Ideally, the software would be developed and passed through comprehensive verification on real devices quickly, efficiently, and without flaws. The development team is satisfied, as are the testers and, most importantly, the end-users.
But since we don’t live in a perfect world, testers must deal with numerous bugs, defects, and flaws before a website or app is ready for public usage. Solid quality assurance process metrics must be in place, since users expect nothing short of excellent.
Following, we will learn about the defect management process, the Need for a Defect management process, and much more…
The Need for a Defect Management Process
The importance of defect management is a key component of software testing strategies. If defects are not properly tracked and managed, they will inevitably escape into production. This will negatively affect the user experience, damage credibility, and possibly lead to negative reviews that discourage further usage.
In this tutorial, we explain the basics of defect management and how it helps create a better product. To begin with, understand what a defect is.
What is a Defect?
A defect is an error or a bug in the application that was created. For example, there may be a broken link or an error in the function. A developer or programmer can make mistakes or errors while making an application. If there are mistakes in the application, it means there are flaws in the application. These flaws are referred to as defects.
Different organizations use different names to describe this variation, such as bug, problem, incident, or issue.
During the testing process, if the expected result and the actual result deviate from the actual result, then the result will be a defect. These defects occur because of mistakes in logic or coding, which result in failure.
Note: When a tester discovers a bug or defect, it is required to convey the same to the developers. Thus, they report bugs with the detailed steps and are called Bug Reports, Issue Reports, Problem Reports, etc.

The Defect Management Process
There is a systematic approach to identifying, tracking, and resolving defects in software development called the Defect Management Process. Typically, it involves the following steps:
- Defect identification – Defects are identified through a variety of testing activities, such as unit testing, integration testing, and user acceptance testing.
- Defect logging – Defects are logged in a defect tracking system, and include details such as description, severity, and priority.
- Defect triage – The triage process involves deciding which defects are the most important and how much work is needed to fix them.
- Defect assignment – Depending on their expertise and availability, defects are assigned to developers or testers.
- Defect resolution – The assigned personnel fix the code, update the documentation, or do other things needed to fix the defects.
- Defect verification – Once the defect is fixed, the tester checks to make sure that it has been fixed correctly and doesn’t introduce any new defects.
- Defect closure – Once the defect has been verified, it is closed and the status in the defect tracking system is updated.
- Defect reporting – To provide visibility into the defect management process, regular reports on the status of defects, including the number of open defects, the number of defects resolved, and the average time to resolve defects, are generated.
Throughout the software development life cycle, the Defect Management Process helps to ensure that defects are identified, tracked, and resolved in a timely and efficient manner, leading to higher software quality and reliability.
Goals of Defect Management Process (DMP) :
- Prevent the defect
- Detection at an early stage
- Reduce the number of defects in the software
- Resolving or fixing defects
- Improving the process and performance of the software.
