<p>More than the hour on the clock. The real bill is the rework that follows when someone builds from the wrong version.</p> <p>Many teams lose about 11 hours a week working out which model version is current. Count the people in that loop and the hours stack up quickly. Then add the cost of what slips through: a clash caught in the model costs about $50, and the same clash found in the field costs $5,000 to $50,000.</p> <p>To see your own number:</p> <ul><li>Count who spends time asking which file is current.</li><li>Add the time spent in meetings that exist only to find out what changed.</li><li>Add the time spent reopening issues that were marked done without proof.</li></ul> <p>BidLight removes that loop. Each publish is a versioned snapshot with its own files, author and milestone, and any two revisions compare element by element. The comparison takes about 15 minutes instead of a 90-minute meeting.</p> <p>You read the answer instead of rebuilding it.</p>
