In short, historically we could summarize design management development in five phases. From design as a function from 1940s till 1950s, design as style from 1960s till 1970s, design as a process from 1980s till 1990s, design as a leadership from 1990s till 2000s, and as design thinking from 2000s up front (Borja de Mozota and Young Kim, 2009, p. 67-68).

I’m exploring & researching the inter-dependence of the business model innovation with design thinking. You may wish to hire me as a Business Design Coach or Senior Lecturer in Design Management or as a Key-Note Speaker at your next event.
