Abstract
Mobile game development is growing in scale, and the number of developers working on one title is increasing. Since agile is used in large-scale projects in games, the ability to study specifications across multiple fields is becoming more important. Therefore, I held a workshop at Ideathon with the aim of experiencing cross-disciplinary specifications. The requirements for applying Mind Map to group work for this purpose, evaluation methods, and workshop design requirements such as student composition are not yet clear, so I will examine them in this paper.
