In the market led economy, the commercial corporations have to justify any major investment decision with the economic value that investment may add within predicted period of time. For government and non-government organization, such decision depends on the improvement of the service rendered to the citizens and society. Simply, any major investment decision should be in line with business objective of any company. IT investment decision is not an exception. The difficulty of justifying an IT investment involves justifying the true value of technology within a fixed period of time. The traditional return on investment model will not work because of complicacy in measuring benefits from changing, reengineering or improving business processes and also rapid emergence and obsolescence of technology. The ROI calculation should quantify financially all tangible and intangible benefits technology can provide though quantifying intangible benefits is more challenging but very important in justifying an investment. The CIOs should involve business, finance and IT managers to decide whether an investment is worth. In the calculation of net present value, the finance manager should recommend the discounting factor considering the risk and benefit of a new project. A new IT project may be a transaction system, adaptive system or linking system where the linking system involves the highest and a transaction system involves the lowest risks and benefits.
