It is necessary to establish that information technology is understood as "the tools and methods used to collect, retain, handle or distribute information. The information technology is generally associated with computers and related technologies applied to
decision making (Bologna and Walsh, 1997: 1).
Information technology is changing the traditional way of doing
things, people working in government, private companies, that direct personal or professional working in any field use IT every day using internet cards credit, electronic payment of payroll, among other functions, that is why the role of IT in business processes such as manufacturing and sales have expanded greatly. The first generation of computers was designed to keep records and monitor the operational performance of the company, but the information was not timely because the analysis obtained on a given day actually described what had happened a week earlier. The current developments make it possible to capture and use information when it is generated, ie, have online processes. This has not only changed the way we do the work and the workplace but also has had a major impact on the way in which firms compete (Alter, 1999).Efficiently using information technology can gain a competitive advantage, but we need to find successful procedures for maintaining such advantages as a constant, and have alternative courses of action and resources to suit the needs of the moment, because the benefits do not always are permanent. The information system must be modified and updated regularly if you want to receive ongoing competitive advantages. The creative use of information technology managers can provide a new tool to differentiate human resources, products and / or services in respect of its competitors (Alter, 1999).This type of competitive pre-eminence can bring another group of strategies, such as a flexible and standards in time, capable of producing a wider variety of products at a lower price and in less time than the competition.The information technologies are a tool increasinglyimportant in business, however to implement a systeminformation from a company not guarantee that it gets results immediately or long term.
