During March 2025, Shi Sherng focused on enhancing the cost-effectiveness modeling diagram within the Yihe-Harry/DSA3101-Group-Project repository. He addressed a data presentation issue by renaming a retraining cycle file and refining both metadata and diagram content, ensuring improved traceability and alignment with the final model lifecycle. Working primarily with XML and leveraging skills in diagramming and refactoring, he maintained rigorous change-tracking through Git version control. Although the updates did not introduce new features or alter functionality, they improved data accuracy and maintainability, supporting clearer stakeholder reviews and future development. The work demonstrated careful attention to documentation and process integrity.
