  Value streams require real time data collection in order to control them. This is often done automatically by the equipment itself but in some occasions it must be done manually.  In spite of the high-tech of our shop floors you can still see pencil and paper data collection being used. https://youtu.be/C7chwW_cXbc Unfortunately, detecting aspect defects is often difficult to automate even with AOI (Automatic Optical Inspection). When an operator is required to inspect we need a method to enter the results into the system. Line incidents, change of critical process parameters, etc. also need to be reported the moment they take place. Pencil & Paper Reporting The method still widely used in this 21st century is: The operator hand writes the defect data on a form Forms are collected at the end of the shift A clerk types the forms contents into the system at a later stage The engineer analyses the results and takes corrective actions well after the data was entered. Thi...

  Data collection is not for free. While an operator is recording data, he/she is not producing. In general variable data such as a speed, temperature, etc. requires some sort of equipment to measure it and therefore it is more expensive to collect than attribute data: Pass/Fail, On-time/Late, etc. Time is a key variable in any process which can automatically be collected by any PC, Portable, Tablet or Smartphone, therefore it does not require any additional measuring equipment. Entering a date or a time manually into a terminal is prone to multiple typing errors which if undetected can distort all subsequent key metrics. If data is collected on paper and then typed into the system at a later stage, apart from the waste of this operation, the errors might be difficult to recover. If we are able to simplify the data recording operation, the operator can report in real time all incidents or data entries, in which case the data collection application can automatically associate a Tim...
