Part approval belongs to the tooling rather than the shop
Part approval covers this part, on this tooling, in this plant.
The tooling is your property, and it is bolted into somebody else's press.
Better is weighed against the change.
An alternative has to beat the incumbent by more than a tool move, a bank of finished parts built to cover the weeks nothing is made, and a full approval run again from the start.
Every part carries its own approval
The toolPart approval is a package of evidence for one part, made on one set of tooling, in one plant, by one process, closed by a warrant your customer signs.
A shop holding approval on forty parts holds forty separate approvals, and none of them travels.
The published submission requirements say what re-opens one.
New, additional or modified tooling.
Tooling or equipment transferred to a different plant location.
A change of supplier for a part, a service or a process.
Product made after the tooling has stood inactive for a year.
Any one of these re-opens the submission, which then runs again from the beginning.
You own the asset and the incumbent holds it
The arrangementThe automotive quality standard requires customer-owned tooling to be permanently marked, so ownership is visible on the tool itself.
The buyer owns an asset it does not hold, and the incumbent holds an asset it does not own while running the system that identifies, stores, retrieves and maintains it.
That is the arrangement itself, written into the standard both parties are audited against, rather than a description of lock-in.
One Tier 1 publishes what moving a tool costs: advance written approval before anything moves, an exit approval from the plant it leaves, a full submission approved before any production material ships from the new one, and a bank of finished parts built ahead of the move so the receiving line does not stop.
Somebody funds that bank, stores it and carries it, because the receiving line cannot stop.
A second source is a capital event
The arithmeticAn alternative is weighed against the incumbent plus a tool move, a bank of parts, a full re-approval, and the risk that the re-approval fails.
Once the tooling has been cut, an alternative rarely clears that arithmetic.
Three people carry it, and none of them is measured on having found a better supplier. The buyer is exposed by change, the person signing the warrant is exposed by approving it, and the plant manager is exposed by what change does to a Tuesday.
The alternative is therefore sourceable in one window, at sourcing, before tooling kickoff, while the tool is still a drawing.
That window opens once per part, often years apart. The shortlist that matters was written before anybody knew they had a problem.
An approved list records who was known in the weeks before a tool was cut, which is a different thing from a record of who is capable.
ConvergX is not in the approval chain
The boundaryConvergX approves no part, signs no warrant and holds no standing in your quality system.
The advance planning, the submission, the run at rate and the capability study all stay where they are, run by the people who run them now.
ConvergX finds a company that has run this class of work in another industry, and asks who it is, what it has actually run, at what rate, for whom. Then a person at ConvergX decides whether the two sides should meet, and brokers the introduction.
Your gates open on schedule, on a candidate somebody was willing to put their name beside.
This sector proves a line will hold at rate before it makes the first piece.
Advance planning, the initial process study, the run at rate and the capability index are one evidence package, and what it says is that this line will make this thing this many times to this tolerance, before it has made one.
NATO's Defence Production Action Plan, approved by Allied leaders in June 2025, states an aim of opening opportunities to companies including non-traditional suppliers and small and medium-sized enterprises. That is public policy, noted here as ground ConvergX works on and not as anything ConvergX built.
The capacity being asked for is machining, stamping, fabrication, electronics assembly and process work run to a proven rate. Most of the plants that do it have never bid a defence contract.
It runs the other way too. Making forty of something and supporting it for thirty years is a different discipline from making four hundred thousand of it in a year, and configuration control, obsolescence management, controlled-goods handling and sustainment after the tool is dead are things a high-volume plant has never needed. Registration is the visible part, and no certificate confers the rest.
A cold approach cannot be timed to a tooling kickoff
TimingThe window opens before anyone announces it, and a capability holder has no way to see it.
A sourcing organisation cannot run a market scan at every programme either, because the scan costs more than defaulting to the incumbent.
The Congress is three days in a room once a year, which does not depend on catching the window. ConvergX publishes that attendees are individually vetted, and that proof of ability to directly influence business direction is required to be considered.
One requirement at a time is the shortest thing ConvergX runs, and the question it answers is who could hold this part, at this rate, starting at the next kickoff, and is in a position to take it on.
Xpand runs on a longer clock than a single requirement, nearer the shape of a company entering a market it has never supplied.
