Common Mistakes in Moving Seasonality vs Fixed Seasonality in Demand Forecasting for Growing Brands
Learn the most common mistakes demand planners make when seasonal demand begins shifting across promotional cycles.
Why Seasonal Forecasting Errors Compound as Brands Grow
Seasonality-related forecasting errors often remain unnoticed during early growth phases when SKU counts are limited and channel complexity is low. However, as brands expand across marketplaces, retail partnerships, and international markets, seasonal demand patterns begin to shift dynamically based on business activity.
Demand planners frequently assume that seasonal demand follows stable year-over-year patterns, resulting in inventory procurement decisions based on outdated timing assumptions.
Assuming Promotion Timing Remains Constant
Promotions often shift across fiscal quarters due to campaign strategy changes, supplier constraints, or marketing experimentation.
Ignoring Marketplace-Driven Demand
Marketplace demand surges driven by algorithmic ranking changes rarely align with traditional seasonal cycles.
Treating All SKUs Equally
Different SKUs exhibit distinct demand behaviors such as promotion-driven or lifecycle-driven demand.
Manual Override Dependency
Manual forecast overrides rarely scale effectively in environments where seasonal demand peaks move continuously.
Behavior-Aware Planning Prevents Seasonal Forecasting Errors
