Library/Leak 08
Re-keying data between systems
The same information typed into two or more systems because they don't talk to each other.
How you know you have it
“Where do you type the same thing into two places? Where does data get re-entered?”
What kind of leak it is
Does it need your judgment?
A mechanical touch is an automation candidate: nothing is being decided, so a machine or a rule can hold it.
How to measure it
Annualized the same way everywhere: duration × frequency × people × 52.
Typical range — illustrative
An order of magnitude to prime your eye, not a statistic and not a claim about anyone's result. The only number that matters is the one you measure.
The move — Automate
