Strategic Assortment Targets
Assortment planning begins with clear financial and strategic objectives. Revenue targets, margin goals, channel strategies, and brand positioning guidelines define the framework within which assortment decisions are made.
Consumer Demand and Performance Analysis
Historical sales data, size performance, price sensitivity, and regional buying behavior are analyzed to understand what drives demand at cluster and store level. This ensures assortments reflect actual customer preferences.
Define Category Roles and Space Allocation
Each category is assigned a role (core, seasonal, fashion, traffic driver) and allocated space accordingly. Floor space, digital shelf space, and investment are distributed to support strategic priorities.
Assortment Structure Definition
The assortment is structured by defining breadth (number of styles), depth (units per style), price architecture, and attribute mix (color, fit, material, trend). This step ensures commercial balance and brand coherence.
Localize by Cluster and Channel
Assortments are tailored by geography, store cluster, and channel to reflect different demand profiles. Localization increases relevance while maintaining overall brand consistency.
SKU and Size Curve Planning
Planners evaluate the expected revenue, margin, and inventory implications of the assortment structure through scenario simulations before execution.
Monitor and Refine In-Season
Performance is continuously tracked to adjust depth, replenish best sellers, rebalance underperformers, and refine future assortments.
