Drawing Revision and BOM Mismatch Agent

Drawings, BOM and models agree on revision, part number and quantity for each assembly before release.

Drawing Revision and BOM Mismatch Agent: what goes in, what the agent does and what you get

What it does

A drawing is at revision D, the BOM still calls out revision C of a bracket, and the model in the vault is at E. Shop floor questions follow. This agent compares drawings, BOM and model data for each assembly. It reads revision letters, part numbers, quantities and material notes, then lists every mismatch. For each one it traces the latest change notice to see which source is right, and writes the cause. It sends the list to the document owners as draft messages. After the owners fix their records, it rechecks the assembly. You approve any release. Edge case: a change notice that is approved but not yet effective is shown separately so it is not reported as an error.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

Read the steps as a list
  1. Assembly selected for release or weekly scan
  2. Pull drawing, BOM and model data for the assembly
  3. Compare revision, part number, quantity and material for each item
  4. List every mismatch with the source of each value
  5. Look up the latest effective change notice for each mismatched item
  6. Decide which source is correct and which is pending
  7. Engineer approves the fix list sent to ownersThe agent waits here for your OK.
  8. After owners update, reload the data
  9. Do all three sources now agree for each item?If not: return the remaining mismatches to the owner with the change notice reference. Back to step 3.
  10. Write the release readiness summary
  11. Mismatch report and release recommendation

How it decides

The latest effective change notice defines the correct revision. Anything not matching it is a mismatch, and anything pending is listed as pending.

  • Revision differs across sources: the latest effective change notice wins
  • Quantity differs by any amount: always treat as a mismatch, never as rounding
  • Change notice approved but not yet effective: list as pending, not as error
  • No change notice found for a revision change: flag as undocumented change

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Fields compared per item
  • Scan schedule
  • Which assemblies are active
  • How pending changes are shown
  • Owner contact list

What keeps you in control

It always asks you first

  • The fix list sent to document owners
  • Any release of the assembly

Hard limits

  • Never edit a drawing, BOM or model
  • Never recommend release with an open mismatch

It stops when

  • Done: all sources agree and report issued
  • Stop: undocumented change found, engineer decides

An example run

What happensFor Assembly 4410, the BOM listed bracket 4410-12 at rev C and quantity 4. The drawing showed rev D and quantity 6, and the model rev D. The agent traced change notice CN-882 effective 3 March and judged the BOM wrong. After the owner updated it to rev D, quantity was still 4, so the check failed and it returned the item. The BOM was corrected to 6, and the engineer approved release.
