<p>Prepare the comparisons and the owners before you go in, so every option has a trail and a next step.</p> <ul><li><strong>Baseline.</strong> Publish the current model so the meeting starts from a versioned snapshot with a known author and milestone.</li><li><strong>Options.</strong> Publish each option as its own revision, not a markup.</li><li><strong>Comparisons.</strong> For each, compare against the baseline, element by element, by category, and note which trades are reached.</li><li><strong>Open issues.</strong> Check the project view for items that a change could make worse, or close early.</li><li><strong>Owners.</strong> Know who will be asked to act on each option, and check their 6am digest load.</li></ul> <p>During the meeting, you swap between options by comparing revisions, not by rebuilding slides.</p> <p>After it, pin an issue to every element the chosen option changes, tag the owner and close each with a screenshot, a tagged user and the linked model commit.</p> <p>The preparation takes a fraction of the time that a 90-minute debate does, because the comparison is about 15 minutes of reading.</p>
