as illnesses in medical science. Defects, as defined by software developers, are variances from a desired attribute. These attributes include complete and correct requirements and specifications as drawn from the desires of potential customers. Thus, defects cause software to fail to meet requirements and make customers unhappy. And when a defect gets through during the development process, the earlier it is diagnosed,

the easier and cheaper is the rectification of the defect. The end result in prevention or early detection is a product with zero or minimal defects. How serious are defects in software development? In the United States, up to 60 percent of software developers are involved in fixing errors, Computer Finance Magazine reported in 1998. This fact alone, without consideration of providing the quality needed to please customers, shows the value of preventing software defects. Advantage of Early Defect Detection Data to support the need for early fixes of software defects is supplied by several reports. The National Institute of Standard Technology (NIST) published a study in 2002 noting that the cost of fixing one bug found in the production stage of software is 15 hours compared to five hours of effort if the same bug were found in the coding stage. The Systems Sciences Institute at IBM has reported that the cost to fix an error found after product release was four to five times as much as one uncovered during design, and up to 100 times more than one identified in

In general, there are two categories of cost associated with errors – cost of identification and cost of correction. This paper addresses an important element of the second category – the behavior of the cost of error correction as a project progresses. It is based on a study that used three approaches to determine the relative costs: the bottom-up cost method, the total cost breakdown method, and the top-down hypothetical project method. The approaches and results described in this paper presume development of a hardware/software system having project characteristics similar to those used in the developmen
