Learning Objective

3.  Examine the relationship between global value chain and global supply chain management.

From the Value Chain to Best Value Supply Chain

“Time is money!” warns a famous saying. This simple yet profound statement suggests that organizations that quickly complete their work will enjoy greater profits, while slower-moving firms will suffer. The belief that time is money has encouraged the modern emphasis on supply chain management. A supply chain is a system of people, activities, information, and resources involved in creating a product and moving it to the customer.

Supply chain is a broader concept than value chain; the latter refers to activities within one firm, while the former captures the entire process of creating and distributing a product, often across several firms. 

Supply-chain management encompasses the planning and management of all activities involved in sourcing and procurement, conversion, and logistics. Importantly, it also includes coordination and collaboration with channel partners, which can be suppliers, intermediaries, third-party service providers, and customers. In essence, supply-chain management integrates supply-and-demand management within and across companies.

Activities in the supply chain include:

  • demand management (e.g., forecasting, pricing, and customer segmentation),
  • procurement (e.g., purchasing, supplier selection, and supplier-base rationalization),
  • inventory management (e.g., raw materials and finished goods),
  • warehousing and material handling,
  • production planning and control (e.g., aggregate planning, workforce scheduling, and factory operations),
  • packaging (i.e., industrial and consumer),
  • transportation management,
  • order management,
  • distribution network design (e.g., facility location and distribution strategy), and
  • product-return management.


Spotlight on International Strategy and Entrepreneurship: Entrepreneurial Innovation at P&G

In 2002, Procter & Gamble (P&G) created a test factory, called the Garage, in Vietnam to experiment with low-cost diaper manufacturing for emerging markets. This factory was different from P&G’s US-based factories because it didn’t use high-tech, automation-intensive manufacturing processes. Rather, P&G wanted a low-cost, low-tech solution. The factory helped P&G devise a new, low-cost approach to manufacturing in emerging-market countries. The strategy required finding local suppliers, some of whom wouldn’t have been acceptable for other P&G products but were suitable for this one. P&G formed a network of 150 low-cost machine builders who could supply manufacturing equipment to P&G’s Vietnam factory. This manufacturing equipment was appropriate for emerging-market sites and emerging-market prices. The equipment was not on par to P&G’s US-based manufacturing equipment, but P&G could use it in other countries and in other product lines. For example, P&G took the lessons and machine-building know-how it had learned from making low-cost diapers in Asia and applied it to reducing the costs of making feminine pads in Mexico. In transferring this know-how from one country to the next, P&G reduced the costs of its feminine pads in Mexico by 20 percent.

P&G has gone a step further and brought its results back home to the United States in two ways. First, thanks to the North American Free Trade Agreement (NAFTA), P&G can import its low-cost feminine pads from Mexico back into the United States. Second, P&G now sees an opportunity to give a second life to obsolete plants in the United States. The experience P&G has gained in emerging markets has taught the company that not every product in every market needs the latest and greatest approaches to manufacturing in order to be successful. P&G’s experience with its Vietnamese factory has given it a scalable approach, which has enabled P&G to make diapers and other similar personal-care products in many different emerging-market countries using widely available, low-cost manufacturing equipment.

Competition in the 21st century requires an approach that considers the supply chain concept in tandem with the value-creation process within a firm: best value supply chains. These chains do not fixate on speed or on any other single metric. Instead, relative to their peers, best value supply chains focus on the total value added to the customer.

Creating best value supply chains requires four components. The first is strategic supply chain management — the use of supply chains as a means to create competitive advantages and enhance firm’s performance. Such an approach contradicts the popular wisdom centered on the need to maximize speed. Instead, there is recognition that the fastest chain may not satisfy customers’ needs. Best value supply chains strive to excel along four measures:

  • Speed (or “cycle time”) is the time duration from initiation to completion of the production and distribution process.
  • Quality refers to the relative reliability of supply chain activities.
  • Supply chains’ efforts at managing  cost involve enhancing value by either reducing expenses or increasing customer benefits for the same cost level.
  • Flexibility refers to a supply chain’s responsiveness to changes in customers’ needs. Through balancing these four metrics, best value supply chains attempt to provide the highest level of total value added.

