As the third paper on design management in a series of three, design science research activity was carried out. Based on the problems identified within the first paper and the knowledge base established in the second paper, theoretical and practical design process and management models were developed. Within the language of two-step abductive reasoning, the theoretical model served as a solution concept for developing a practical solution. This research reports the first cycle of design science research. The result is the description of "to-be" to facilitate the change management within the case study organization.
