Retail replenishment beyond static min/max rules
Why classic min/max fails seasonal categories—and how to layer demand signals without a science project.
By Morgan Ellis
Static thresholds are a reasonable first system. They fail when seasonality, promotions, or supplier lead times shift underneath you.
Upgrade with simple layers: promotional calendars feeding temporary thresholds, vendor-managed exceptions for hero SKUs, and weekly reviews that look at weeks-of-cover by class.
Keep the math explainable to store managers—if they cannot trust the recommendation, they will override it and you are back to intuition.
