The research objective of this paper is to develop a storytelling-based knowledge sharing application that enables users to co-create their own stories for both individuals and groups. To address this, a design science research methodology was applied for elucidating users' requirements. As empirical evidence, a case study was con- ducted on the children's book industry to synthesize a knowledge-sharing design application named “StoryWeb”. Usability tests were conducted to reconfigure users' feedback and suggestions after two StoryWeb prototypes were developed. This study makes three main contributions. First, it empirically tests individual's or group's creativity and co-creation by a view of knowledge sharing. Second, it methodologically applies a design thinking approach into a knowledge-sharing study. Third, it also practically suggests feasible guidelines for the creativity and innovation research community on which features of storytelling-based applications can be configured.
