Defect Management Systems and Their Benefit to Your Production Cycle
Errors happen. Manufacturing defects event. Tracking them and remedying them is part and parcel of being in business. In software development, as in any other field, there are going to be glitches, problems to be solved and so on. You hire your programmers not just for their skill with the programming languages you use, but also for their problem solving skills. Using them effectively means that you need to be able to zero in on problems and defects, and the discipline of doing this is called defect management.
Defect tracking tools are basically another name for bug tracking tools. They're central repository databases where testers can report the conditions that were under when performing a test of a given system, and where the error occurred. Good defect tracking tools Let the people working on quality assurance rate the frequency, severity and importance of defects reported by testing.
The other side of good defect management software is that it lets developers assign tasks to specific people, and the people who report defects can sign up for automatic notifications on the status of problems that they've submitted. This keeps your developers free because the hassle of communicating problem status reports has been automated.
Defect tracking tools also lets you sort defects and reported problems by common criteria, such as severity, frequency of appearance, difficulty in replication, and code base sources. This is useful when checking for regression issues, where fixing one bug may introduce a worse bug into a complex and interlinked coding project. (This is the reason why every piece of software that ever shipped has unresolved bugs in it. The reasons are not because the programmers are lazy, or ran out of time, but because the bugs that are left are deemed to be too illegally to fix .)
By keeping your defect management process working means having well educated testers and customers. In general, a problem report from an actual customer in an actual user environment is worth three or four reports from a testing and development lab, because if a user can find it, it's probably something that can be replicated.
Building your development process around defect management practices is just part of sound business making decisions. You need to make sure that your program goes out with the few possible defects, and that those defects are solved as efficiently as possible, and defect tracking software is the key to that.
