A fictional information system is accompanied by a dedicated support system, and there are two people responding to users’ requests. Unfortunately, the requests start piling up, and this is a problem for users as well as to the systems manager. Given that the support budget is limited, what would
Following on the previous question, how much of a system development project’s entire budget might go to system maintenance, and how can this figure be lowered?Data from previous questionCorrective maintenance accounts for about 75 percent of a system’s maintenance costs. Why is this
Corrective maintenance accounts for about 75 percent of a system’s maintenance costs. Why is this unfortunate?
