Porter forces
Porter’s Five Forces analysis is a framework that helps analyzing the level of competition within a certain
industry. It is especially useful when starting a new business or when entering a new industry sector.
According to this framework, competitiveness does not only come from competitors. Rather, the state
of competition in an industry depends on five basic forces: threat of new entrants, bargaining power of
suppliers, bargaining power of buyers, threat of substitute products or services, and existing industry
rivalry. The collective strength of these forces determines the profit potential of an industry and thus
its attractiveness. If the five forces are intense (e.g. airline industry), almost no company in the industry
earns attractive returns on investments. If the forces are mild however (e.g. softdrink industry), there
is room for higher returns. Each force will be elaborated on below with the aid of examples from the
airline industry to illustrate the usage.
Figure 1: Five Forces Model
Threat of new entrants
New entrants in an industry bring new capacity and the desire to gain market share. The seriousness of
the threat depends on the barriers to enter a certain industry. The higher these barriers to entry, the
smaller the threat for existing players. Examples of barriers to entry are the need for economies of
scale, high customer loyalty for existing brands, large capital requirements (e.g. large investments in
marketing or R&D), the need for cumulative experience, government policies, and limited access to
distribution channels. More barriers can be found in the table below.
Example
The threat of new entrants in the airline industry can be considered as low to medium. It takes quite
some upfront investments to start an airline company (e.g. purchasing aircrafts). Moreover, new
entrants need licenses, insurances, distribution channels and other qualifications that are not easy to
obtain when you are new to the industry (e.g. access to flight routes). Furthermore, it can be expected
that existing players have built up a large base of experience over the years to cut costs and increase
service levels. A new entrant is likely to not have this kind of expertise, therefore creating a competitive
disadvantage right from the start. However, due to the liberalization of market access and the
availability of leasing options and external finance from banks, investors, and aircraft manufacturers,
new doors are opening for potential entrants. Even though it doesn’t sound very attractive for
companies to enter the airline industry, it is NOT impossible. Many low-cost carriers like Southwest
,Airlines, RyanAir and EasyJet have successfully entered the industry over the years by introducing
innovative cost-cutting business models, thereby shaking up original players like American Airlines,
Delta Air Lines and KLM.

Bargaining power of suppliers
This force analyzes how much power and control a company’s supplier (also known as the market of
inputs) has over the potential to raise its prices or to reduce the quality of purchased goods or services,
which in turn would lower an industry’s profitability potential. The concentration of suppliers and the
availability of substitute suppliers are important factors in determining supplier power. The fewer there
are, the more power they have. Businesses are in a better position when there are a multitude of
suppliers. Sources of supplier power also include the switching costs of companies in the industry, the
presence of available substitutes, the strength of their distribution channels and the uniqueness or level
of differentiation in the product or service the supplier is delivering.
Example
The bargaining power of suppliers in the airline industry can be considered very high. When looking at
the major inputs that airline companies need, we see that they are especially dependent on fuel and
aircrafts. These inputs however are very much affected by the external environment over which the
airline companies themselves have little control. The price of aviation fuel is subject to the fluctuations
in the global market for oil, which can change wildly because of geopolitical and other factors. In terms
of aircrafts for example, only two major suppliers exist: Boeing and Airbus. Boeing and Airbus therefore
have substantial bargaining power on the prices they charge.
Bargaining power of buyers
The bargaining power of buyers is also described as the market of outputs. This force analyzes to what
extent the customers are able to put the company under pressure, which also affects the customer’s
sensitivity to price changes. The customers have a lot of power when there aren’t many of them and
when the customers have many alternatives to buy from. Moreover, it should be easy for them to
switch from one company to another. Buying power is low however when customers purchase products
in small amounts, act independently and when the seller’s product is very different from any of its
competitors. The internet has allowed customers to become more informed and therefore more
empowered. Customers can easily compare prices online, get information about a wide variety of
products and get access to offers from other companies instantly. Companies can take measures to
reduce buyer power by for example implementing loyalty programs or by differentiating their products
and services.
