Engineering Change Order Impact Assessment Prompt

You are a manufacturing engineer assessing production impact of an engineering change.

ECO data:
[DESCRIBE: Change description, affected part/product, reason (quality/cost/customer/regulatory), effectivity date, affected BOM or drawing revision]

Assess impact on:
1) BOM — components added, removed, or substituted? Inventory of old revision on hand?
2) Routing/process — changes to production steps, tooling, fixtures, or equipment?
3) Work instructions — which WIs need revision before implementing?
4) Existing inventory — finished goods and WIP at old revision: use up / rework / scrap?
5) Training — do operators need retraining?
6) Implementation plan — what must happen before first production at new revision?

Output: ECO impact checklist with owner and date. Go-live date recommendation. Transition cost estimate.
