Rework records help a shop distinguish original production effort from the cost of correcting a problem.

Rework records help a shop distinguish original production effort from the cost of correcting a problem. Keep the work attached to the job, but identify its reason and affected operation. Otherwise future estimates may absorb avoidable errors without explaining them.

## Record the correction

- Identify the job, component, defect or change, and discovery stage.
- Separate customer scope changes from internal errors and supplier issues.
- Capture replacement material and additional labor in the same review.
- Record the corrective action and who confirms completion.

## An illustrative review

A door replacement takes one material sheet and three labor hours. If the cause was an approved design change, the estimating lesson differs from a drilling error. The quantities alone cannot tell the team which process to improve.

## Look for patterns

Review repeated causes by job family and station. Avoid ranking individuals without accounting for task difficulty, detection responsibility, and who inherited the problem.

## How Millbase can help your shop

### Bring job-cost reviews back to the recorded work

Use [Millbase project tracking](https://millbase.ca/#projects) to keep a cabinet job and its sub-projects together, then compare estimates with recorded labour and material costs. [Insights and reports](https://millbase.ca/#insights) help the team inspect the people and workstations behind a total and export supported results for the next review.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Compare this project’s estimated and actual labour, then break the logged hours down by workstation.”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Check the date range, job scope, and recorded inputs before changing a quote. Keep the accounting treatment of overhead, tax, and revenue in the appropriate financial process; a shop-floor cost breakdown is only as complete as the inputs recorded.

## Frequently asked questions

### Should rework be hidden from the customer-facing schedule?

The internal plan needs the real recovery work and resulting timing. External communication should follow the project's agreed process.

### Is all rework preventable?

No. Focus on understanding causes and reducing repeatable errors rather than assuming every correction signals poor performance.
