In many ways,the responsive business model is similar to the traditional build-to-order manufacturing .the primary differences between modern responsive operations and traditional build-to-order are the time to execute and the degree of potential customization.while response-based examples are observable in many different industries,a hight degree of attention has focused on the operational model developed by Dell Corporation.In 2004 Dell perfected a responsive distribution model wherein computers sold in the United States were built to order in China and delivered to United States consumers within a five-day order-to-delivery cycle.
