Information Technology in Business

...Riordan Manufacturing business chose to outsource their information technology (IT) systems and services for a variety of reasons.

It Doesn’t Matter by Nicholas G. Carr

...executives are wrong who believe that information technology is a strategic value that provides a competitive advantage. He says: ‘As information technology’s power and ubiquity have grown, its strategic importance has diminished. The way you approach information technology investment and management will need to change dramatically.’ Scarcity gives the capacity to be the basis for a sustained competitive advantage. Because information technology is easily accessible now, the strategic importance of information technology has been reduced. The main focus of this article is that organizations should handle information technology as a product in which it should reduce vulnerabilities, pursue to keep costs low, and avoid taking risks. Information technology’s power and ubiquity has begun to change this technology from strategic resources into factors of production. The three basic functions of information technology are storage, processing, and transport of data which has become one of the most important key to do business. Carr also argues that managers must focus on managing their time and also spend a good time understanding the importance of technology and how it impacts the firm level.

Information Ethics and Security

...Introduction Information is a valuable corporate asset and important to our business. With regard to the situation that Brawner offers me a large sum of money for the email addresses and phone numbers of all my customers, what should I do? This essay aims to provide my response and dig out the root reasons of my business decision-making from two aspects of information ethics and information security. Information Ethics With the rapid development of information technology nowadays, people pay more attention to ethics and security. In recent years, many increasingly frequent corporate scandals have shed new light on the meaning of ethics and security. When the behavior of a few individuals can destroy billion-dollar organizations, the value of ethics and security should be evident. As mentioned in the case, Brawner would offer me a large amount of money in order to purchase my customer lists, which include the customers’ email addresses and phone numbers. Undoubtedly, it is neither ethical nor legal for me to accept Brawner’s money and give him the customers’ information.

Instead, it is the appropriate management of technology that creates a competitive advantage. Why IT does not matter The whole world of e-commerce and using IT within businesses started by inventing the personal computer and connecting the world and business with theirs customers via internet. The spending of the resources on IT by businesses was increasing more and more towards the end of the century. In the last decade it was nearly 50% of the capital expenditures. Carr (2003) says that any business has equal access to the computer technology because it is affordable and as the technology evolves and innovates, the price goes down more rapidly. That means the IT does not gives the advantage to the organization, but it’s the way organization manages the IT, how it aligns the IT with the organizations business goals that gives it the competitive edge against the competition. IT becomes just a commodity and cost of doing business. What makes it truly strategic is tis scarcity.
