Revision order

A revision order is an order for a part that has previously been manufactured, but at a different, newer drawing or model revision than before. It sits between a repeat order (identical to before) and a first-time order (never made before): some of the prior routing and estimate may still apply, but the specific change needs to be checked.

Why a revision order needs its own cost check, not a reused number

The cost impact of a revision order depends entirely on what changed: a relaxed tolerance might reduce cost, while a tightened one or a new feature could add an operation the prior routing never needed, so a revision order can't be priced by simply reusing the old number.

Where revision-order status is identified

Identified by comparing the new revision letter or number against the revision of the part previously produced, typically via the ERP or PLM system.

Common mistakes

Assuming a revision order can be quoted using the prior order's price without checking what specifically changed; even a small revision (a moved datum, a tightened tolerance) can invalidate the old routing or estimate.

Is a revision order the same as a repeat order?

No, a repeat order is for an unchanged part; a revision order is for the same part at a different, newer revision.

Does every revision order cost more than the original?

Not necessarily; the change could relax a requirement and reduce cost, though a new or tightened requirement can add cost.

What should be checked first for a revision order?

Exactly what changed since the last revision, using the revision history, before assuming the old routing and price still apply.
