The fitter is at the machine, not at a desk

The line is down because the belt has worn through. The fitter has taken the guard off. The belt lies on the sheet metal, his hands are not clean, and the nameplate sits under a film of grease and product residue. He wipes with the back of his hand, holds the phone at an angle because the hall light reflects in the plate, and reads the serial twice. One digit stays uncertain. He reads it a third time, types it in, and the drawing of the assembly opens. He looks for the belt on this sheet. He does not look for the folder in purchasing, three halls away. The window is too short for that.

The request is made there, if it is going to be complete. At the purchasing desk, and in your inbox, it only arrives. If the drawing is not on the phone, the part becomes a sentence. The position stays at the machine.

The plate under grease and light

Nameplates on running machines rarely look the way they do in the catalogue photo. Grease, dust, an inspection sticker, an edge that was taken off during cleaning. The serial is still the best information the machine carries about itself. It has to be readable even when the light is against it. The fitter types it from the plate, or from a photo when there is no room to stand square in front of the machine. Both fail at the same place: a digit he fills in because it disappears in the reflection.

The uncertain digit is read again, not replaced by the most likely number. The most likely is often the one on the neighbouring machine, because the plates hang side by side. Many pull a hand out of the glove, because otherwise the glass does not respond. Type and year of manufacture do not replace the serial. Two machines from one year can have two sheets. The photo of the plate is evidence. The drawing that opens with the typed serial belongs in the same place.

The drawing belongs at the machine

The exploded view of this serial has to open on the phone he is already holding. Not on the computer in the supervisor's office, and not in a file whose path only purchasing knows. If the serial opens a different sheet from the machine beside it, that has to be visible. If it opens nothing, because the assembly is not yet released, that has to be visible too. An old general drawing that pretends everything is there is worse than a missing assembly.

On the sheet he taps the position. The balloon has to be hittable with the thumb, the number readable, the line to the part recognisable, even with only one free hand. The row shows the name and the part number. He compares them with the part in his hand. If they do not match, he taps the neighbouring position. An hour later he has only the memory, and the memory names the neighbour.

He sets the quantity himself. The bill of materials says how often the belt is fitted. He needs one, or the second one at the same time. A step that says "quantity later in the office" is the step in which 1 becomes 4. The quantity field has to be reachable in the same minute as the balloon.

The stop is short

A stop of this kind lasts until the line is supposed to run again. In that window he can read the serial, tap the position, and set the quantity. An account, a PDF on the network drive, and a call through purchasing have no place in this stop. What does not fit into it is created in the afternoon from memory. By then the guard is closed again.

The request has to be sendable before he walks back to the office. Sendable means serial, assembly, position, part number, name, quantity, and an address for your quote. A remark about the shift or the gate must not replace the position. If the number is in the fields, it survives the walk. If it is only in his head, on the way it becomes "the part from the belt". A password that only purchasing knows shifts the request there. Purchasing is not standing in front of the open belt, and rarely circles a position on a drawing.

The PDF in purchasing does not help him now

In purchasing, the exploded view often lies as the PDF from the order the machine came with. It is complete in the filing and unreachable during the stop. The fitter does not know the folder, the computer is locked, or the path applies to the type and not to the serial. By the time he would have marked the place, the guard is closed, because the line is supposed to run again.

Purchasing sends the file on later, unmarked. You receive a PDF and a sentence. The PDF proves that the drawing was delivered once, not which position is meant today. A plot on the door helps only until the next change. If the released sheet for the serial differs from it, the sheet on the phone has to win. Otherwise he reads out the old number.

The request goes out before the walk back

As long as he stands in front of the machine, he can compare balloon and part. Once he leaves, the choice in his head shrinks. In the office, purchasing turns it into a tidy text. Each stage can lose the position number. A request that is already on its way before he changes halls no longer has those stages between the number and you.

Sending sits on the same phone as the drawing. Serial, assembly, position, part number, name, quantity: that is the line you read. The quantity is his. The part number comes from the released bill of materials, not from a label on the old belt that may belong to the predecessor. If he cannot do it, because the assembly is not released or the serial stays illegible, the phone call is the honest path. He should then be able to say that the sheet was missing.

Inside sales writes the quote afterwards

What he sent is not an order and not a price. Partmira takes no payment, writes nothing into the ERP, and states no stock. The request arrives as email or as CSV. Your inside sales writes the quote, with your price and with the lead time that stores or production can give. On the drawing, prices are on request.

Whether the part is in stock, has to be made, or a superseded number is replaced by another one, you see in the file and in the stores. That check does not belong on his phone as a green or red mark. You make the promise in the quote. He names the part while he is standing in front of it. You price it and name a delivery date once the request line has arrived. The purchasing desk is the right place for the price and the wrong place for the position number.
