What is a Defect?

A Defect, often referred to as a bug, is an error or flaw in a software application that causes it to produce incorrect or unexpected results. These anomalies can arise from various sources, such as coding mistakes, design errors, or issues with requirements. Defects can manifest in different ways, including crashes, incorrect calculations, unexpected behavior, or security vulnerabilities, and they can significantly impact the functionality and user experience of the software.

Identifying and addressing defects is a critical aspect of the software development process. Through rigorous testing and quality assurance practices, teams aim to detect and fix defects early to ensure that the final product meets the desired standards of quality and performance. Effective defect management involves not only correcting the issues but also understanding their root causes to prevent similar problems in the future. By maintaining a high level of software quality, organizations can enhance user satisfaction and reduce the risk of failures in production environments.
