What is the benefit of independent testing?

Independent testing provides significant advantages, particularly in the aspect of objectivity. Independent testers are more likely to approach a product without preconceived notions or familiarity that developers may possess due to their extensive involvement in the development process. This fresh perspective enables independent testers to identify issues that the developers might overlook, as they may become too close to the code or functionality they created. Consequently, this can lead to the discovery of different defects and enhance the overall quality of the software.

Additionally, the unbiased nature of independent testers allows for a more thorough evaluation of the software from an end-user's viewpoint. They can critique user interface aspects and functionality with a critical eye that helps ensure the software meets diverse user needs and expectations. This independent perspective is essential for comprehensive risk identification and improving product quality.
