Firms with a competitive advantage over others typically have access to special resources that others do not or are able to use resources more efficiently, resulting in higher revenue growth, profitability, or productivity growth (efficiency), all of which ultimately in the long run translate into higher stock market valuations than their competitors.

Michael Porter's competitive forces model describes five competitive forces that shape the fate of the firm.
Figure 3-10
There are four generic strategies used to manage competitive forces, each of which often is enabled by using information technology and systems:
You can use the business value chain model to identify areas where information systems will improve business processes. You can also benchmark your business processes against your competitors or others in related industries, and identify and implement industry best practices.
A firm's value chain is linked to the value chains of its suppliers, distributors, and customers. Information systems can be used to achieve strategic advantage at the industry level by working with other firms to develop industry-wide standards for exchanging information or business transactions electronically, which force all market participants to subscribe to similar standards. Such efforts increase efficiency, making product substitution less likely and perhaps raising entry costs., Internet technology has made it possible to create highly synchronized industry value chains called value webs. A value web is a collection of independent firms that use information technology to coordinate their value chains to produce a product or service for a market collectively. It is more customer-driven and operates in a less linear fashion than the traditional value chain. Figure 3-12
A large corporation is typically a collection of businesses. Information systems can improve the overall performance of these business units by promoting synergies and core competencies.
Business models based on a network may help firms strategically by taking advantage of network economics. In network economics, the marginal costs of adding another participant or creating another product are negligible, whereas the marginal gain is much larger. For example, the more people offering products on eBay, the more valuable the eBay site is to everyone because more products are listed, and more competition among suppliers lowers prices. Another network-based strategy is the virtual company, or virtual organization, which uses networks to link people, assets, and ideas, enabling it to ally with other companies to create and distribute products and services without being limited by traditional organizational boundaries or physical locations. One company can use the capabilities of another company without being physically tied to that company. The traditional Porter model of competitive forces assumes a relatively static industry environment; relatively clear-cut industry boundaries; and a relatively stable set of suppliers, substitutes, and customers. With the emergence of the digital firm and the Internet, some modifications to the original competitive forces model are needed. Some of today's firms are much more aware that they participate in business ecosystems, loosely coupled but interdependent networks of suppliers, distributors, outsourcing firms, transportation service firms, and technology manufacturers. In a business ecosystem, cooperation takes place across many industries rather than many firms. Figure 3-13
Business ecosystems can be characterized as having one or a few keystone firms that dominate the ecosystem and create the platforms used by other niche firms. Keystone firms in the Microsoft ecosystem include Microsoft and technology producers such as Intel and IBM. Niche firms include thousands of software application firms, software developers, service firms, networking firms, and consulting firms that both support and rely on the Microsoft products. Which of the following organizations research the new Internet technology to improve its capabilities?Internet Engineering Task Force. What is responsible for the Internet domain name system and the allocation of IP addresses?ICANN is a public-private partnership that is responsible for the following functions related to internet names and numbers: Allocation of IP address space. ICANN manages the distribution and allocation of IP version 4 and IP version 6 network addresses through five regional internet registries.
Which of the following is an example of instant messaging service?Some examples of widely used IM services are Google Talk (commonly called Google Chat), Slack, Jabber, Spark, and many more. The advantages of IM are that messages are sent and received instantly in real time and responses are organized in a “conversation” format that supports two-way communication.
Which of the following was created for the transfer of hypertext documents across the Internet?Hypertext Transfer Protocol (HTTP) is a method for encoding and transporting information between a client (such as a web browser) and a web server. HTTP is the primary protocol for transmission of information across the Internet.
