The case study on Software Development, Inc. (SDI) reviews the introduction of thirty-eight new or revised software packages for the costs of defects. Do an analysis of Table 23.2. If you look at the software introductions with more than fifty defects and those with fewer than twenty-five defects, what general conclusions can you come to concerning the product costs, training costs, prevention costs, and maintenance/service costs of SDI?
What will be an ideal response?
Maintenance/service costs are substantially lower for the software introductions with fewer than 25 defects. There is no discernable difference, however, for the product costs or training costs.
