A major advantage of the DTMethod is its clear structure, which is in accordance with the latest literature suggesting that complex and insufficiently defined problems require more systematic paradigms. A consistent methodology, including fundamental principles, roles, tools, and the proposed timetable will support organizations to start using design thinking in professional practice. Thanks to the structured and more predictable design thinking process, more organizations will be able to implement it in their practice. Such a level of predictability also makes it easier to determine the costs of applying this methodology. We provide a unified and validated framework that can be used for both practical and research purposes.
