Forecasting Fundamentals
Demand Planning - The process of predicting future customer demand to optimize inventory and production.
Statistical Forecast - Baseline demand prediction using historical data and mathematical models.
Consensus Forecast - Final demand plan combining statistical models with business intelligence and market insights.
Forecast Accuracy - Measure of how close predictions are to actual results, typically expressed as MAPE or bias.
MAPE - Mean Absolute Percentage Error. Key metric measuring forecast accuracy.
Forecast Bias - Tendency to consistently over-forecast (positive bias) or under-forecast (negative bias).
Forecast Horizon - Time period being forecasted (short-term, medium-term, long-term).
Rolling Forecast - Continuously updated forecast that extends the planning horizon as time progresses.
Baseline Volume - Expected sales without promotional activity or unusual events.
Incremental Volume - Additional sales generated by promotions, new distribution, or marketing activities.
Forecasting Models and Methods
Time Series Analysis - Forecasting method using historical patterns, trends, and seasonality.
Causal Models - Forecasting using relationships between demand and external factors (price, weather, promotions).
Holt-Winters - Exponential smoothing method that captures trend and seasonality.
ARIMA - AutoRegressive Integrated Moving Average model for time series forecasting.
Machine Learning Models - AI-based forecasting using algorithms like random forest or neural networks.
Ensemble Forecasting - Combining multiple forecasting methods to improve accuracy.
Judgmental Override - Manual adjustment to statistical forecasts based on business knowledge.
Seasonality and Patterns
Seasonality Index - Measure of how much demand varies by season compared to average.
Peak Season - Period of highest demand for a product category.
Seasonality Profile - Pattern showing how sales vary throughout the year.
Base-Seasonal-Promotional Decomposition - Breaking down demand into underlying components.
Holiday Lift - Sales increase during holiday periods.
Weather Impact - How temperature, precipitation, etc. affect product demand.
Trade and Promotional Forecasting
Trade Promotion - Temporary incentives offered to retailers to drive sales.
Promotional Lift - Incremental sales generated by a specific promotion.
Lift Curve - Graph showing sales impact over the duration of a promotion.
Promo Types - Different promotional mechanics (TPR, BOGO, coupon, display, etc.).
Feature Support - Advertisement in retailer's circular or flyer.
Display Support - Special in-store placement during promotion.
Price Elasticity - Sensitivity of demand to price changes, measured as % demand change / % price change.
Cross-Price Elasticity - How price changes of one product affect demand for another.
Trade Planning and Execution
Trade Calendar - Schedule of all planned promotional activities.
Promo Planning - Process of determining optimal promotion timing, mechanics, and investment.
Event Planning - Coordinating promotional activities across multiple retailers.
Trade Rate - Percentage of sales sold on promotion vs. at regular price.
Promoted Price Point - The discounted retail price during promotion.
Promotion ROI - Return on investment for promotional spending.
Incrementality - True additional sales generated by promotion (excluding baseline and cannibalization).
Forward Buy - Retailers purchasing extra inventory to take advantage of trade deals.
Trade Loading - Inflated shipments due to promotional timing that may not reflect true demand.
Advanced Forecasting Concepts
New Product Forecasting - Predicting demand for products without sales history.
Analog Method - Using similar existing products to forecast new product performance.
Market Research Integration - Incorporating consumer research data into demand forecasts.
External Data Integration - Using third-party data (weather, economic indicators) in forecasting.
Demand Sensing - Short-term forecasting using real-time signals like POS data.
Collaborative Planning - Joint forecasting process between manufacturer and retailer.
CPFR - Collaborative Planning, Forecasting and Replenishment between trading partners.
Performance Measurement
Forecast KPIs - Key performance indicators measuring forecasting effectiveness.
Tracking Signal - Measure of forecast bias over time.
Forecast Value Added (FVA) - Improvement in accuracy from forecast adjustments.
Demand Plan Attainment - How well actual results match the demand plan.
Service Level - Percentage of demand met from available inventory.
Stockout Cost - Financial impact of not having product available when demanded.
Excess Inventory Cost - Cost of carrying too much inventory due to over-forecasting.
