It depends!

• For online use, you would need each participant to create an account. Unless they can join by groups of two or three from different remote locations.
• For onsite use, we usually provide one device for 1, 3, 6 or 9 participants. It depends on what you wish to achieve.

One device for each participant

Pros:

• When you need strictly anonymous inputs or votes.
• Very effective with small groups as long as you alternate individual work on the device and group discussion.

Cons:

• More expensive
• Technology is ubiquitous and may obstruct group discussions

One device for 3 participants

Pros:

• Fosters discussion within the group of 3
• Perfect for collaborative processes: participants can read, enrich, score and assess others’ ideas

Cons:

• Individual vote is not possible

One device for 6 or 9 participants

Pros:

• Cost effective
• Good for bottom-up processes: Q&A, qualitative feedback...

Cons:

• Individual vote is (still) not possible
• Some participants in the group cannot see the screen, therefore making it difficult to read, enrich, score or assess others’ ideas
• Groupthink bias
