<p>Yes. Early coordination is the cheapest coordination. A conflict resolved in a rough model costs far less than the same one found later.</p> <p>A clash caught in the model costs about $50. Found in the field, $5,000 to $50,000.</p> <ul><li>Publish early and often. Every publish is a versioned snapshot, so a rough model becomes a baseline you can compare against.</li><li>Compare each new revision to the last. As the model fills in, you see what moved, element by element, by category.</li><li>Pin issues to elements as they come up, with the sheet and revision attached.</li><li>Tag owners and let the 6am digest keep items visible.</li></ul> <p>Be realistic: a rough model only shows what has been modelled. Missing elements will not appear in a comparison, so note what is still to come and check it as it arrives.</p> <p>Starting early also builds the habit. By the time the model is complete, the record already shows who decided what, and when.</p>
