Understanding Data Collection

In a traditional shop floor we can see manual data capturing methods using LOG BOOKS and PRODUCTION REPORT BOOKS.

LOG BOOKS are generally used to record details of major events in the production floor during a shift like major break downs, root cause analysis and any personnel related appreciation and observation.

PRODUCTION REPORT BOOKS are designed with columns and rows and headings provided to capture certain productivity and quality related information in table form.

Process of capturing data is, for the operator to write down the information in a pre decided frequency. The book would also be handled by  patrol inspectors to write down rejection information.

In some companies quality inspector maintains a duplicate record on rejection related information and operator fills in the same data in PRODUCTION REPORT BOOKS. It is quite certain that information in both locations do not match, resulting in a discussion later as to which is genuine

All the data is tabulated and keyed in to an excel sheet at the end of the shift. This is usually done by the shift supervisor before he leaves the factory after the shift. 

Automatically Collected Data is so accurate and robust that it captures exactly what is happening on the machine.  As the data is captured through electronic pulse that is generated when a unit is produced and this pulse could not be duplicated or restricted manually, there cannot be any errors. There counts are stored electronically and immediately processed to produced realtime on line analysis.
