How do validation and verification differ in the context of ASAP?

In the context of ASAP, verification and validation serve distinct yet complementary roles in ensuring the quality and functionality of a product.

Verification is the process that ensures the product is built correctly, focusing on whether the development process and its deliverables meet the specified design specifications and requirements. This involves checking if the software aligns with the technical standards and design documents, often through activities like code reviews, unit testing, and system testing. Essentially, verification answers the question, "Did we build the product right?"

On the other hand, validation checks if the product meets the user's needs and requirements in real-world scenarios. This process is concerned with evaluating the final product to ensure it fulfills its intended purpose and provides value to the user. Methods typically used in validation include user acceptance testing and field trials. Validation answers the question, "Did we build the right product?"

This distinction highlights why the correct choice emphasizes verification in ensuring the product is built correctly and validation in ensuring it meets user requirements, outlining the critical roles each process plays in the development lifecycle.
