Room and unit identifiers connect production kits with their eventual installation location.

Room and unit identifiers connect production kits with their eventual installation location. Keep them stable and map any site numbering changes explicitly. Similar units make a reliable identity more important, not less.

## Establish the map

- Record building, floor, unit, room, and cabinet references at the level needed.
- Distinguish unit types from individual physical units.
- Preserve the mapping when site labels or drawing references change.
- Carry the identifiers onto kits, packages, manifests, and punch items.

## A mix-up example

Two hypothetical units share the same kitchen type but use different finishes. A label showing only the type cannot prevent a swap. Include the actual destination and the specification that distinguishes the assemblies.

## Test the handoff

Ask dispatch and installation to identify a package from the same record. Resolve naming differences before repeated units are packed in volume.

## How Millbase can help your shop

### Make production conversations specific

A woodworking schedule is easier to review when the team can see the work already recorded. [Millbase Floor Pulse](https://millbase.ca/#floor-pulse) shows active workers, projects, workstations, and elapsed time. Pair it with [project records](https://millbase.ca/#projects) to discuss a delayed cabinet order with the people and work behind it, and compare logged labour with the estimate.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Who is working on this project, at which workstations, and how many hours have been recorded?”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Use the breakdown to prepare the next production conversation. Current activity and recorded hours are evidence for planning; they do not by themselves prove that an assembly has passed inspection or is ready to ship.

## Frequently asked questions

### Can unit type replace unit number?

No. Type describes a design pattern; unit number identifies the destination. Use both when both affect the work.

### What if the site renumbers rooms?

Keep an explicit old-to-new mapping and communicate it to every affected team. Do not silently rename historical records.
