What is Work Order?
Work Order
Telling the shop floor what to make and how many pieces to make.
What it means
A work order is a production order given by the office to the shop floor. It contains information about which item to make and how many to make. The shop floor moves based on these instructions.
When you issue a work order, the system calculates the required materials using the BOM. If you don't have enough materials, you won't be able to start even if you give instructions.
At the pen factory
On the first day, work order W-1101 for black ballpoint pen 100 pens is issued. It was in a "material shortage" state due to a lack of black refill, but changed to "standby" when the refill arrived on the third day.
Why it matters
Without instructions, the shop floor doesn't know what to make and how much to make, and the office doesn't know what is being made.
How this differs from Production output
The work order is “make it” and the production output is “made it.” By comparing the two, you can see how much progress has been made and whether there are any strange inputs.
