You'll develop a relevant (international) network of people involved in the topic and you'll deliver a Value Creation product.
This product might involve starting a social enterprise with the aim of building sustainable housing in disadvantaged parts of South Africa. Or it might be organizing a great event in Zwolle to raise awareness of global warming. Or exploring how cities can become healthy places where everybody counts and intergenerational collaboration is encouraged. It might be anything!
But, one way or another, you'll need to create value for society and make it evident to a network of stakeholders.
