This paper examines the advantages and disadvantages of integrating a supply chain, with particular attention to how companies balance time, cost, and scope to maintain high performance. It introduces the Demand Driven Supply Network (DDSN) framework developed by AMR Research and discusses the Hierarchy of Supply Chain Metrics as a tool for measuring tactical and strategic performance. The paper also analyzes the top ten supply chain innovations identified by Supply Chain Digest — including the Toyota Production System, Universal Product Codes, and the Ford assembly line — exploring the unifying threads among these innovations and their implications for the future of supply chain management.
The paper effectively layers two analytical frameworks — the DDSN model and the Hierarchy of Supply Chain Metrics — to move from a broad organizational concept to a measurable, tiered set of performance indicators. This technique of scaffolding one framework on another shows how theoretical constructs can be operationalized, which is a strong move in applied business writing.
The paper opens with an introduction that establishes the importance and complexity of supply chain management. It then presents a detailed pros-and-cons table followed by prose analysis. The third section evaluates the top ten supply chain innovations and introduces the DDSN and Hierarchy of Supply Chain Metrics frameworks. A brief conclusion synthesizes the findings. The structure moves logically from diagnosis (integration trade-offs) to historical context (innovations) to measurement (metrics hierarchy).
Of the many processes, systems, and platforms in any company, its supply chain is the most critical for continually meeting customer expectations and delivering high-quality products and services. Managing supply chains so they are demand-driven and meet and exceed customer expectations is essential if a business is going to succeed over the long term and earn trust through continual, predictable execution to customer requirements (Ellinger, Shin, Northington, et al., 2012). The challenge, however, is that supply chains are often very complex, multiple layers deep, requiring an intensive amount of effort to keep coordinated and synchronized while also staying aligned with rapidly changing product requirements over time. Adding in the need to launch new products quickly to attain revenue growth, and the full complexity of supply chain management becomes clear.
The intent of this analysis is to evaluate the pros and cons of integrating a supply chain and specifically to evaluate how companies manage the inevitable conflicts between time, cost, and scope to ensure a consistently high level of supply chain performance and product quality. The highest-performing supply chains are able to transform information and insight into intelligence that is immediately used to accelerate and streamline supply chain performance (Kogut, 2000). The Toyota Production System is a case in point, relying on an advanced series of processes for interpreting supply chain performance and creating plans and programs that compensate for variations in customer demands and the ability of suppliers to react accordingly (Shook, 2009). The second section of this analysis concentrates on the top ten supply chain innovations of all time as identified in the Supply Chain Digest video. The unifying threads among these ten innovations are analyzed with emphasis on what they mean for the future of supply chain management.
Reducing costs and complexity, managing the constraints of project- and make-to-stock manufacturing more effectively, and increasing the speed of new product development and launch are just a few of the advantages of integrating a supply chain. What unifies the many advantages of supply chain integration is the ability to become more customer-centric — driven not by internal forecasts or a myopic view of cost reduction, but by a commitment to greater customer responsiveness, meeting and exceeding expectations in the process (Ellinger, Shin, Northington, et al., 2012).
Research firm AMR Research defined the many factors that contribute to a more customer-centric and demand-driven supply network as the formation of a Demand Driven Supply Network (DDSN) (Friscia, 2005). Central to the DDSN concept is the unification of all aspects of a supply chain around the common goal of meeting customers' demands in a timely, complete, accurate, and cost-effective manner. The DDSN has since been used as a framework for quantifying how much an integrated supply chain can deliver in terms of economic value to an enterprise.
One of the most significant findings from the AMR Research studies of the DDSN concept was how an integrated supply chain creates knowledge over time, and how this knowledge becomes fuel for even greater levels of competitive differentiation and value. The well-known study of the Toyota Production System by Dyer and Nobeoka (2000) illustrates how Toyota continues to succeed in transforming information and intelligence into a competitive advantage by increasing the speed and accuracy of production. Dyer and Nobeoka noted that information and intelligence became more valuable than cash as a means for suppliers to coordinate with each other within the TPS framework (Dyer & Nobeoka, 2000). With so many advantages to integrating a supply chain, it is understandable that enterprises continue to seek expertise in this area to increase process, product, and project performance.
The following table compares the key pros and cons of integrating a supply chain.
Greater responsiveness to customers, including the ability to better predict when a customized order will be shipped (Ellinger, Shin, Northington, et al., 2012).
Greater supplier collaboration and reduction in new product introduction timelines, leading to greater revenue generation over time (Dyer & Nobeoka, 2000).
Closer coordination between distribution and selling networks, manufacturers, and suppliers, resulting in more accurate forecasts and greater sales (Harrington, 1999).
Reduced costs through the use of advanced supply chain coordination and costing, including the ability to better manage bills of materials in a production environment (Abu-Suleiman, Boardman, & Priest, 2004).
