Mismanagement: A fourth explanation is that the new system has not been implemented and
managed well. Some believe that people often simply build bad systems, implement them poorly,
and rely on technology fixes when the organization has problems that require a joint
technology/process solution. Rather than increasing outputs or profits, IS investments might
merely be a temporary bandage and may serve to mask or even increase organizational slack and
inefficiency.

investments.

32) Explain the three types of arguments commonly made in the business case for an information
system. Give an example for each.
page-pf2
Business case arguments based on fact: Many people, including most chief financial officers,
want to see the business case for an information system based on some convincing, quantitative
analysis that proves beyond the shadow of a doubt that the benefits of the system will outweigh
the costs. The most common way to prove this is to provide a detailed cost-benefit analysis of the
information system. Arguments are based on data, quantitative analysis, and/or indisputable
factors. An example of a business case based on facts is, "This analysis shows that implementing
the inventory control system will help us reduce errors by 50 percent, reduce operating costs by
15 percent a year, increase production by 5 percent a year, and will pay for itself within eighteen
months."
