Explanation
According to the CTSC Exam Content Manual1, one of the characteristics of digital supply chain integration is that it "enables end-to-end visibility, collaboration, and optimization across the supply chain network". This means that digital supply chain integration aims to achieve efficiency and effectiveness across all the processes involved in planning, sourcing, transforming, and fulfilling products, rather than focusing on each process in isolation. Therefore, the best approach to support a digital supply chain for an apparel company is to emphasize integrated efficiency goals across all four processes, as this would enable the company to optimize its resources, reduce costs, improve quality, and meet customer expectations. Option A, C and D are examples of approaches that do not support digital supply chain integration, as they either focus on standalone goals for each process or prioritize revenue over efficiency.
