Total Cost of Ownership
In addition to direct costs, systems developers must identify and document indirect
expenses that contribute to the total cost of ownership (TCO). TCO is especially important if the development team is assessing several alternatives. After considering the indirect costs, which are not always apparent, a system that seems inexpensive initially
might actually turn out to be the most costly choice. One problem is that cost estimates
tend to understate indirect costs such as user support and downtime productivity losses.
Even if accurate figures are unavailable, systems analysts should try to identify indirect
costs and include them in TCO estimates

Microsoft has developed a method for measuring total costs and benefits, called
Rapid Economic Justification (REJ), which is described in Figure 4-15. According to
Microsoft, REJ is a framework to help IT professionals analyze and optimize IT investments. Notice that the primary emphasis is on business improvement, rather than operational efficiency. As the Web site points out, the strategic role of IT investments should
be included, even when the specific benefits are difficult to quantify.
