1. The model described by Michael Porter is the five forces of competitive advantage is a simple framework for the evaluation of the competitive strength and status of an organization. The cost should not be the only-one criterion to influence strategy. There are other forces also. The five models are classified into horizontal and vertical. There are three horizontal forces possible threats of new competitors, threats of existing rivals, and two vertical forces i.e., bargaining power of suppliers and customers. Horizontal threats are related to external sources and vertical threats are combined with vertical. The questions to be raised for any organization while making strategies can be derived from these five forces. At how ease another competitor can enter the same industry, whether there are other rivals giving the same offer to the customers, buyers, and suppliers’ power of bargaining easy or not? and the probability of the customer switching to a similar product. These questions should be answered which will reflect the strength of a company’s existing scenarios and its future scenario. 2. The main evidence he provides is an example from the aviation industry. There are threats of new entrants in the industry. In the aviation industry, large amount of resources especially financial are needed, the time to launch is large, and the requirement of a solid customer base. However, this threat is low. Similarly, the bargaining power of buyers is medium. There are various airlines to choose from, now tickets can be bought from apps, online websites, and agents. Different facilities are there for the passengers in the airline ranging from economy to business class. In the bargaining power of suppliers, is low. To manufacture an airplane, it cost more than $100 million with experienced and dedicated skilled manpower. Now, there are only two major companies ruling the market, Airbus and Boeing for large planes. In terms of the threat of substitute products, level of threat is low. Passengers won’t shift to cars and buses to travel for long durations. Only train can be a risk but it’s low. While , the level of threat is high for the rivalries between competitors in the same aviation industry. Now, in Canada, flair airlines are offering low fares in comparison to others. The giant airlines’ companies have more leverage and manipulate the consumers. Small companies are either merged or pushed out. 3. Yes, I agree that the five forces models in strategic planning are huge and can be applied to every business environment. These models will assist in visualizing new strategies and understanding the level of profitability and fierce competition among the companies. I also believe that these models can also be integrated with SWOT analysis and PESTLE. These 3 models will give a clearer picture while making strategies and implementing and knowing the strengths and weaknesses. The five forces are more useful when there are subject experts from all the sectors of the company such as sales, marketing, customer care, product managers etc. These can be utilized whenever there is or will be fierce and cutting-edge competition among competitors. To have sustainable profits for any company or organization, the five forces model should be applied. The identification of best practices and knowing the shortcomings and limitations can be crucial for the future too.
