You are organizing an exploratory in-person meeting with engineering representatives from a dozen manufacturers around the world to discuss updates to a technical standard that all the companies’ products must adhere to. The representatives have a wide range of firmly held opinions on the subject, because the changes could help some companies and hurt others. They can’t even agree on what should be addressed in the first meeting, so you need to develop a minimum level of consensus on what should be on the agenda. Which combination of media and channels would you use to move the conversation forward and finalize the agenda? Each company has one representative, and any discussions need to be kept confidential.
