During November 2024, Mamapapason developed a comprehensive workflow diagram for a To-Do List Management Program in the eunbi-kim/24_2_W_SeProj repository. Using Draw.io and XML, they mapped out user interactions and system processes, including login, subject or course registration, and full to-do item management such as adding, deleting, modifying, and sorting tasks. The diagram also detailed display options for completed and important items, providing a clear visual reference for the team. By focusing on diagramming and system design, Mamapapason improved project clarity and established a solid foundation for future implementation, though no bugs were addressed during this period.
