In modern web service development, which involves professionals with diverse expertise, the process continues to accelerate and grow in complexity. Ensuring smooth information sharing within the team is crucial for success, as misunderstandings easily arise from differences in background knowledge and contextual interpretation. Consequently, understanding the context in which information is exchanged is vital to preventing these communication discrepancies. This study builds on prior research to propose a method for mitigating project risks by visualizing information transmission during the requirements definition and design phases using a Concept Map Recomposition Method. In this approach, the sender first expresses the intended content as a concept map—referred to here as a shared understanding map—and breaks it down into nodes and links. The receiver then recomposes these elements and overlays them on the original map, enabling the detection of differences at the propositional level. Previous evaluations in educational settings have confirmed the effectiveness and practicality. In this study, the method was implemented in a BizDevOps team working on an actual web service project to detect communication discrepancies in information sharing and reduce project risks. Findings showed that the method successfully detected the discrepancies, was considered cost-effective and useful by participants, and promoted a deeper shared understanding among team members. Specifically, the results indicated that: (1) the method effectively detected communication discrepancies, (2) participants deemed it both cost-effective and practical, (3) transmitters could represent their intended meaning using the concept map, and (4) the recomposition process itself helped receivers deepen their understanding.
