The Challenge aims to unleash the creativity of tertiary students by sharing their ideas with innovation and make a positive impact on the environment. We believed the most powerful and engaging marketing is from their peers’ point of view. That’s why we applied design thinking by inviting users, our interns, to co-create the program and promotions with us. With our facilitations, they came up with the program name and gave concrete feedback on the theme design style, highlight information and visual languages that means to their peers.
