Brainstorming

Brainstorming is an Ideation method where a group of people will attempt to generate new ideas and different solutions to a given problem or context by removing inhibitions and suspending critical judgement about their quality or adequacy.

The process  starts with the goal of creating  as many ideas as possible, and to explore different and unexpected ideas and solutions (the divergent stage) and following that, the group can then evaluate, select and refine some of for further analysis and development.
