What is Common Code?
Common Code
A pre-determined selection list that can be used together on multiple screens.
What it means
A common code is a list of reasons for defects, reasons for downtime, and things that must be selected from fixed values, such as units. A box will appear on the screen to choose from.
If you write it down by hand, the same thing will be written in multiple ways and cannot be combined. If you pick them from the list, you can count them like "16 jammed springs."
At the pen factory
The reason for the defect was separately written as “spring”, “spring jammed”, “spring defective”, and “spring”. Turn it into a list of things to pick on day 22.
Why it matters
Only when you can count the reasons can you decide what to fix first.
