Chronic Overstaffing from Inaccurate Sales Forecasts
Definition
Restaurants that build labor schedules on coarse or inaccurate daily sales forecasts routinely overstaff slow periods, pushing labor cost percentages above target and eroding already thin margins. Case work on a nationwide restaurant chain found that relying on recent historical patterns to break daily forecasts into intervals failed to capture real demand rhythms, resulting in inefficient staffing and higher payroll than necessary.
Key Findings
- Financial Impact: For a $3M/year restaurant targeting 30% labor, a 2–3 percentage point chronic labor overrun from overstaffing equals approximately $60,000–$90,000 per year in avoidable payroll; chain-level analytics projects report that improving interval-level forecasts by 16% can recapture a material share of this loss.
- Frequency: Daily
- Root Cause: Labor schedules are generated off high-level or naive daily sales forecasts that do not account for intra-day patterns, seasonality, holidays, weather, or local events, leading managers to “play it safe” and staff too many hours relative to true demand.
