What causes over prep and under prep, and how do you stop both?
Attack the two most expensive prep mistakes at their shared root.
Both come from prepping without a target. Guessing high wastes food, labor, and cash at close, while guessing low weeds the line with a mid-rush eighty-six that loses sales. The shared cure is a real par to prep against, tuned with prep history so both errors shrink over a few weeks.
Two errors, one cause
Over prep and under prep look opposite, but both come from prepping without a target. Guessing high wastes food, guessing low weeds the line. Related: How can prep history help you tighten par levels over each season?
The cure for both is the same, which is a par to prep against instead of a feeling.

The cost of over prep
Every over-prepped item is food, labor, and cash you throw away at close. It hides in the trash where no one adds it up. Related: How should shelf life cap how much of each item a kitchen preps at once?
A par tuned to real usage stops the reflex to make extra just in case, which is where most waste starts.
The cost of under prep
Under prep is quieter but just as costly, because a mid-rush eighty-six loses sales and rushes cooks into sloppy work.
Higher pars on your fast movers, especially for weekends, keep the line from running dry when it matters most.
Let the data settle it
Prep history removes the argument, showing exactly which items ran short and which got tossed. Adjust the pars accordingly. Related: Why should prep par levels change by day of the week for a kitchen?
A few weeks of honest tracking turns prep from a daily debate into a routine that mostly runs itself. Related: How do you build a daily prep list from par levels the right way?

Frequently asked questions
Why is over prep so easy to miss?
Over-prepped food hides in the trash at close, where no one adds it up. A par tuned to real usage stops the reflex to make extra just in case, which is where most of that waste starts.
How do you avoid running out of a fast mover?
Set higher pars on your fast movers, especially for weekends when they get stressed hardest. That keeps the line from running dry mid-rush, which loses sales and forces cooks into rushed, sloppy work.
