People Before Methods
The only working tool you should be committed to – people.
Today I participated in a design thinking workshop to support a friend's sister who's working on her bachelor thesis. In a group of around 20 people we had to come up with an idea of how to reuse a youth hostel in a rural area. A quite interesting task in a time of location-independent acting. After a day of working with people of different professional backgrounds, from free artists to freelancers, we had to give feedback. Some negative critics mentioned that the process of rapid idea iteration was too packed with methods. Often participants in this kind of workshops feel disrupted by rapid idea iteration or are not used to switch between a wide range of methods quite fast. Obviously they shouldn't have to. The organizers of such events in general want to stick to the plan as much as possible because it brings control. In addition they cannot be involved in any kind of group activity thanks to strict and required timeboxing. That's the reason why they often miss out on a lot of vivid and focused interactions between participants due to a special method or not. There are too many unknown variables you can ever really cover during a workshop which could bring the whole creative process to a full stop.
Accelerate the process of idea iteration by offering a small set of methods for each stage of the iteration so you are more flexible to handle the unexpected and stick to a method if participants feel comfortable with it to tackle the following tasks on the way to a clear idea.
