The most suitable forecasting method for short-term forecasts in foodservice is

• A. Moving average
• B. Delphi method
• C. Time-series
• D. Causal modeling

Answer: (C)

Time-series forecasting focuses on how demand has varied over recent time and uses that history to predict near-term needs. In foodservice, short-term demand is shaped by recent patterns—weekday versus weekend demand, holidays, and promotions—and a time-series approach directly captures these patterns from past data, updating as new data comes in. It can model recurring seasonality and any short-term trends, and can give more weight to recent observations to stay responsive to changing conditions, which is exactly what you need for daily or weekly forecasts in a restaurant or cafeteria setting. A simpler method like the moving average also uses past data but treats all periods in the window equally and often misses evolving trends or seasonal effects, making it less flexible for the irregularities seen in foodservice demand. The Delphi method relies on expert opinions and is better suited for longer-range forecasts, while causal modeling depends on external drivers (like price or weather) whose relationships with demand can be unstable in the short term and harder to quantify reliably. So, time-series is the most appropriate choice for short-term forecasting in foodservice.
