Why organization need I.T strategy?

Information Technology Strategy is basically assigning ownership of IT direction and software choices to a controlling body. The advantages of such a system is that you a a unified corporate look at what software/hardware the the businesses systemswill be ran upon and a body whose job it is to support those chosen systems. In the absence of such a body any software is allowed to be brought in and you wind up with the user community being responsible for their own application source and the need for each user to know how to share their information with the rest of the company. It may not be the cheapest route but it does help set standards which everyone in the company follows and trains and knows how to work with.
