Jinhwa Kim focused on foundational documentation and planning for a new To-Do List feature in the eunbi-kim/24_2_W_SeProj repository. Over the course of one month, Jinhwa created a detailed task management diagram using XML-based tools, capturing the intended architecture and user experience for the upcoming feature. This artifact served to align stakeholders and reduce implementation risks by clarifying requirements and workflows before development began. While no bugs were addressed during this period, Jinhwa’s work enhanced repository traceability and set the stage for efficient future development, demonstrating depth in documentation and technical planning within the context of software engineering projects.
