Mass Customization is a strategic approach in the retail industry that involves providing products customized or tailored to individual customer preferences on a larger scale. Unlike traditional mass production, which produces identical items in large quantities, mass customization combines elements of personalization with efficient production processes. Retailers leverage technologies and flexible manufacturing systems to offer a variety of customizable options to customers without sacrificing efficiency. This approach allows customers to have unique products while benefiting from the economies of scale associated with mass production. Mass customization is particularly relevant in industries such as apparel, footwear, and technology, where consumers increasingly seek personalized and unique experiences.
