to fill unused capacity by price cutting
- Degree of differentiation - industries where products are commodities (e.g. steel, coal) have greater rivalry; industries where competitors can differentiate their products have less rivalry
- Switching costs - rivalry is reduced where buyers have high switching costs - i.e. there is a significant cost associated with the decision to buy a product from an alternative supplier
- Strategic objectives - when competitors are pursuing aggressive growth strategies, rivalry is more intense. Where competitors are "milking" profits in a mature industry, the degree of rivalry is less
- Exit barriers - when barriers to leaving an industry are high (e.g. the cost of closing down factories) - then competitors tend to exhibit greater rivalry.

Before we draw the curtains, let us see what the sorcerer himself has to say on this:

Brilliant, isn't it? That's all for now. Until next time.
