Interdisciplinary collaboration
“The disciplines need each other to find solutions. You will have to cross the boundaries of your own discipline and act in disciplines where others are specialized in. Mutual influence determines the content and details of meaningful and desired solutions.”

In multidisciplinary collaboration everyone keeps thinking and working from his own field and expertise. There is a shared problem that is looked at and translated from the various disciplines. In transdisciplinary collaboration the participants try to work from thinking and working methods of different disciplines than their own. They use each other's medium, technology and expertise. By optimally mixing these, new 'interdisciplines' or working fields can arise.
