Also, an organization should determine how IT infrastructure is used; there are four views of firmwide IT infrastructure: none, utility, dependent, or enabling (Weill, 1993) (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.