Did You Know?

The value of Strategic supply chain management is reflected in how firms such as Walmart have used their supply chains as competitive weapons to gain advantages over peers. Walmart excels in terms of speed and cost by locating all domestic stores within one day’s drive of a warehouse while owning a trucking fleet. This creates distribution speed and economies of scale that competitors simply cannot match. When Kmart’s executives decided in the late 1990s to compete head-to-head with Walmart on price, Walmart’s sophisticated logistics system enabled it to easily withstand the price war. Unable to match its rival’s speed and costs, Kmart soon plunged into bankruptcy. Walmart’s supply chains also possess strong quality and flexibility. When Hurricane Katrina devastated the Gulf Coast in 2005, Walmart used not only its warehouses and trucks but also its satellite technology, radio frequency identification (RFID), and global positioning systems to quickly divert assets to affected areas. The result was that Walmart emerged as the first responder in many towns and provided essentials such as drinking water faster than local and federal governments could.

Meanwhile, failing to manage a supply chain effectively causes serious harm. For example, in 2003 Motorola was unable to meet demand for its new camera phones because it did not have enough lenses available. Also, firms whose supply chains were centered in the Port of Los Angeles collectively lost more than $2 billion a day during a 2002 workers’ strike. In terms of stock price, firms’ market value erodes by an average of 10 percent following the announcement of a major supply chain problem.

The second component is agility, the supply chain’s relative capacity to act rapidly in response to dramatic changes in supply and demand (Lee, 2004). Agility can be achieved using buffers. Excess capacity, inventory, and management information systems all provide buffers that better enable a best value supply chain to service and to be more responsive to its customers. Rapid improvements and decreased costs in deploying information systems have enabled supply chains in recent years to reduce inventory as a buffer. Much popular thinking depicts inventory reduction as a goal in and of itself. However, this cannot occur without corresponding increases in buffer capacity elsewhere in the chain, or performance will suffer. A best value supply chain seeks to optimize the total costs of all buffers used. The costs of deploying each buffer differs across industries; therefore, no solution that works for one company can be directly applied to another in a different industry without adaptation.

Agility in a supply chain can also be improved and achieved by collocating with the customer. This arrangement creates an information flow that cannot be duplicated through other methods. Daily face-to-face contact for supply chain personnel enables quicker response times to customer demands due to the speed at which information can travel back and forth between the parties. Again, this buffer of increased and improved information flows comes at an expense, so executives seeking to build a best value supply chain will investigate the opportunity and determine whether this action optimizes total costs.

Adaptability refers to a willingness and capacity to reshape supply chains when necessary. Generally, creating one supply chain for a customer is desired because this helps minimize costs. Adaptable firms realize that this is not always a best value solution, however. For example, in the defense industry, the U.S. Army requires one class of weapon simulators to be repaired within eight hours, while another class of items can be repaired and returned within one month. To service these varying requirements efficiently and effectively, Computer Science Corporation (the firm whose supply chains maintain the equipment) must devise adaptable supply chains. In this case, spare parts inventory is positioned in proximity to the class of simulators requiring quick turnaround, while the less-time-sensitive devices are sent to a centralized repair facility. This supply chain configuration allows Computer Science Corporation to satisfy customer demands while avoiding the excess costs that would be involved in localizing all repair activities.

In situations in which the interests of one firm in the chain and the chain as a whole conflict, most executives will choose an option that benefits their firm. This creates a need for alignment among chain members. Alignmentrefers to creating consistency in the interests of all participants in a supply chain. In many situations, this can be accomplished through carefully writing incentives into contracts. Collaborative forecasting with suppliers and customers can also help build alignment. Taking the time to sit together with value chain stakeholders to agree on anticipated business plans by shared understanding and rapid information transfers between parties facilitate alignment. This is particularly valuable when customer demand is uncertain, such as in the retail industry (Ketchen et al., 2008).
