Current State vs Future State Comparison
Current State
(Traditional)1. Demand planner exports last 24 months sales data into Excel spreadsheet for each SKU category. 2. Manually calculates simple moving averages and applies seasonal factors from previous year: 'Summer months +15%, winter months -10%, December +200% for toys category'. 3. Adjusts forecasts based on gut feeling and knowledge of upcoming promotions or market trends. 4. Forecast accuracy 60-70% due to limited data analysis and inability to detect complex patterns. 5. Stockouts occur 15-20% of time during demand spikes (underforecasted), overstock 25-30% during slow periods (overforecasted).

Pain Points
- ⚠ Data Quality Issues - Inconsistent, incomplete, or inaccurate data leads to poor forecasts.
- ⚠ Manual Processes - Heavy reliance on Excel and email slows down the process and increases error risk.
- ⚠ Lack of Integration - Forecasting tools often not integrated with ERP/MRP, causing delays and misalignment.
- ⚠ Model Limitations - Traditional statistical models struggle with sudden demand shifts or new product introductions.
- ⚠ Forecast Accuracy - Typical MAPE for statistical forecasts ranges from 20% to 50%.
- ⚠ Time-Consuming Review Cycles - Manual review and adjustment of forecasts can take days or weeks.
- ⚠ Limited Scenario Planning - Traditional models are not well-suited for 'what-if' analysis or rapid response to disruptions.
Future State
(Agentic)1. Statistical Forecasting Agent ingests 5+ years historical sales data across all SKUs with seasonality, promotions, weather, economic indicators. 2. Agent applies exponential smoothing (Holt-Winters) and ARIMA models automatically: detects double-seasonality (weekly + yearly), trend changes, promotion effects. 3. Seasonal Decomposition Agent identifies multi-layer patterns: 'Ice cream sales show weekly peak Fri-Sat (+40%), summer season (+300% Jun-Aug), heat wave correlation (+25% when temp >85°F)'. 4. Agent generates SKU-level forecasts 13 weeks ahead: 'Vanilla ice cream SKU#12345 forecast 5,200 units week of July 4 (vs 2,000 normal) due to Independence Day + summer + heatwave predicted'. 5. Forecast accuracy improves to 75-85% through statistical rigor and multi-variable analysis. 6. Stockouts reduced 40% (15-20% → 9-12%) and overstock reduced 30% (25-30% → 17-21%) through better predictions.
Characteristics
- • 5+ years historical sales data (transactions by SKU, date, location)
- • Promotional calendar with discount levels and advertising spend
- • Seasonal patterns (weekly, monthly, yearly, holiday calendars)
- • External data (weather forecasts, economic indicators, competitor activity)
- • Inventory Management levels and stockout history
- • Price changes and elasticity data
Benefits
- ✓ 75-85% forecast accuracy vs 60-70% manual spreadsheet analysis
- ✓ 40% stockout reduction (15-20% → 9-12%) through better demand prediction
- ✓ 30% overstock reduction (25-30% → 17-21%) minimizing waste
- ✓ SKU-level forecasting vs category-level (10,000+ SKUs analyzed)
- ✓ Multi-seasonality detection (weekly, monthly, yearly patterns combined)
- ✓ 13-week rolling forecasts updated automatically vs manual monthly
