Which aspect of business does supply chain optimization specifically address?

Supply chain optimization specifically focuses on the cost and efficiency of the supply chain. This involves improving various aspects such as procurement, production processes, inventory management, logistics, and distribution. By optimizing these components, businesses aim to reduce operational costs, improve service levels, and enhance overall productivity. The goal is to streamline processes, reduce waste, and ensure that materials and products move through the supply chain as efficiently as possible. This not only contributes to better financial performance but also enhances competitiveness in the market.

Other options like staff management, market entry strategies, and marketing and branding, while important aspects of business, do not directly relate to the specific processes and metrics involved in supply chain optimization.
