Log Sheet Data

Our industrial wastewater treatement operation has two shifts on weekdays and one shift on weekends and holidays. Our various log sheets have columns for data logging and operator initials for both shifts. During weekdays all columns on the log sheets are filled in by both shifts. On weekends and holidays only one shift works, so only the columns for that shift are filled in. A dash is put in the spaces in the empty columns where no shift was working and no data collected.


One of our managers is insisting that rather than dashes in the empty columns, to represent no one working and no data collected, that we should put in zeros.


Everyone else believes that zero is a measurement and represents a false reading.


This difference of opinion is escalating into a major issue.

Any experience you can relate or advice you can offer would be greatly appreciated!

Why not a space at top or bottom of shift column with a notation that plant was unstaffed during that shift?

Or use N/A notation in data entry space, if not too many spaces. The fewer places to enter "Unstaffed" notation the more likely it will be accepted.

I agree with you, Rock.  A zero is a zero which is a value.  A line or N/A is best.
