Developments in Supply Chain Management
Six major movements can be observed in the evolution of
supply chain management studies creation, integration, and globalization (lavassani et al., 2008), specialization phases one and two, and SCM 2.0.
1. Creation Era
The term
supply chain management was first coined by an American industry consultant in the early 1980s however the concept of
supply chain in management, was of great importance log before in the early 20th century, especially by the creation of the assembly line, the chacteristics of this era of supply chain management include the need for large scale changes, reengineering, downsizing driven by cost reduction programs, and widespread attention to the Japanese practice of management.
2. Integration Era
This era of
supply chain management studies was highlighted with the development of electronic data interchange system in 1960s and developed through the 1990s by the introduction of enterprise resource planning systems. This era has continued to develop into the 21st century with the expansion of internet- based collaborative systems. This era SC evolution is characterized by both increasing value-added and cost reduction through integration.
3. Globalization Era
The third movement of
supply chain management development, globalization era, can be characterized by the attention towards global systems of supplier relation and the expansion of supply chain of organization can be traced back to several decades ago(e.g the oil industry), it was not until the late 1980s that considerable number of organization started to integrate sources into their core business. This era is characterized by the globalization with the goal of increasing competitive advantage, creating more value-added, and reducing costs through global sourcing.
Supply Chain Management Objectives
The objective of every
supply chain is to maximize the overall value generated. The value supply chain generates is the difference between what the final products is worth to the customer and the effect of
supply chain expends in filling the customer’s request the difference between the revenue generated from the customer and overall cost across the
supply chain.
For example a customer purchasing a computer from dell pays 2000 which represents the supply chain receives. Dell and other stages of the
supply chain incur cost to convey information and transport the item and transfer find of 2000 that the customer paid and sum of all the cost incurred.
Principles of Supply Chain Management
1. Introduction
Supply chain management has received a lot of attention and the terminology has been used (sometimes misused) by companies to describe the set of manufacturing and logistics processes the result in delivering a product to their customers.
The
supply chain encompasses all activities associated with the flow and transformation of goods from the raw materials stage, through to the end use as well as the associated information flows.
Supply chain management is the integration of these activities through improved supply chain relationship to achieve a competitive advantage.
2. Supply chains extend beyond immediate customer and supplier.
If your company produces many product which have different customers, suppliers and delivery methods, how do you deal with the complexity of your
supply chain? One approach used in the DAMA project was to pick a specific product, like a men’s nylon parka and trace the entire process step for the product from raw materials to its purchase by a consumer.
3. Supply chains are not constant.
Knowing that integration is difficult to accomplish, why would the companies want to spend the resources to synchronize their business processes? The study below shows why. There are big rewards for the successful partnerships.
4. Parallel data sharing is better than serial.
There is a somewhat obvious relationship between forecasting and lead-time that is frequently overlooked in
supply chain planning. If a company could produce near perfect forecasts, the lead-time to acquire the forecasted product would be unimportant. The lead time could be very long, although the dilemma is in reality, the further out the selling period; the less accurate that forecast is likely to be. The forecast accuracy would not be as important because the company could respond to whatever the current demand was in a very short time.
5. Forecasting and lead-time are symbiotic.
The globalization of the US soft goods industry has caused many companies to examine the total cost of procurement. In general, the further the product is made from the US market, the lower manufacturing cost and the higher the logistics cost. A source on the side of the world may have the cheapest manufacturing cost, but it will cost more to deliver. Keeping the correct balance will pay off at the company’s bottom line.
6. Manufacturing and logistics cost have inverse relationship.
The voluntary inter- industry commerce standards group has developed a set of business processes called collaborative planning, forecasting and replenishment which start with the premise that there should be one agreed upon view of demand.CPFR pilots between retailers and their suppliers have shown that sharing views of demand data demand data and collaborative on the differences result in increased sales, higher in-stock positions and lower inventory. This is accomplished because forecasting and planning processes increase in accuracy, which makes the supply chain responsive to the consumer.
