Abstract—Defect remains in the whole life of software
because software is developed by humans and ‘to err is human’.
The main goal of well-organized software defect management
process is to produce quality software with the least number of
defects to reduce the impact of problems in the organization.
Defect management process includes three levels which are
defect detection, defect analysis and defect prevention to
eliminate and mitigate the potential defects. At first level test
the software work product until the entire defects are identified
and fixed. The second level is defect analysis in this level
previously identified defects are analyzed and time is spent to
look their root causes and why they were not detected earlier.
The ultimate goal of third level defect prevention is to prevent
the defects from recurring in the future. The research question
of this study is how to produce quality software with the least
number of defects? A well establish a defect management
process is one of the success factors of producing a software
system within the time and budget. In this paper author have
proposed a defect management process model and finds
observations by applying the proposed model in one of the case
organization. The major contribution of this study is to
establish a defect management process model in an organization
to reduce the number of defects and produce a quality software
product.
