Common Mistakes in Planner Coding: Capturing Unforeseen Events in Forecasting for Growing Brands

Manual planner coding helps capture unforeseen demand events, but common override mistakes can distort forecasts and inventory decisions. This blog explores key pitfalls and how to avoid them.

Planner Coding Is Prone to Error

Growing brands rely on planner coding to adjust forecasts in response to unforeseen demand events such as viral trends or supply disruptions.

However, manual override logic introduces risk when applied inconsistently.

Override inconsistency increases forecast distortion.

Mistake 1: Overestimating Uplift

Planners may apply uplift assumptions based on early demand signals without accounting for event duration.

Procurement decisions based on inflated forecasts lead to excess inventory.

Mistake 2: Ignoring Baseline Demand

Overrides applied to total demand rather than uplift components distort baseline consumption patterns.

Forecast reliability declines across event periods.

Mistake 3: SKU-Level Fragmentation

Overrides applied to individual SKUs fail to propagate across related items.

Inventory investment decisions become inconsistent.

Mistake 4: Channel-Level Misalignment

Planner coding may not reflect channel-specific demand variability.

Retail and DTC forecasts diverge.

Mistake 5: Lack of Governance

Override logic may accumulate without periodic review.

Forecast layers become misaligned across product hierarchies.

Ungoverned overrides propagate error.

Mistake 6: Procurement Timing Mismatch

Manual adjustments applied after demand spikes become visible often fail to align with supplier lead times.

Inventory arrives after peak consumption windows.

Improving Override Practices

For growing brands, avoiding common planner coding mistakes is essential to capturing unforeseen demand variability accurately.

Override practices must evolve into structured scenario evaluation mechanisms.
