Definition - What does Defect Analysis mean?
Defect analysis is part of the continuous quality improvement planing in which defects are classified into different categories and are also used to identify the possible causes in order to prevent the problems from occurring. It helps projects to identify how issues can be prevented and in reducing or eliminating significant numbers of defects from being injected into the system.
Techopedia explains Defect Analysis
Defect analysis is a cooperative effort between the different consultants involved in a project. Their knowledge about the processes is put to use to help in defect analysis, and can be considered as part of the model for experience-driven incremental software process improvement. Defect analysis focuses on developing solutions to attack root causes of different commonly occurring defects. For this reason, past projects can also be analyzed to get the defect data. Thus, it aims at higher productivity and quality in future iterations by making use of the experience in its current iteration. The steps involved during defect analysis are collating defect data at the end of each iteration, identification of common defects with the help of different analysis techniques, performing causal analysis and prioritizing root causes, identification and development of solutions for root causes, implementation of solutions and review of the status of defect analysis at the end of the next iteration.
Defect analysis can be used for measurement of change before and after the introduction of the improvements. Defect analysis helps in improving both productivity and quality. It also helps in reducing the effort needed for defect removal on a long-term basis.
