What is Supply Chain Management?

Supply chain management (SCM) refers to the planning, execution, and oversight of the flow of goods, services, information, and finances from the point of origin to the final consumer. The goal of SCM is to optimize these processes to meet customer demand while minimizing costs and maximizing efficiency.

In simpler terms, SCM covers everything involved in getting a product from its raw material stage to the hands of the customer. This process includes sourcing raw materials, production, warehousing, transportation, and even customer service. SCM ensures that each step of the process is as efficient as possible, reducing waste, lowering costs, and delivering products quickly.

SCM can be broken down into three main elements:

1. Supply: Involves sourcing and procuring raw materials or components.
2. Manufacture: Concerns the processes and operations involved in producing goods.
3. Distribution: Deals with the delivery of finished products to customers or retailers.

How Supply Chain Management Works

SCM is a complex process that involves several stages and activities, including planning, sourcing, manufacturing, logistics, and return. The smooth functioning of the supply chain relies on the integration and coordination of each step, often supported by advanced technology and real-time data.

1. Planning

Good planning is required for almost every process. This is the initial step of every process. Good planning can give us a lot of clarity and it can eliminate lots of problems and confusion from the beginning. Taking about supply chain management in specific planning usually involves how to manage all resources and other steps involved in processing goods or services and fulfilling the customer demand. Planning is also the base of other steps involved in the process of supply chain management. Planning involves how to source the raw materials, how to manufacture the goods, how to manage the transportation of the goods and raw materials, and finally how to deal with the return of defective goods that have been delivered to the customer.

2. Sourcing  

The next step involved in the process of supply chain management is sourcing. Sourcing involves selecting the suppliers to provide us with raw materials or services which are involved in the production of goods and services. Then it involves monitoring the services done by the supplier and maintaining a good relationship with the supplier. The key process of sourcing includes ordering the raw material and goods, receiving them, managing the inventories, and managing the payments to them.

3. Manufacturing

The next step after sourcing the goods is manufacturing. Manufacturing involves accepting and processing the raw materials, manufacturing the goods or service, testing for any faults or defects, and finally delivering it to the customer. Supply chain managers should monitor every step that is involved in the function of manufacturing so that there won’t be any problems arising.

4. Logistics 

Logistics or delivery of the product is important since the producers want the goods to reach their customers without any hassles or delay. Supply Chain managers should monitor the orders made by the customers, schedule the order, and make sure that it reaches the order within the time and without any problems, making the invoice of the order and make sure that they receive the payments correctly.

5. Returns 

Every production of goods or services cannot be 100% perfect. There might be cases of defective or wrong products delivered to the customer. It can occur due to the faults that happen during the production of the good or while the order was being processed. Human or machine errors are something that we cannot eradicate. There might be also instances where the customer didn’t like the product or doesn’t need the product or service anymore. It may not be the fault of the producer. So supply chain managers should create a system that can handle the return of such goods back to the producer.

SCM can be further supported by various technologies like ERP systems, inventory management software, transportation management systems (TMS), and warehouse management systems (WMS) to optimize and integrate each stage of the supply chain.

Phases of Supply Chain Management

Supply chain management operates in various phases, each critical to ensuring efficiency and effectiveness.

1. Strategic Phase: In this phase, long-term decisions are made. These include selecting suppliers, designing the supply chain, and determining the location of factories, warehouses, and distribution centers. Decisions made at this stage have a long-term impact on cost, efficiency, and customer satisfaction.
2. Tactical Phase: This phase involves shorter-term decisions that can be adjusted based on market conditions. Tactical decisions include inventory levels, transportation routes, and production schedules. The tactical phase allows companies to respond to changes in demand, supplier availability, or shipping delays.
3. Operational Phase: Day-to-day activities such as order processing, delivery scheduling, and inventory tracking are part of the operational phase. This phase focuses on execution and ensuring that the supply chain runs smoothly in real-time.
