If you have the option, the most effective thing you can do is ensure that the person responsible for the minutes is not an active participant in the meeting. The person who writes the minutes wields the greatest power in the room, because their version of the proceedings is the official record. As such, this person should ideally be on "your side."

For example, I'm a planning and engineering consultant for large public works projects. As a rule, I never go to a meeting without someone else from my firm, so that one of us can actively participate and the other can take notes. Even if I'm not taking detailed notes, I still write down EVERYTHING that I (or my firm) am responsible for so I can verify the action items in the minutes are correct.

Which gets me to action items, which are to minutes like corned beef sliced just so is to a reuben. When you write the minutes, list the action items before the actual proceedings of the meeting, and write them [duh] as actual actions, with dates if possible: "Merlin will clone our secret flying pig by noon next Friday."

If you don't have the luxury of separating your active participation from note-taking, at least make sure to capture ALL commitments made during the meeting and memorialize them as action items. The actual notes, like "DB observed that pigs can't fly," are important, but pale in comparison to action items.

Good luck!

[And Merlin, I'll be on vacation on Friday, so just make sure the new pig is ready first thing Monday morning, 'kay?]
