<p>Because the model shows the state, not the change. People spend the meeting working out what is different since last time and who knows about it.</p> <p>The time goes to five places:</p> <ul><li><strong>Which version.</strong> Teams lose about 11 hours a week working out which model is current.</li><li><strong>What moved.</strong> Without a comparison, you walk the model hunting for differences.</li><li><strong>Who owns it.</strong> Issues scattered across email and markups have no clear owner.</li><li><strong>What is still open.</strong> Nobody holds the list.</li><li><strong>Whether it is really fixed.</strong> Items marked done without proof come back.</li></ul> <p>BidLight cuts each one. Every export is a versioned snapshot, revisions compare element by element, issues are pinned to the element with a tagged owner, and closure needs a screenshot, a tagged user and the model commit.</p> <p>The comparison takes about 15 minutes instead of a 90-minute meeting. Walk in having read the 6am digest, and use the time to decide, not to discover.</p>
