The difference between verification and validation in software quality assurance is as follows:

1. Verification ensures that the software is built correctly: This means that during the verification process, we check if the software is being developed in the right way. It involves reviewing design documents, specifications, code, plans and other documentation. The goal is to ensure that all requirements have been clearly specified and that each requirement is traceable to system requirements.

2. Validation ensures that the right software is built: This means that during the validation process, we check if the software meets the user's needs and requirements. It involves actual testing and takes place after verifications are completed. The goal is to ensure that all functions work as expected and errors are identified and corrected.

The statement "Verification is manual, while validation is automated" is not necessarily true. Both verification and validation can be manual or automated depending on the methods used.

The statement "Verification is done by developers, while validation is done by testers" is also not necessarily true. Both developers and testers can be involved in both verification and validation processes.

The statement "Verification focuses on functionality, while validation focuses on performance" is not entirely accurate. Verification focuses on whether the software is being built correctly according to the specified requirements, while validation focuses on whether the software meets the user's needs and requirements, which can include both functionality and performance.
