Consider asking every attendee to bring a problem that they need help with to a meeting, instead of a report. To save time have them write it up in under 200 words and publish it at the meeting. Give a time period not to repeat the problem (we’ve seen it already) but to answer questions and take suggestions, without comment, only for consideration. This is important because otherwise you’ll have defensive debates. At the end of each you might conclude with, “Is there anything there that intrigues you and might get things more on the right track?”
