What is the primary objective of RSI Phase 5 in the software development lifecycle?

The primary objective of RSI Phase 5 in the software development lifecycle is to verify and validate the system before deployment. This phase is crucial as it focuses on ensuring that the software meets the specified requirements and functions correctly in its intended environment.

Validation involves checking that the software meets the needs of stakeholders and fulfills its intended purpose, while verification ensures that the codebase adheres to the defined requirements, standards, and specifications. This phase typically includes rigorous testing methods, such as system testing and acceptance testing, to identify and rectify any issues prior to the final deployment.

This focus on thorough testing contributes significantly to the reliability and quality of the software being delivered and helps mitigate risks associated with potential failures after release. It culminates in a higher level of confidence that the product will perform as expected when it is finally launched for end-users.
