👉 Closing engineering is the final phase of software development where the focus shifts from building and testing to refining, optimizing, and finalizing the software product. It involves reviewing all aspects of the system to ensure that it meets the initial requirements and user expectations, addressing any remaining bugs or issues, and fine-tuning performance, scalability, and security. This phase also includes documenting the final version of the software, preparing release materials, and coordinating with stakeholders for a smooth deployment. The goal is to deliver a polished, reliable, and user-friendly product that aligns with the project's objectives and is ready for production or release.
