Brainstorming sessions can take many different forms, however here we adopt a method to use standardised templates to be filled out by participants answering one or several rounds to given challenges. Facilitators lead the grouping of ideas, which in a second step, can be matured (see Mature Your Ideas).
With these two types of brainstorming activities, you will systematically, simply and effectively transform questions and challenges into ideas. Here, there are examples of two different approaches: the open and the closed brainstorming. In both options, you can benefit from putting together a team with different professional competencies to get as many different ideas as possible.
