| 20080201611 | Defect Resolution Methodology Target Assessment Process - Embodiments of the invention are generally related to computer systems, and more specifically to the analysis of defects in computer software products. Defects uncovered during software testing may be stored in a data structure as data defects, code defects, or environment defects, along with further data describing a particular nature of the defects. The defects may be analyzed to determine a particular problem area causing the defects. If a particular class of defects is determined to be the dominant class of defects encountered during testing, an analysis path of that class of defects may be followed to determine a cause for the defects in the respective class. Therefore, corrective measures tailored to resolving the defects associated with the determined cause may be taken. | 08-21-2008 |
