Supply chain capabilities are guided by the decisions you make regarding the five supply chain drivers. Each of these drivers can be developed and managed to emphasize responsiveness or efficiency depending on changing business requirements. As you investigate how a supply chain works, you learn about the demands it faces and the capabilities it needs to be successful. Adjust the supply chain drivers as needed to get those capabilities.
A different path to better inventory performance. The supply chain executive was puzzled. 'If I were to combine the promised inventory benefits of all recent performance-improvement projects,' she said, 'my company today would be achieving 100 percent customer service levels while maintaining negative inventory. Supply Chain Performance crosses company boundaries since it includes basic materials, components, subassemblies and finished products, and distribution through various channels to the end customer. It also crosses traditional functional organization lines such as procurement, manufacturing, distribution, marketing & sales, and research. Provide products, services, and information that add value for customers and other stakeholders (Lambert et al., 1998). Supply chain management makes use of a growing body of tools, techniques, and skills for coordinating and optimizing key processes, functions, and relationships, both within the OEM and among its suppliers and customers, to enable and capture opportunities for synergy.
The five drivers provide a useful framework for thinking about supply chain capabilities. Decisions made about how each driver operates will determine the blend of responsiveness and efficiency a supply chain is capable of achieving. The five drivers are illustrated in the diagram below:
1. PRODUCTION – This driver can be made very responsive by building factories that have a lot of excess capacity and use flexible manufacturing techniques to produce a wide range of items. To be even more responsive, a company could do their production in many smaller plants that are close to major groups of customers so delivery times would be shorter. If efficiency is desirable, then a company can build factories with very little excess capacity and have those factories optimized for producing a limited range of items. Further efficiency can also be gained by centralizing production in large central plants to get better economies of scale, even though delivery times might be longer.
[Simulate decisions about production in SCM Globe by defining different products and facilities in the supply chain, and select locations for the facilities that make those products.]
2. INVENTORY – Responsiveness can be had by stocking high levels of inventory for a wide range of products. Additional responsiveness can be gained by stocking products at many locations so as to have the inventory close to customers and available to them immediately. Efficiency in inventory management would call for reducing inventory levels of all items and especially of items that do not sell as frequently. Also, economies of scale and cost savings can be gotten by stocking inventory in only a few central locations such as regional distribution centers (DCs).
[Decisions about inventory are simulated by setting production rates and delivery schedules for products, and by defining on-hand amounts for different products at facilities throughout the supply chain.]
3. LOCATION – A location decision that emphasizes responsiveness would be one where a company establishes many locations that are close to its customer base. For example, fast-food chains use location to be very responsive to their customers by opening up lots of stores in high volume markets. Efficiency can be achieved by operating from only a few locations and centralizing activities in common locations. An example of this is the way e-commerce retailers serve large geographical markets from only a few central locations that perform a wide range of activities.
[Simulate this decision by placing your facilities (factories, warehouses, stores) in selected locations, and then define the storage capacities and operating expenses for those facilities. The screenshot below shows an example of this.]

4. TRANSPORTATION – Responsiveness can be achieved by a transportation mode that is fast and flexible such as trucks and airplanes. Many companies that sell products through catalogs or on the Internet are able to provide high levels of responsiveness by using transportation to deliver their products often within 48 hours or less. FedEx and UPS are two companies that can provide very responsive transportation services. And now Amazon is expanding and operating its own transportation services in high volume markets to be more responsive to customer desires. Efficiency can be emphasized by transporting products in larger batches and doing it less often. The use of transportation modes such as ship, railroad, and pipelines can be very efficient. Transportation can also be made more efficient if it is originated out of a central hub facility or distribution center (DC) instead of from many separate branch locations.
[Simulate transportation decisions in SCM Globe by the modes of transportation (truck, railroad, ship, airplane) you use to move products between facilities, and by the delivery routes and frequencies you define.]
5. INFORMATION – The power of this driver grows stronger every year as the technology for collecting and sharing information becomes more wide spread, easier to use, and less expensive. Information, much like money, is a very useful commodity because it can be applied directly to enhance the performance of the other four supply chain drivers. High levels of responsiveness can be achieved when companies collect and share accurate and timely data generated by the operations of the other four drivers. An example of this is the supply chains that serve the electronics market; they are some of the most responsive in the world. Companies in these supply chains, the manufacturers, distributors, and the big retailers all collect and share data about customer demand, production schedules, and inventory levels. This enables companies in these supply chains to respond quickly to situations and new market demands in the high-change and unpredictable world of electronic devices (smartphones, sensors, home entertainment and video game equipment, etc.).
What Are The Drivers Of Supply Chain
[SCM Globe simulations generate daily performance data on operating costs and inventory levels for all the facilities in the supply chain. As you run a simulation you can see what is happening from end to end across your supply chain. At present most companies don’t have access to this kind of data about the overall status of the supply chains they participate in — but that will change as all markets take on the high-change and unpredictable nature seen in the electronics market.]
The table below summarizes what can be done to guide the five supply chain drivers toward responsiveness or efficiency. Companies and supply chains continually adjust their mix of responsiveness and efficiency as situations change.
