The book "Knowledge, Complexity and Innovation Systems" offers a comprehensive analysis of the complex interactions between knowledge, innovation, and the systems that support these processes. It highlights the idea that innovations do not arise in isolation but are fostered through the interaction of various actors and their specific characteristics. These characteristics are consistent across different levels, such as national, regional, and sectoral systems. The work addresses the challenges that arise from the generation of knowledge through individual and collective interactions and examines how organizations develop new products and techniques. A central concern of the book is to understand the mechanisms of knowledge creation, particularly regarding the mobilization and transformation of tacit knowledge. It is a valuable contribution to the discussion on knowledge management and innovation processes in organizations.
