How does OAN ensure application functionality following its creation?

The correct answer highlights the importance of Quality Assurance (QA) in maintaining the functionality of applications after they are created. In a development environment, once an application is built, it is crucial to ensure that it operates as intended and meets the required standards. Incorporating the application into a QA process allows for thorough testing, which helps identify bugs, usability issues, and ensures compatibility with existing systems.

Quality Assurance involves systematic testing and validation against specifications, enabling teams to catch any potential issues before the application is released or updated. This ensures that the application functions correctly and reliably in various scenarios. Regular updates to an application's functionality need to be evaluated through QA, as changes can introduce new risks or degrade the user experience. Thus, including applications in a Quality Assurance process is vital to ensure continued functionality and performance standards post-creation.
