In the world of today, the process of information technology is a part of organizations due to the importance of information systems. These are the processes through which one derives solutions to the challenges faced in organizational and management problems. There is also a view among experts that the quantity of interaction between the IT department of the organization and other units are what determines the success of any organization. The entire process of IT can be used in a centralized or decentralized manner. The structure of IT in any organization should provide assistance in its strategy and must conduct the needed research for this purpose. (Centralized versus Decentralized Information Systems in Organizations).

             Analysis: .

             Today, several organizations in all sectors of industry, commerce and government are based on their information systems. In some industries like telecommunications, media, entertainment and financial services, the survival of the organization itself depends on how efficiently it applies to information technology -- IT. A new system called e-commerce has now burst into the arenas of international trade, and that makes IT as a method of conducting modern business. This is now changing the attitudes of the business leaders and IT is no longer only a method of performing existing business, but should also be used for development as that is expected to provide advantages in competition. Thus many organizations today want to develop a more strategic approach to their use of IT, but more have probably arrived at their present situation due to their adoption of short-term 'tactical' decisions with IT. (The Evolving Role of Information Systems and Technology in Organizations: A Strategic Perspective).

             At the same time, many organizations would wish that it were possible to rethink their investments, or begin with a clean sheet, but that is impossible as they have a 'legacy' system built up from their approach to IT in the past.
