Whatever brainstorming activity you choose to employ in your workshop, ensure that they adhere to the 3 basic principles of brainstorming:

• The more, the better. It doesn’t matter if an idea is redundant, ridiculous, or downright hilarious. Encourage participants to keep them coming. This will broaden your pool of choices and also allow participants to get rid of their creative inhibitions.
• No criticism. This one goes without saying. Criticism is the death knell of creativity when it comes to brainstorming. Allow people to speak their minds freely without judgment from superiors or other team members.
• Follow the steps. Organize your brainstorming activity in alignment with your workshop goals. Also, be sure to wrap it up on time, so it doesn't hinder other parts of your workshop.^[1]
