The Expert Guide to Retail Assortment Planning

Strengthen your assortment planning capabilities for better business results.

Retail assortment planning is a strategic process that aligns product offerings with customer preferences, demand forecasts, store/channel formats, and business objectives. Every retailer knows that assortment planning can make or break results. Yet many leaders still struggle with:

  • Misaligned assortments that don’t reflect customer demand
  • Fragmented processes across financial, item, and space planning
  • Technology that falls short of expectations
  • Merchandising and planning teams working in silos

These challenges are magnified during critical seasons like back-to-school and holiday, when your assortments define your brand in the eyes of your customers.

Effective assortment planning blends the art of merchant intuition with the science of advanced analytics and well-integrated systems. Further, leading retailers treat assortment planning as a strategic capability, fully integrated with merchandise financial planning, product development, space planning, allocation, and replenishment. As retail evolves with omnichannel expectations, inventory volatility, and rising consumer expectations, having a flexible, data-driven, and collaborative assortment planning process is more important than ever.
