Why cost of fixing a defect increases depending on how late it is found in the SDLC?
For bug fixes, earlier is better (and cheaper) The cost of fixing an issue increases exponentially as the software moves forward in the SDLC. The earlier bugs are introduced (e.g., during the design phase), the higher their potential impact, and the more complex they can be to resolve.
What if you find bug in production?
When a defect is found in production, you wish to fix it ASAP but this isn’t always correct. It frequently happens that fixing one bug leads to the appearance of the new ones.

What is bug fix rate?
1) Fixing rate on the whole: after counting all fixed bugs and all closed bugs of the whole project, the community’s bug fixing rate is defined as the ratio of the fixed bugs to the closed bugs. 2) Fixing rate by year: first count fixed bugs and closed bugs of the whole project by year.
What is bug cycle in testing?
Bug life cycle also known as defect life cycle is a process in which defect goes through different stages in its entire life. This lifecycle starts as soon as a bug is reported by the tester and ends when a tester ensures that the issue is fixed and won’t occur again.
What are product bugs?
What Are Product Bugs? Wikipedia defines software bugs as “an error, flaw or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.”
What do we do when there is a known bug at the time of software release?
