    All three businesses have a Competitive advantage. What does it mean when a company has a competitive advantage? What are the factors that play into it? According to Michael Porter in his book “Competitive Advantage: Creating and Sustaining Superior Performance,” a company is said to have a competitive advantage over its rivals when it can sustain profits that exceed the industry's average. Porter identified two basic types of competitive advantage:

    • Cost advantage: When the firm can deliver the same benefits as competitors but at a lower cost. McDonald's and Walmart both utilize economies of scale to maintain their cost advantage.
    • Differentiation advantage: When a firm can deliver benefits that exceed those of competing products. Apple’s innovative products that complement each other and share the same operating system offer a unique product that gives consumers a sense of exclusivity, and their trade-in programs build consumer loyalty.

    The question, then, is: How can information technology be a factor in achieving Competitive advantage? We will explore this question by using:

    • Two analysis tools from Porter’s book “Competitive advantage: Creating and Sustaining Superior Performance:
      • The value chain
      • The Five Forces model.
    • Porter’s analysis in his 2001 article “Strategy and the Internet.”

    The Value Chain

    In his book, Porter analyzes the basis of competitive advantage and describes how a company can achieve it using the value chain as a framework. A value chain is a step-by-step business model transforming a product or service from an idea (i.e., materials) to reality ( i.e., products or services). Value chains help increase a business’s efficiency so the business can deliver the most value(i.e., profit) for the least possible cost. Each step (or activity) in the value chain contributes to a product or service's overall value. While the value chain may not be a perfect model for every type of company, it does provide a way to analyze just how a company is producing value.

    The value chain is made up of two sets of activities: primary activities and support activities. We will briefly examine these activities and discuss how information technology can create value by contributing to cost advantage or differentiation advantage, or both.

    The primary activities are the functions that directly impact the creation of a product or service, its sales, and after-sales service. The goal of the primary activities is to add more value than they cost. The primary activities are:

    • Inbound logistics: Purchasing, Receiving, and storing raw materials. Information technology can make these processes more efficient, such as with supply-chain management systems, which allow the suppliers to manage their own inventory. Starbucks has company-appointed coffee buyers that select the finest quality coffee beans from producers in Latin America, Africa, and Asia.
    • Operations: Any part of a business involved in converting the raw materials into the final products or services is part of operations. From manufacturing to business process management (covered in chapter 8), information technology can provide more efficient processes and increase innovation through information flows.
    • Outbound logistics: These functions include order processing and warehousing required to get the product out to the customer. As with inbound logistics, IT can improve processes, such as allowing for real-time inventory checks. IT can also be a delivery mechanism itself.
    • Marketing/Sales: The functions that will entice buyers to purchase the products (advertising, salesforce) are part of sales and marketing. Information technology is used in almost all aspects of this activity. From online advertising to online surveys, IT can innovate product design and reach customers like never before. The company website can be a sales channel itself.
    • Service: The functions a business performs after the product has been purchased, such as installation, customer support, complaint resolution, and repair to maintain and enhance its value, are part of the service activity. Service can be enhanced via technology as well, including support services through websites and knowledge bases.

    The support activities are the functions in an organization that support and cut across all primary activities. The support activities are:

    • Firm infrastructure: Organizational functions such as finance, accounting, ERP Systems (covered in chapter 9), and quality control, all of which depend on information technology.
    • Technology development: Technological advances and innovations support the primary activities. These advances are then integrated across the company to add value in different departments. Information technology would fall specifically under this activity.
    • Procurement: Acquiring the raw materials used in the creation of products and services is called procurement. Business-to-business e-commerce can be used to improve the acquisition of materials.

    A value chain is a powerful tool in analyzing and breaking down a company into its relevant activities that result in higher prices and lower cost, by understanding how these activities are connected and the company’s strategic objectives, companies can identify their core competencies and insight into how information technology can be used to achieve a competitive advantage.

    Look at this example of the Starbucks value chain model analysis that includes a short video by Prableen Bajpai: Analyzing Starbucks Value Chain Model.

    Porter’s Five Forces

    Porter recognized that other factors could impact a company’s profit in addition to competition from their rivals. He developed the “five forces'' model as a framework for analyzing the competition in an industry and its strengths and weaknesses. The model consists of five elements, each of which plays a role in determining an industry's average profitability.

    In 2001, Porter wrote an article entitled ”Strategy and the Internet,” in which he takes this model and looks at how the Internet(and IT) impacts an industry's profitability. Although the model's details differ from one industry to another, its general structure of the five forces is universal. Let’s have a look at how the internet plays a role in Porter’s five forces model:

    • Threat of New Entrants: The easier it is to enter an industry, the tougher it will be to profit in that industry. The Internet has an overall effect of making it easier to enter industries. Traditional barriers such as the need for a physical store and sales force to sell goods and services are drastically reduced. Dot-coms multiplied for that very reason: All a competitor has to do is set up a website. The geographical reach of the internet enables distant competitors to compete more directly with a local firm. For example, a manufacturer in Northern California may now have to compete against a manufacturer in the Southern United States, where wages are lower.
    • Threat of Substitute Products: How easily can a product or service be replaced with something else? The more types of products or services there can meet a particular need, and the less profitability will be in an industry. For example, the advent of the mobile phone has replaced the need for pagers. The Internet has made people more aware of substitute products, driving down industry profits in those industries being substituted. Any industry in which digitized information can replace material goods such as books, music, software is at particular risk ( Think, for example, Amazon’s Kindle and Spotify).
    • Bargaining Power of Suppliers: Companies can more easily find alternative suppliers and compare prices more easily. When a sole supplier exists, then the company is at the mercy of the supplier. For example, if only one company makes the controller chip for a car engine, that company can control the price, at least to some extent. The Internet has given companies access to more suppliers, driving down prices. On the other hand, suppliers now also have the ability to sell directly to customers. As companies use IT to integrate their supply chain, participating suppliers will prosper by locking customers and increasing switching costs.
    • Bargaining Power of Customers: A company that is the sole provider of a unique product has the ability to control pricing. But the Internet has given customers access to information about products and more options (small and big business) to choose from.
    • Threat of Substitute Products: The more competitors in an industry, the bigger a factor price becomes. The visibility of internet applications on the Web makes proprietary systems more difficult to keep secret. It is straightforward to copy technology, so innovations will not last that long. For example, Sony Reader was released in 2006, followed by Amazon Kindle in 2007, and just two years later, Barnes and Noble Nook, which was the best-selling unit in the US before iPad (with built-in reading app iBooks) hit the market in 2010. (Wikipedia: E-Reader, 2020)

    According to this model, the company's average profitability depends on the five forces' collective strength. If the five forces are intense, for example, in the airline industry, almost no company makes a huge profit. If the forces are mild, for example, the soft drink industry, there is room for higher profits. The Internet provides better opportunities for companies to establish strategic advantage by boosting efficiency in various ways, as we will see in the next section. However, the internet also tends to dampen suppliers' bargaining power and increase the threat of substitute products by making it easier for buyers and sellers to do business. Thus, the Internet (and, by extension, information technology in general) has the overall impact of increasing competition and lowering profitability. This is the great paradox of the internet.

    While the Internet has certainly produced many big winners, the overall winners have been the consumers, who have been given an ever-increasing market of products and services and lower prices.
