What is the difference between system testing and acceptance testing in RSI Phase 5?

The correct choice highlights a critical distinction between system testing and acceptance testing. System testing is conducted to verify that the system meets specified requirements and adheres to various standards, ensuring compliance with technical specifications and design. It is primarily concerned with the behavior and functionality of the system as a whole, testing all integrated components for proper interaction.

On the other hand, acceptance testing focuses on validating whether the system meets the user's needs and expectations. This phase is often performed by end users or stakeholders who assess the system in real-world scenarios to determine if it is ready for deployment. Acceptance testing ensures that the system aligns with the business requirements and provides the value intended for the users.

Understanding this difference is crucial because it emphasizes the two distinct perspectives: technical adequacy in system testing versus functional adequacy and usability in acceptance testing. Recognizing these roles helps ensure that both approaches are executed thoroughly during the development lifecycle, ultimately leading to a more reliable and user-friendly final product.
