Regardless of size and industry, every enterprise is dependent upon information technology, and must have a strategy for how to employ it, especially as the internet becomes more pervasive. Information technology strategy is an enabler of business strategy. Not only must an enterprise manage relationships with its constituencies, but it must be able to connect with them electronically through data arteries – information supply, value, and demand chains. The information supply and demand chains are external; the information value chains are internal.
An information technology strategy is a special case functional strategy because every function in the enterprise requires electronic information delivery capabilities, and many require electronic process control also. In very large enterprises, strategy may be formulated at both the enterprise and organizational unit levels.
As websites such as Facebook, LinkedIn, MySpace, Plaxo, and Twitter become more pervasive in business, linkages between application systems and databases and social networking websites will be more important to enable constituencies to communicate both collaboratively and cooperatively. Just as email has become a primary method of communication between enterprises and their constituencies, so will social networking sites especially for advertising and ecommerce.
Business intelligence information can be used to identify opportunities for competitive advantage. However, information technology itself can be an enabler of competitive advantage, especially when there are opportunities to digitize products or deliver information products electronically. In such cases, business strategy is inseparable from information technology strategy.
Information technology comprises the analytical and operational application systems, databases, and technical infrastructure (hardware and networks) of an enterprise. Not all computer technologies are information based. Computer technology is used for process control applications in special purpose equipment. However, connectivity is essential as applications become more integrated. As digital construction and manufacturing practices develop through such technologies as computer-aided design/computer-aided manufacturing (CAD/CAM), the processes, the control of processes, and the products and/or services delivered by processes all rely upon information technology for connectivity.
