I connect the valve on the test bench to the record a customer, an auditor or a plant engineer later has to rely on.
The first planning system I trusted was a magnetic board in the production office of Ostrinder Pumpenbau in Bremen. I joined in September 2001, three months after completing a diploma in industrial engineering and management at Technische Hochschule Vehrlingen. The company built centrifugal pumps for ships and waterworks, and my job was to sequence machining orders around castings that did not always arrive when the purchasing system said they would. The board was crude, but everyone in the room could see it and everyone corrected it. The planning module on the screen beside it was more precise and much less believed.
A shop-floor record is written by someone with a valve in front of them and a shift to finish. If the system asks for a value at the wrong moment, or twice, it will be filled in later from memory, and the record will look complete while proving little. I design from the bench outwards, and I would rather connect fewer things properly than many things that nobody believes.