Example
Bargaining power of buyers in the airline industry is high. Customers are able to check prices of different
airline companies fast through the many online price comparisons websites such as Skyscanner and
Expedia. In addition, there aren’t any switching costs involved in the process. Customers nowadays are
likely to fly with different carriers to and from their destination if that would lower the costs. Brand
loyalty therefore doesn’t seem to be that high. Some airline companies are trying to change this with
frequent flyer programs aimed at rewarding customers that come back to them from time to time.
Threat of substitute products
The existence of products outside of the realm of the common product boundaries increases the
propensity of customers to switch to alternatives. In order to discover these alternatives one should
look beyond similar products that are branded differently by competitors. Instead, every product that
serves a similar need for customers should be taken into account. Energy drink like Redbull for instance
is usually not considered a competitor of coffee brands such as Nespresso or Starbucks. However, since
both coffee and energy drink fulfill a similar need (i.e. staying awake/getting energy), customers might
be willing to switch from one to another if they feel that prices increase too much in either coffee or
,energy drinks. This will ultimately affect an industry’s profitability and should therefore also be taken
into account when evaluating the industry’s attractiveness.
Example
In terms of the airline industry, it can be said that the general need of its customers is traveling. It may
be clear that there are many alternatives for traveling besides going by airplane. Depending on the
urgency and distance, customers could take the train or go by car. Especially in Asia, more and more
people make use of highspeed trains such as Bullet Trains and Maglev Trains. Furthermore, the airline
industry might get some serious future competition from Elon Musk’s Hyperloop concept in which
passengers will be traveling in capsules through a vacuum tube reaching speed limits of 1200 km/h.
Taken this altogether, the threat of substitutes in the airline industry can be considered at least medium
to high.
Rivalry among existing competitors
This last force of the Porter’s Five Forces examines how intense the current competition is in the
marketplace, which is determined by the number of existing competitors and what each competitor is
capable of doing. Rivalry is high when there are a lot of competitors that are roughly equal in size and
power, when the industry is growing slowly and when consumers can easily switch to a competitors
offering for little cost. A good indicator of competitive rivalry is the concentration ratio of an
industry. The lower this ration, the more intense rivalry will probably be. When rivalry is high,
competitors are likely to actively engage in advertising and price wars, which can hurt a business’s
bottom line. In addition, rivalry will be more intense when barriers to exit are high, forcing companies
to remain in the industry even though profit margins are declining. These barriers to exit can for
example be long-term loan agreements and high fixed costs.
Example
When looking at the airline industry in the United States, we see that the industry is extremely
competitive because of a number of reasons which include the entry of low cost carriers, the tight
regulation of the industry wherein safety become paramount leading to high fixed costs and high
barriers to exit, and the fact that the industry is very stagnant in terms of growth at the moment. The
switching costs for customers are also very low and many players in the industry are similar in size (see
graph below) leading to extra fierce competition between those firms. Taken altogether, it can be said
that rivalry among existing competitors in the airline industry is high.

, By looking at each competitive force individually, you are able to roughly map out the focal industry
and its attractiveness. Note that industries might differ in terms of attractiveness depending on the
country you are looking at. Government policies are for example likely to be different in each country
and also the amount of suppliers and buyers might vary from nation to nation. Porter’s Five Forces is a
good starting point to evaluate an industry but should not be used in isolation. You could for example
combine it with a Value Chain Analysisor through the VRIO Framework in order to get a better sense of
where your company’s competitive advantage is coming from and to better position your company
between the rivals. Moreover, Porter’s Five Forces is often combined with the PESTEL analysis to give
a good overview of the organization’s environment. Lastly, it should be said that the framework also
received some criticism from several authors. Some authors have for instance argued that the model
needs a 6th force called the ‘complementors’, in order to explain the reasoning behind strategic
alliances and joint ventures. This extended model is also known as the Value Net Model. However, even
though the criticism it got, Porter’s Five Forces is still one of the most used frameworks for strategy
development and is likely to remain that way in the near future.
