A change is closed only when every task is Done and the ERP or PLM shows the new revision active. Add your own task rows for service parts and customer notification where needed. ## Content **Intro:** Approval is not the finish line. Most of the work in an engineering change is implementation: BOM, routing, purchasing, inspection, training and documents. This tracker lists those tasks with an owner and date so none is forgotten. **Sections:** #### How to use the tracker **Body:** Start from the standard task rows and delete what does not apply. Give each task one owner and a due date tied to the effectivity date, not the approval date. Review the sheet in a short weekly meeting and update the status. Export to Excel for sharing with people who do not use your PLM. **Bullets:** - Set due dates backward from the effectivity date. - Escalate any task marked Blocked within one working day. - Record actual hours to improve future planning. - Close the change only after every task is Done. #### The standard task set **Body:** Most changes touch the same areas: item and BOM records, routings and work instructions, purchase orders and supplier notification, inspection and test plans, tooling and fixtures, training, customer or regulatory notification and service documentation. Use these as a checklist, then add change-specific items such as software loads or test program updates. #### Reading the variance columns **Body:** Hours variance shows where the estimate was wrong. A consistent overrun on BOM and routing updates suggests that the work is under-scoped or the data is messy. Actual percent of plan above 100 with tasks still open means the plan was optimistic; replan before the effectivity date, not after. #### Common mistakes **Body:** Treating the approved ECO as done, leaving purchasing and service tasks off the list, and never recording actual effort are the usual failures. Also avoid tasks owned by a department rather than a named person, since nobody feels responsible. **Cta:** If change tasks are scattered across email and spreadsheets, we can help build a simple tracker connected to your ERP data. **Faq:** #### When is an engineering change really complete? **Answer:** When the new revision is active in the ERP and PLM, all implementation tasks are done, old stock is dispositioned, suppliers and the shop floor work to the new revision, and the change record is closed with evidence attached. #### How many tasks should an ECO have? **Answer:** A simple documentation change might have five, a form-fit-function change with tooling may have thirty. Use the tasks needed to prove the change is in effect everywhere, no more and no fewer. #### Who should own the tracker? **Answer:** The ECO owner, usually a project or configuration engineer, maintains it. Each task owner updates their own line before the weekly review. #### Does it work for software or ERP changes? **Answer:** Yes. Replace the function options with your own teams and the tasks with development, testing, transport and training steps. ## Search terms ECO implementation checklist excel, engineering change task tracker, ECN action tracking worksheet, engineering change implementation plan template, ECO task list manufacturing, engineering change closure tracker, change implementation excel --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
