This interdisciplinary project combines the two disciplines of IB Design Technology and Business Management. Teachers spent several weeks of cross-disciplinary teaching based on the core concepts at the intersection between the subjects. During the process, students of business subject were responsible for brand background research and data analysis, while students of design subject created prototypes of new products based on the results of discussions with business students. Students shared the product development process in the form of a briefing at the press conference and demonstrated the product prototype after several weeks.
