The quality of a product will only be as good as the debugging capabilities that a developer has available. Developers must be able to analyze and track the exact root of a specific bug or understand what’s happening on every line of code. Without such capabilities, developers might apply workarounds most of the time, using best guesses instead of fixing the real issues.
Depending on the maturity of the development organization, it’s estimated that developers can spend up to 80% of their time in debugging. If they could isolate defects before they make it into a release build, they would have a lower defect injection rate. Therefore, the organization’s quality metrics could be reached much more quickly, reducing the development efforts overall.
