This document defines and discusses quick response (QR). QR aims to provide customers with a diverse range of products and services in exact quantities and at the right time, place, and price based on real-time demand. It was developed in the late 1980s based on the Japanese concept of time-based competition. QR focuses on reducing lead times throughout the supply chain to improve quality, reduce costs, and eliminate waste. It requires responsiveness, reliability, resilience, and relationships between supply chain members. When implemented successfully, QR benefits suppliers and retailers through reduced inventory, improved cash flow, higher sales and profits, and enhanced customer satisfaction.
