Define the request and decision owner<\/h2>\n
Start by recording the requester, reason and affected program. Changes may come from a customer drawing update, component obsolescence, a manufacturing proposal or correction of an existing definition. List the affected part numbers, assemblies and controlled records, such as drawings, BOMs, wire lists, pinouts, labels, test programs and inspection instructions.<\/p>\n
Keep a request separate from an approved change. A supplier may propose a substitute or process adjustment, but the proposal stays pending until the authorized customer or design owner makes a decision. Record reviewers, approval date and any conditions. If engineering, quality, purchasing or the end customer must review the request, assign those decisions before setting effectivity.<\/p>\n
Assess fit, function and verification impact<\/p>\n
![\"Two](\"https:\/\/jinhaiharness.com\/wp-content\/uploads\/2026\/11\/wire-harness-change-configuration-comparison.jpg\")
<\/figure>\n<\/h2>\nCompare the current and proposed configurations feature by feature. Review connector and terminal interfaces, circuit mapping, wire construction, branch geometry, protective materials, labels, packaging and installation. Ask whether the change affects mating, service access, fit, function or interchangeability. Determine whether existing inspection and test methods still provide suitable evidence for the revised design.<\/p>\n
Record the evidence considered and the conclusion for each relevant area. If the impact is uncertain, leave it open with an owner instead of assuming the change is minor. A changed feature may require a sample or other verification, but the project design authority must define the actual scope. The sample approval checklist<\/a> can help structure that review.<\/p>\n
Set effectivity and disposition existing material<\/p>\n
![\"Separated](\"https:\/\/jinhaiharness.com\/wp-content\/uploads\/2026\/11\/wire-harness-change-effectivity-material-review.jpg\")
<\/figure>\n<\/h2>\nDefine when the new revision becomes mandatory using a boundary the buyer and supplier can identify, such as an order, date, lot, serial range or other customer-controlled event. State whether the boundary applies to procurement, assembly completion or shipment, and specify the program or part family covered.<\/p>\n
Document what happens to open orders, work in process, finished goods, supplier-held components and service stock. Options may include use as is, segregation, rework, return or scrap, but the responsible authority must select and approve the disposition. If old and new configurations can overlap, state the approved period and how each will be labeled or traced. Never assume old stock may be consumed or discarded without an authorized decision.<\/p>\n
Release a complete controlled package<\/h2>\n
Before implementation, confirm that all affected documents carry compatible revisions. Depending on the change, this may include the drawing, BOM, wire list, pinout, test map, work instruction, inspection plan and label artwork. Distribute the package through the agreed document-control route, mark superseded files and request acknowledgement from the people responsible for quoting, purchasing, building and inspection.<\/p>\n
Ask the supplier to identify the first order or lot built to the new configuration and the method used to distinguish it from prior production. Update fixtures and inspection instructions when their acceptance basis changes. Keep the acknowledgement and first-build reference with the change record.

Handle changes during quotation<\/h2>\n
If a revision changes while suppliers are preparing quotations, send the same approved package and summary to each bidder. Ask suppliers to identify any technical or commercial effect on the earlier offer, especially when connectors, wire, routing, quantity basis or inspection requirements change. Make the purchase documents reference the revision used for selection, and keep unresolved decisions visible as open items with an owner and due point.<\/p>\n
Do not edit a released file in place without a revision record. Preserve the superseded package according to the document-control process so the quotation and production history remain clear. JinHai\u2019s custom wire harness service<\/a> describes general manufacturing capabilities; project-specific substitutions and approvals still require written agreement.<\/p>\n
Verify implementation and close the change<\/p>\n
![\"Engineer](\"https:\/\/jinhaiharness.com\/wp-content\/uploads\/2026\/11\/wire-harness-change-implementation-verification.jpg\")
<\/figure>\n<\/h2>\nIssuing a revised file does not by itself complete the change. Confirm approvals are recorded, affected documents are released, obsolete work points are addressed, inventory disposition is complete and the first-build evidence is collected. If the change is conditional or staged, keep it open until the conditions are met or replaced by an authorized decision.<\/p>\n
