Workshops can be very exhaustive because of a wrong planning and being confronted without aggregating the content and being confronted with a full range of knowledge. Activiation is the key factor of a good workshop! Work with people and let the people work! For me there is a 70 / 20 / 10 rule. 70 % of the workshop the people should listen to the content. 20 % of the workshop time people should apply the knowledge and 10 % of the workshop time people should have the oppurtinity to think and reflect on the content.
