Design management has taken a more strategic role within business since 2000, and more academic programs for design management have been established. Design management has been recognized (and subsidized) throughout the European Union as a function for corporate advantage of both companies and nations. The main issues and debates included the topics of design thinking, strategic design management, design leadership, and product service systems. Design management was influenced by the following design trends: sustainable design, inclusive design, interactive design, design probes, product clinics, and co-design. It was also influenced by the later management trends of open innovation and design thinking.
