Detailed explanation-4: -Software bugs occur as a result of undefined or continuously changing requirement, as well as software complexity, programming errors, deadlines, poor communication, reporting errors, and deviations. The lack of software glitches eliminates the need for testing.

Detailed explanation-5: -When requirements are implemented in the wrong way, and resulting a deviation in customer specifications which leads to a defect. A bug is an error in the software that causes malfunction. A flaw in the product that reduces its usability of the product.
