What is the purpose of system testing in systems analysis?

The purpose of system testing in systems analysis is to ensure that the system meets the specified requirements and is free of defects. This phase is crucial because it verifies that the system functions as intended in the real-world environment. System testing involves checking whether every part of the application works correctly and if the system as a whole meets the initial specifications set during the requirements gathering phase. It includes functional testing, performance testing, and security testing, among other techniques.

This testing phase is essential not only for finding and fixing defects prior to deployment but also for validating that the system fulfills the needs of its users and stakeholders. By confirming that the system behaves as expected, system testing contributes to the overall quality assurance process, ensuring reliability and user satisfaction when the system goes live.
