Erich Kolenaty created a photo presentation on the one day OST event in
Würzburg/Germany (2013) that HO mentioned with 2108 participants.
232 issues were presented and dealt with in 3 phases (starting times at
10:15, 11:45 and 13:45) which meant 77 breakout spaces. Many of the
breakout spaces were set up by the participants... look here

There is also a 78 minute film on this event, including the English and
German version of the introduction by HO and mmp, interviews with
participants, facilitators and sponsor, available here

If Peggys rule of thumb would have been applied (20% of the people post
issues in large groups) there should have been 421 issues. At the
Würzburg event nobody imagined 232 issues. But 232 issues were easily
dealt with by the 2108... the only explanation I have for that is the
magic of the force of selforganisation.l
The rule of thumb mentioned in the "mini spec" that Robin Muretisch
posted "... 3 out of 10 participants will post a session" would have
meant 632 issues in Würzburg.
So much to the rules of thumb.
My experience is that the number of issues posted is not only a factor
of the number of folks attending but also has to do with the length of
the event.
With smaller groups the number of issues can be the same as the number
of participants and even more if it is a "regular" 2,5 day OST event
where additional issues are posted during the event.
Another factor is that participants vary greatly in the number of issues
each participant offers. In some cases there will be participants that
offer 2 to 10 issues and others dont offer any.
The ressource that Lori Palano remembered to have seen was a graph with
two parameters (number of participants and number of issues) that was
prepared by someone in the team that set up the event with 2108
participants.
Basically, it showed a curve that rose steeply and then tapered off to
almost a straight line... meaning that in general the number of issues
rose inversely to the number of participants, or, the larger the group
the smaller the number of issues per participant.
I am sure someone among us has that graph buried in a file.
I wonder what additional parameters other than than number of
participants and length of the event would have to be considered for a
more reliable tool to predict the number of issues to be expected at an
OST event.

And then there was the time when Michael Pannwitz and I had 2108
participants… And I think we ended up with 175 Groups. We grossly
under-estimated (75) – but fortunately you can add groups as many as
you need. The People are always right, and they will claim the space
they need. Facilitators are only guessing – and then just get out of the
way J

Hello all
A number of years ago I seem to remember a resource shared on this list
that calculated an average number of breakout groups that tended to show
up according to the total number of participants based on the cumulated
experience of this community. Does this ring a bell with anyone? I think
it was an excel sheet. I'd like to find it again, but so far my
searching hasn't lead to anything.
Here's hoping!
Lori
