Method
From the book on the podium to the hour in the room.
A study is a sequence of ordinary tasks. The order matters because a chart drawn before the codes are named will repeat the procedure instead of the shift.
-
Name the line
The first letter says which line, cell, commodity, or characteristic is in scope. "The whole factory" is not a scope we can price. If two lines share a book, we still pick one window and one subject, then quote the second.
-
Agree the dates
Ninety days is the usual window for a Plant Quality Picture. A shorter window is welcome when the die changed and the older weeks would only blur the new tool. Dates outside the window stay outside.
-
Copy the pages, leave the originals
We photograph or take copies. Original books remain at the plant unless the manager asks us to carry them, in which case they return with the folio. Pencil is photographed from the side, under a low lamp, because a flash from above wipes the groove.
-
Two readers, then a sample check
Two readers enter figures from the photographs. A third person checks a sample of rows against the photo. A mismatch sends that page back. We would rather delay a chart than brief a digit that was misread.
-
Draw on paper first
The first picture is on paper at the long table in Wang Thonglang. Codes that appear in the book and not in the procedure are listed in a margin, not forced into the official name. Unread rows are a blank, not a zero.
-
The plant checks the words
A draft goes back for names, code spellings, and the unit of scrap. This is the revision included in the fee. A request to join two codes the shifts use differently is a conversation, not an automatic edit. Siriporn's solder codes were split for that reason.
-
The supervisor speaks before we do
At the briefing the person who owns the line speaks first, so the room hears the plant's account before ours. We then walk the folio: what was written, what was unread, and the three questions we think the room can answer without a new gauge.
-
The folio stays
The cloth folio remains with the quality manager. We keep our working photographs at the office for the retention period in the privacy notice, and we do not put a plant's sheets on this website.
Before we arrive
Have the book, the scrap tickets or hold tags, and someone who can read the night shift's hand. If the sheets are only ticks, say so. If a gauge has been sticking, say so. Both facts change the picture, and both are cheaper to hear in the first letter than in the briefing.
