Advantages

- All the advantages of the simple single-room setup also apply to this one.

■ It accommodates a large number of observers.

■ Because so many observ ers can attend, debriefings between or after sessions can be more useful than when a smaller number attend.

- You may not have to record sessions because everyone who wants to observe can.

- With present, engaged observers, you can gather notes and insights from them more easily.
