Ground Rules Short session (20 minutes) Create ideas in silence Multiple rounds

Idea Trigger Method Phase I: Idea Purge Phase The objective is declared. Many ideas written rapidly on sheet of paper. There is a relaxation break after two minutes. The process continues for another minute.

Idea Trigger Method Phase II: Idea Trigger Phase Leader calls each member for their ideas. Team members cross out shared ideas. Each idea as read may trigger other ideas in other members who write them down quickly on a second page. After the first round, the members repeat the reading process for the second sheet and more until no new ideas are triggered.

Idea Trigger Method Phase III: Compilation Members compile and classify ideas into a master list and distribute it.

Afterwards Work alone to create more ideas. Meet and selects promising ideas. Promising ideas are developed in more detail listing pros and cons.

Idea Selection Team meets and selects one design to be engineered. Team members identify critical sub-systems and hold brainstorming sessions on such sub-systems.
