Also, an organization should determine how IT infrastructure is used; there are four views of firm wide IT infrastructure: none, utility, dependent, or enabling ( (Table 1). One of these four views is typically taken with individual firms. No particular view is best for all firms, but typically one view is more appropriate for a business according to their business and IT maxims. There are two different approaches in enterprise IT infrastructure planning: maxim route and deals making route. The maxim route assumes that both business and IT management look at the company as a whole. The deal making route focuses on a more immediate need of a business. In the deal-making route, typically there are only three views: none, utility, or dependent.
