This book is an introductory text on design science, aimed at helping both master's students and researchers to structure, conduct, and present design science projects. It is based on established methods of design science as well as current works on the presentation of design science studies and ethical principles for design science. Additionally, it offers innovative tools for visualizing results, both in the form of process diagrams and in canvas format. While the book does not require prior knowledge of design science, it provides readers with a comprehensive understanding of the subject and enables them to delve into much deeper details, thanks to extensive sections on further literature. Design science in information systems and technology aims to create novel artifacts in the form of models, methods, and systems that assist people in developing, using, and maintaining IT solutions.
