Supply Chain Management
Definition
Supply chain management (SCM) is the coordination of all activities involved in sourcing, making, and delivering a product, from raw materials to the end customer. It aims to meet customer demand at the lowest total cost across the entire network.
In Practice
Supply chain management connects planning, procurement, manufacturing, logistics, and returns into one coordinated flow of materials, information, and money. Rather than optimizing each function in isolation, SCM asks how decisions in one area, such as a cheaper supplier with longer lead times, ripple through inventory, service, and cost everywhere else.
For a planner, SCM is the daily balancing act between service level and cost. Holding more stock protects sales but ties up working capital; running lean frees cash but raises stockout risk. Good SCM makes these trade-offs explicit and measurable through KPIs like fill rate, cash-to-cash cycle, and perfect order rate.
A consumer electronics brand, for example, must synchronize chip suppliers in Taiwan, assembly in Vietnam, ocean freight, and retail promotions in Europe. When any link slips, SCM disciplines such as S&OP and risk management determine whether customers ever notice.
