Which stage involves checking if the newly created system functions as expected?

The stage that involves checking if the newly created system functions as expected is the testing phase. This phase is critical in the development lifecycle as it ensures that the system performs its intended functions correctly and meets specified requirements. During testing, various methods such as unit testing, integration testing, and system testing are employed to identify any defects or issues. This process allows developers to address problems before the system is deployed.

The primary objective of the testing phase is to validate that the system behaves as expected under different conditions and that it can handle all edge cases. This ensures reliability and functionality, minimizing the chances of failure once the system is in use. The emphasis is on thorough examination and validation of the system’s features and performance characteristics.

Other stages such as evaluation primarily focus on assessing the overall effectiveness of the system after deployment, documentation entails creating manuals and user guides for future reference, and production refers to the actual rollout of the system for end users.