Broader distribution of risk across the entire supply chain by ensuring every level has greater visibility into customer demands, seasonality, and customization requirements over time.
More effective definition of inventory management, supplier quality, purchasing costs, and cost details including plant utilization and cycle times (Hofman, 2004).
Better management and prediction of perfect-order fulfillment — getting the right product to the right customer at the right time across all distribution channels (Hofman, 2004).
Greater financial visibility into a company's performance, including more effective reduction of Days Sales Outstanding (DSO) and reworked orders due to lack of integration (Hofman, 2004).
More efficient adoption of new technologies to streamline the supply chain management process once manually-based processes are in place.
Greater supply chain optimization through the use of advanced technologies once a supply chain has been integrated and is functioning to deliver products on time.
Enhanced quality management, including the ability to conduct supply chain quality audits and use the data to better manage inbound shipments; as technologies are added, quality audits can accelerate acceptance and rejection decisions and guide suppliers to higher quality levels in real time (Abu-Suleiman, Boardman, & Priest, 2004).
Faster information and knowledge exchange across the supply chain, leading to higher quality and greater agility in responding to changing market requirements (Dyer & Nobeoka, 2000).
Costs can become excessive if the underlying assumptions regarding the structure and approach of the integrated supply chain are not well defined from the outset. A poorly designed framework can actually make a supply chain more ineffective and inefficient than it was before automation (Abu-Suleiman, Boardman, & Priest, 2004).
Integrated supply chains often deliver only a subset of the financial results needed to define the hierarchy of supply chain metrics in total, which can lead to an incomplete picture of an enterprise's operation and create greater confusion than a manually-based system (Hofman, 2004).
Lack of adequate change management programs to bring suppliers onboard and ensure effective use can result in costs that exceed those of the manually-based system the integration was designed to replace (Dyer & Nobeoka, 2000).
Continual supplier turnover in high inventory velocity industries can lead to significant shifts in the overall design of the supply network and inconsistencies over time that must be compensated for within the integrated system.
Inconsistent performance on items critical to customer needs can generate even greater customer dissatisfaction, as an integrated supply chain may slow execution of specific tasks if not planned and implemented carefully.
Annual maintenance costs for enterprise software and the headcount needed to manage the supply chain network effectively are often variable and unpredictable, and can escalate quickly if an integration strategy is not well planned and executed.
Lack of full supplier participation — or the inclusion of only a specific subset of transactions in the formalized system — leads to confusion over actual supply chain performance over time (Abu-Suleiman, Boardman, & Priest, 2004).
Confidentiality risks arise when a manufacturer attempts to build a thorough collaborative network, as companies may be required to disclose sensitive data to suppliers under non-disclosure agreements that are at times violated. Apple's efforts to keep iPad development confidential within its supply chain are a notable example of this challenge.
Continual supplier churn in commodity industries can cause integrated supply chains to operate at a sub-optimal level, sometimes performing worse than the manually-based systems they replaced.
Advanced supply chain strategies such as Vendor Managed Inventory (VMI) and Collaborative Planning, Forecasting and Replenishment (CPFR) require a highly integrated supply chain at an electronic level that many suppliers lack the IT capacity to support.
Future technology developments in material handling and inventory management — including Radio Frequency Identification (RFID) — are more easily accomplished with a smaller set of suppliers than with a large, highly integrated network. The greater the network's complexity, the more challenging it becomes to keep the entire system platform current across all suppliers.
The top ten supply chain innovations of all time identified in the Supply Chain Digest video are all centered on the need for greater accuracy, efficiency, and more cost-effective approaches to managing variation in demand. While technologies have been developed and, in certain cases, are integral to the development and sustaining of these innovations, technology is not critically important to each one individually. Instead, technology has served as an accelerator of these innovations, amplifying their impact and contribution to the companies that rely on them.
Supply Chain Digest lists Taylorism (the scientific approach to manufacturing), 3M load centers, Distribution Requirements Planning (DRP), the FedEx tracing system, Universal Product Codes (UPC), the Ford Motor Company assembly line, Economic Order Quantities (EOQ), ocean shipping containers, the P&G continuous replenishment program, and the Toyota Production System as the most valuable supply chain innovations of all time. The TPS has proven to be one of the most effective innovations for managing the diverse nature of supplier integration and the difficult task of ensuring supply chain coordination and collaboration across diverse network participants (Dyer & Nobeoka, 2000). It has also demonstrated that the greater the level of shared risk and insight into demand-centric information, the greater the level of shared task ownership (Shook, 2009), which in turn causes supply chain information to become a competitive asset worth more than cash over time (Dyer & Nobeoka, 2000).
These factors taken together all provide insights into how the innovations mentioned in the Supply Chain Digest video contribute to a more profitable and efficient enterprise supply chain management system. Unifying these elements with analytics that span the tactical to the strategic is essential for any organization seeking sustainable competitive advantage through supply chain excellence.
