Worked on the eunbi-kim/24_2_W_SeProj repository to design and refine diagrams supporting a To-Do List management system. Focused on creating a new Untitled Diagram.drawio and enhancing its layout to clearly represent user interactions and system flows. Emphasized documentation quality and design traceability, ensuring that the diagrams serve as effective onboarding and reference materials for both developers and stakeholders. Utilized Draw.io for diagramming and XML for asset management, applying best practices in documentation and version control. No bugs were addressed during this period, with efforts concentrated on improving cross-team collaboration through well-structured visual documentation and clear system modeling.
