Start with a forecast
The roster is a bet on how busy you will be. Base that bet on data: look at sales or covers by day-of-week and day-part over recent comparable weeks, then adjust for events, weather and seasonality.
Translate demand into hours
- Estimate covers per day-part from the forecast.
- Apply a productivity standard (e.g. covers per server, tickets per line cook).
- Derive required labour hours per station per day-part.
- Build shifts that cover those hours with staggered starts.
Stagger, don't stack
Staggering start times to the demand curve — rather than everyone starting together — is where most labour savings hide.
