• {{time_period}}: The period for comparison (e.g., past month, quarter, year).

Instructions

2. Compare actual sales with predicted values, calculating discrepancies.
3. Identify significant deviations and patterns in the discrepancies.
4. Recommend adjustments to the forecasting model or process.
