In today's business world, survival is no longer just about production; it is about making the "different" sustainable. This work, authored by Dr. Derya Yücel and Prof. Dr. Muhsin Halis, redefines innovation not merely as a technical term but as a strategic necessity. The book explores the transition from the "Closed Innovation" model, where businesses remain confined within their own boundaries, to the "Open Innovation" paradigm that centers on collaboration with the outside world. Presented through a comprehensive theoretical framework and up-to-date case studies—including global giants like P&G, LEGO, and Apple, as well as local pioneers like Turkcell—this book serves as a fundamental reference for professionals, academics, and entrepreneurs. It is an essential guide for those seeking to decode the DNA of innovation, adapt R&D strategies to the digital age, and escape the "commodity trap" in global competition.
