Round 98

Inventory Replenishment Policy

A mid-sized retailer is seeing stockouts on fast-moving items and excess inventory on slower items. Leadership wants a new replenishment policy for the next 12 months that improves service levels without tying up too much working capital. Constraints include limited warehouse space, uneven supplier lead times, seasonal demand spikes, and a planning team that can only review exceptions a few times per week. The decision should balance simplicity, responsiveness, and cost: overly strict rules may create firefighting, while overly flexible rules may be hard to operate consistently. The goal is to choose a policy that operations, finance, and purchasing can actually execute.
