Design thinking is a complex concept that has no single agreed upon definition. It can refer to both the cognitive processes of designers ("designerly thinking") and the use of design methods by non-designers to address problems ("design thinking"). While design thinking aims to provide a framework for innovation, some argue it risks oversimplifying design or being used ineffectively by those without sufficient skills. For design thinking to achieve its potential, closer collaboration is needed between fields like management, design, and innovation research.
