Common Mistakes in Moving Seasonality vs Fixed Seasonality in Demand Forecasting for $10M–$100M Companies
Avoid the most common pitfalls mid-market teams encounter when adapting seasonal forecasting.
Transitioning to Moving Seasonality Requires More Than Overrides
As companies grow from $10M to $100M in revenue, demand patterns increasingly reflect promotional cadence, lifecycle shifts, and channel diversification rather than fixed calendar repetition.
Mid-market planning teams attempting to transition from fixed to moving seasonality often encounter implementation challenges that undermine forecast reliability.
1. Treating Promotional Demand as Seasonal Demand
Promotional uplift may be misclassified as inherent seasonal demand.
This distorts baseline forecasts and leads to over-procurement during non-promotional periods.
2. Applying Uniform Seasonality Across SKUs
Demand behavior varies across product categories and lifecycle stages.
Uniform seasonal indices may obscure SKU-specific demand drivers.
3. Ignoring Lifecycle Transitions
New product launches or transitioning SKUs may exhibit demand patterns that differ from mature products.
Blending lifecycle-driven demand with seasonal demand may introduce forecast bias.
4. Relying on Manual Overrides
Manual adjustments to align seasonal demand with promotional timing are labor-intensive.
Override dependency increases planning workload and error propagation.
5. Failing to Update Procurement Timing
Even when forecasts reflect moving seasonality, procurement schedules may remain tied to historical lead times.
Inventory arrival may therefore precede actual demand peaks.
6. Limited Scenario Evaluation
Promotional timing scenarios may not be evaluated systematically.
Unanticipated demand timing shifts introduce inventory risk.
7. Underestimating MOQ Constraints
Minimum order quantities may amplify procurement misalignment.
Overbuying increases holding costs.
Avoiding Implementation Pitfalls
Segmenting demand drivers and aligning procurement schedules with dynamically modeled demand peaks reduces inventory risk.
