What is the primary purpose of systems testing in the SDLC?

The primary purpose of systems testing in the Software Development Life Cycle (SDLC) is to ensure that the system meets specified requirements and functions correctly. This phase involves evaluating the complete integrated system to verify that it fulfills the intended objectives outlined during the requirement analysis phase.

During systems testing, various testing methods are employed, such as functional testing, performance testing, and security testing, to thoroughly assess the software. This comprehensive evaluation aims to identify any discrepancies between the expected outcomes and the actual performance of the system, allowing developers to fix issues before the system goes live.

By confirming that the software adheres to the established requirements and performs as intended, systems testing helps to minimize defects, enhance the quality of the software, and increase user satisfaction once the system is deployed. This focus on validation and verification is crucial for delivering a reliable and effective software product.