Over the long run, the cost of one driver — Information — continues to drop while the cost of the other four drivers continues to rise. Companies that make best use of information to increase their internal efficiency, and increase their responsiveness to external supply chain partners will gain the most customers and be the most profitable.
WHEN TO BE EFFICIENT AND WHEN TO BE RESPONSIVE
Efficiency is good — In the 20th century, efficiency drove economic growth. The push for efficiency increased productivity and lowered the prices of products from automobiles to home appliances thus making them available to a wide segment of the population. Yet efficiency requires two things that are becoming much harder to find. The first thing is predictability. To efficiently plan and manage production and distribution of products you need to know what the demand will be for those products, and you need to know what the cost of raw materials will be and what the selling prices will be for the products. Then you can optimize your operations to produce the right amounts at the right prices and maximize profits.
Efficiency also requires one more thing — stability. You need to know that demand and prices will remain relatively stable for some number of years (5 or 10 years or more). Because then you can build factories and stores and transportation infrastructure to enable your efficient operating model. Efficiency is best when producing relatively simple commodity products and services that sell in more predictable and stable markets.
Responsiveness is better — In the 21st century, responsiveness drives the economy. Responsiveness is what drives continuous innovation in products and technology and continuous change in the ways we organize businesses and serve customers. The big companies of the 20th century were efficient manufacturing companies (Ford, GM, US Steel, Kodak, Whirlpool etc.), but the big companies of the 21st century are responsive service and technology companies (Alibaba, Amazon, Apple, Facebook, Google, Starbucks, Tencent, etc.). All these 21st century companies certainly need to be efficient, but their success is based mostly on their ability to sense and respond quickly to changing markets and evolving customer desires. Lowest price is not always the deciding factor in purchasing decisions. People want products and services that respond quickly and meet their changing needs and desires.
Apple and Starbucks do not sell the lowest priced laptops or cups of coffee, nor does Porsche or Tesla make the lowest priced automobiles, but as long as people value the quality and innovation offered by those companies and others like them, they will pay more for their products. Home delivery of everything from clothes to groceries costs a bit more, but people value and pay for the responsiveness and convenience of those services. Responsiveness is best when providing complex or unique products and services that sell in continuously changing markets driven by evolving technology and new customer needs and desires.
THE RIGHT MIX OF EFFICIENCY AND RESPONSIVENESS
Even within supply chains that emphasize responsiveness, there are segments of those supply chains that should focus on efficiency. Efficiency is critical wherever there are high volumes of predictable products moving between facilities. For example, segments of supply chains that connect factories with warehouses or distribution centers should be as efficient as possible. They should use the most efficient transportation modes and delivery schedules, and those facilities should automate their operations as much as possible.
However, segments of supply chains that connect distribution centers to end use customers usually focus on responsiveness. These segments are known as “last mile” deliveries. They use transportation modes and delivery schedules that emphasize responsiveness because customers have come to expect fast delivery of products. In every supply chain some operations will need to focus on efficiency, and others on responsiveness. That mix continues to shift over time as customer preferences, market conditions, and technologies change.
New technologies such as robots, drones, artificial intelligence and 3D printing are making big impacts on how supply chains operate. And yet after all is said and done, these new technologies can be employed to do one of two things: increase efficiency; or increase responsiveness (or some blend of the two). See our blog post “Five New Supply Chain Technologies and How to Use Them” for ideas about how new technologies can be used to improve efficiency and responsiveness, and create supply chains that become competitive advantages.
One company making good use of information and technology to manage their supply chain is Zara Clothing Company. Zara’s supply chain is a big competitive advantage (screenshot below shows a portion of Zara’s supply chain in Spain). It sells unique clothing products in a constantly changing market shaped by popular fashion and new customer desires. See our case study about how Zara’s supply chain enables it’s unique business model – “Zara Clothing Company Supply Chain“.

In retailing business, usually five chain drivers are in practice.
These are as follows:
1. Procurement:
This issue is related to the following retailing aspects:
ADVERTISEMENTS:
(i) What to buy?
(ii) When to buy?
(iii) How to buy?
(iv) Where to buy? And
(v) From whom to buy?
2. Merchandise Management:
The issues may be related to how much to display and how much to store as reserve stock and where to store the merchandise (in the retail store itself or in the warehouse).
3. Store location:
A number of issues regarding location such as where to set up a store, where to locate a warehouse facility, how many stories to construct, may have significant bearing on the dynamics of the supply chain, and in turn may affect the overall budget of the retail store.
4. Transportation:
What Are The Drivers Of Supply Chain Performance
Under transportation, a retailer is concerned with the following aspects:
Explain Various Drivers Of Supply Chain Performance Powerpoint
ADVERTISEMENTS:
How to move a product from one store to another. For example, in case of centralized retailing, delivery takes from common warehouse to different stores located in different areas at varied distance. Here, a retailer is always worried about the mode of transportation because on one hand, he is concerned with economies of scale and desired level of customer satisfaction on the other hand.
5. Information:
Information is an integrating force that has critical implications for the whole supply chain. For a retailer, information (Data) acts as basis for making various decisions in the supply chain. If information is not understood properly, it can disrupt the whole supply chain and consequences may be fatal for retailer’s fate.
