Concurrent Sessions and Crowdsourcing Process

I've been facilitating sessions that comprise 1/3 of an agenda. So the entire population would be in my session at one point, as well as all of the others, but I only ever see 1/3 of the group at a time. We're working towards the same objective in every session, so inevitably we're identifying opportunities to improve on the sessions as we go, based on observation and specific feedback.

Two things here, really.

1. Design of meeting format
2. Adjustment of meeting process

1. Dividing a group into 3 sub groups that interchange is a great idea. This way there's higher participation in each session. There are of course additional space requirements, but it's well worth the investment. Instead of one didactic plenary, you get 3 interactive workshops.

2. I'm a big believer in providing the group with options. Having a plan on how to move forward in a meeting is great, but asking the participants how they think they should move forward given the current progress can sometimes yield superior ideas. Crowdsourcing the very process is a great way to bring mindshare to process, and engage people in considering meeting design as a competency. The process today is being refined through each session as well, so that the final one is a product of meeting design conducted pre-meeting, and real-time adjustments with the benefit of the Wisdom of Crowds.

...

I guess the question is, how can the Wisdom of Crowds be better leveraged in the pre-meeting phase?
