This research explored the evolution of digital technologies and the analog-to-digital shift in supply chain processes with a specific emphasis on ink jet printing and digital product supply. The technology for ink jet printing was researched along with technology management principles and supply chain strategies such as quick response, agile manufacturing, and mass customization. The research into digital technologies led to the distinction between digital processes and digital products. The objective was to model a digital product supply chain and map the relationship of digital products to a physical process supply chain for the textile and apparel industry. Models were developed for three product categories: traditional woven garments, digitally printed garments, and digitally knitted garments. For each model a process capability table was constructed that listed the major supply chain activities from garment design to shipping manufactured product. Each activity was assumed to use state-of-the-art technology and was identified as either digital or physical. Process limitations were noted for each activity and the state of the product was tracked from its digital beginning until it was converted to a physical entity. The results verified that process limitations are minimized when digital processes are implemented and supply chains are more efficient when products are digital. The models were verified using industry experts in manufacturing, technology development, and research, The digital supply chain model is strategically important because it shifts supply chain thinking from a physical process orientation to a digital product orientation. Future strategy will incorporate digital products that are digitally designed, digitally marketed, digitally manufactured, and digitally distributed.
