IT can have a significant impact on organizational performance, but it can also be a major inhibitor of change and can be a resource-hungry investment that often disappoints. Organizations can best influence the success of IT projects at the decision stage by rejecting poor ones and accepting beneficial ones. However, little is known about IT decision processes. Research demonstrates the importance of managing strategic IT investment decisions (SITIDs) effectively. SITIDs form part of the wider range of corporate strategic investment decisions (SIDs) that cover all aspects that the organization might wish to invest in. SIDs will then have different degrees of IT intensity that may impact on outcome. IT investment intensity is the degree to which IT is present in an investment decision. Here, IT investment intensity is defined as the ratio of IT spending to total investment. The higher IT investment intensity, the more important IT is to the whole investment. For example, Chou et al. (1997) find IT investment intensity to be negatively associated with SID effectiveness. The concept of IT intensity is similar to, but also somewhat different from, the concept of information intensity. Information intensity may be defined as the degree to which information is present in the product or service of a business (Porter & Millar, 1985).
