<p>A change is defensible when you can point to the element it affects, the revision it came from and the person who owns the follow-up.</p> <p>Most proposals fall apart because nobody can explain what they will touch. BidLight ties each change to the model:</p> <ul><li>The option is published as a versioned snapshot with its author and milestone.</li><li>A comparison against the baseline lists what was added, removed or modified, by category.</li><li>Issues are pinned to the elements concerned, with the sheet and revision attached.</li><li>Each has a tagged owner and a place in their 6am digest.</li></ul> <p>In the room:</p> <ul><li>You show the comparison, not a description of it.</li><li>You answer why quickly, because each point links to an element.</li><li>You test alternatives. Publish another option and compare it too.</li></ul> <p>It turns a defensive meeting into a working session. And once a decision is made, the issues it creates close only with a screenshot, a tagged user and the linked model commit.</p>
