Hmmm... Is this a free or low-cost conference? I ask because attendees typically don't like paying good money for a conference and then being pitched on one's own services.

If it's low cost and it's made known in advance there will be special offers, etc, then I guess that's okay. I've never seen an affiliate share in that respect. But I have seen coaches speaking either for free or a low fee in exchange for the ability to pitch.

If you're the organizer, an easy + effective structure is for each speaker to create affiliate links for their products which pay you commission.

Then during conference, links paying you commissions are referenced on written materials + in electronic materials like PDFs, transcripts, related blog content.

Another effective technique is to offer a discount when these links are used + say these links will only be good during conference + for a few days after.

Group discussions, Role Play, Debates.

Typical structures for conferences are “Common Reasons for Poor Performance” and the multiple speakers are selling the solution. Take an example. A group of employees comes to you for help as they lack the required capabilities. In this situation, the employee simply does not have the needed capabilities to perform the job. They might not have asked for help, or they might have asked but not received it for some reason.
Improved performance will not be possible unless you can help this group of employees to acquire the needed capabilities. You may need to arrange for training programs, one-on-one assistance from another employee, or dedicated time with you to help get them to the right place.
