You can be sure that the maintenance man checked all the machines that had, and has performed all required tasks? If equipped with a mobile terminal and the machine / control points marked barcode (or even better with RFID) everything will be clear: the terminal displays him a list of works (points of inspection), including the required tasks, scanning the bar code or RFID chip uniquely identifies the presence of service engineer, including recording date and time.
The collected data are easily transferred to the PC for further processing. Requirements for quality and traceability can then enforce the use of automatic identification (barcode, DPM, RFID) on the production lines and rigorous recording information about their transactions (when, who, what part, lot / serial number, ...).
