Cycle-time drag and stage attribution model

Every day a home sits in a stage beyond what the same crew has already proven it can do, traced to the stage, the trade and the cause that produced it. Fix the cause once instead of carrying the interest on every home that follows.

Evidence grade

Proven throughput and planned duration are two different numbers

A home is marked "on schedule" against the plan target. Nobody compares the plan target to what the same crews have already proven they can do on their fastest homes — so the gap between proven and planned, and the larger gap between planned and actual, both go untracked until the closing date.

Every stage, every home, compared to the crew's own demonstrated best. The drag is traced to a specific cause — a crew, a hold, weather, a scope change, or site sequencing — so a supervisor can act on the worst-offending stage this week, not discover it at closing.

28 days · addressable

Trade sequencing and release policy

Waiting on a full multi-trade sign-off — framing, drywall, interior finish — before releasing the next stage. The release-policy control targets this directly.

7 days · partially addressable

Inspection holds and site sequencing

Municipal inspection wait times and lot-access order. Plannable around, not eliminated.

8 days · not addressable

Change orders

Legitimate scope changes. Tracked in the ledger, never claimed as recoverable.

4 days · not addressable

Weather

Priced separately in the weather and seasonal exposure model. Not double-claimed here.
