What is a service jam?
Copenhagen Service Jam provides you with the opportunity to connect and work together with like-minded people from diverse backgrounds. So no, you don't have to be a service designer to be join the event, as long as you have passion in creativity and have an open, enquiring mind.
As a participant, you will go through the whole design process in one weekend. This gives you the opportunity to shape a concept from nothing to something, and possibly experiment with methods that you normally don't use in daily setting.
What is even cooler is you get the chance to have your concepts reviewed by experts within the area, and have them presented to the world.
