Faults found by users are primarily due to which factor?

The most accurate reason for faults found by users is tied to the combination of poor software quality and inadequate testing. When software is developed without adhering to quality standards, or when testing processes are ineffective, it is more likely that defects will remain undetected until users interact with the software. Poor software may have intrinsic flaws, such as incorrect algorithms or design issues, while poor testing might involve insufficient test coverage or ineffective testing strategies that fail to identify these defects before the software is released.

In this context, users encountering faults suggests that both the quality of the software itself and the thoroughness of the testing process are critical factors contributing to the experience of finding faults. An understanding of both dimensions helps emphasize the importance of rigorous testing practices and effective software design to deliver a product that meets user expectations and minimizes defects.
