AN INVESTIGATION INTO THE EFFECT OF FULL‐SCALE SUPPLY CHAIN MANAGEMENT SOFTWARE ADOPTIONS ON INVENTORY BALANCES AND TURNS

Supply chain management (SCM) software vendors, analysts, and others claim that firms implementing SCM software stand to benefit by being able to reduce inventory holdings and increase inventory turns. We theorize that full‐scale implementations lead to system‐wide inventory optimization, which in turn leads to cost improvement associated with inventory balances and turns. To examine the question, we develop an analytical model of inventory optimization, then analyze the effects of the model with a numerical experiment, and finally confirm the results with an empirical examination. We find that firm‐wide implementation is significant in explaining improvement in inventory metrics, relative to pre‐implementation metrics for our sample. Our empirical tests indicate that implementing SCM software across only a portion of the firm does not impact inventory metrics, but that the scale of implementation does. More precisely, we find that firms implementing SCM software across the entire company significantly improve both inventory turns and inventory as a percent of revenue relative to partially‐implementing firms and non‐implementers.     

THE IMPACT OF POINT‐OF‐SALE DATA INACCURACY AND INVENTORY RECORD DATA ERRORS

The presence or absence of error in point‐of‐sale (POS) data and inventory system records directly affects retailer performance. This study identifies various error sources in retail supply chains and studies the influence of inventory and POS (demand) errors in a simulated retail outlet according to fill rate and average inventory. Other things being equal, we find that inventory record error reduces fill rate more than demand error. This study adds further evidence to other studies that suggest the costs caused by errors in POS systems may be overstated.     

VENDOR‐OWNED INVENTORY MANAGEMENT ARRANGEMENTS IN RETAIL: AN AGENCY THEORY PERSPECTIVE

This paper undertakes two related tasks to augment current understanding regarding vendor‐owned inventory management (VOIM) arrangements implemented in the retail industry. The first task formally juxtaposes three prevalent forms of VOIM arrangements (i.e., Consignment, Pay‐On‐Scan, and Scan‐Based Trading) to one another and identifies three dimensions (i.e., Relevant Data Visibility, Timeliness of Information Release, and Shrink Responsibility) that serve to discriminate among them. The second task applies an Agency Theory lens to uncover differing profiles of characteristics underlying the retailer‐vendor relationship across the Consignment, Pay‐On‐Scan, and Scan‐Based Trading arrangements. These conceptual results contribute to and have implications for the science and practice of VOIM arrangements in the retail industry.     

THE APPLICATION OF EMPIRICAL STRATEGIC MANAGEMENT RESEARCH TO SUPPLY CHAIN MANAGEMENT

Researchers in supply chain management (SCM) have traditionally relied most heavily on the core disciplines of logistics, marketing, and operations; most are less familiar with empirical literature in strategic management. However, with the evolution of logistics into the more interdisciplinary SCM along with increasing attention within strategic management to supply chain issues, recent empirical research in strategy has much to offer. This study reviews and categorizes more than one hundred articles relevant to SCM drawn primarily from top strategic management journals.     

Strategic supply chain choices for multi-channel Internet retailers

Multi-channel retailing—selling through multiple, distinct channels—has been a part of the retail industry as long as there have been main street merchants selling through catalogs. Since the mid-1990s, however, multi-channel retailing has increased dramatically due to traditional retailers selling over the Internet. This trend presents considerable operational challenges because Internet and traditional retail have vastly different demand drivers, product variety issues, optimal inventory configurations, cost structures, supply chain structures, and delivery mechanisms. Consequently, the optimal supply chain configuration for Internet delivery differs considerably from the optimal supply chain configuration for a retail store structure, so designing a supply chain system to serve both channels well is difficult. Accordingly, a set of strategic choices and trade-offs must be made. Here, we present some strategic alternatives.     

Supply chain management and the evolution of the “Big Middle”

The authors define the “Big Middle” as the marketspace in which the bulk of retailers compete for the majority of customers and the preponderance of expenditures occur. Therefore, it is the space in which retailers aspire to exist in their quest for increased revenues, scale economies, and profits. An enduring concept, the Big Middle appears in any economy in which large-scale retailing has developed. In general merchandise retailing in the U.S., there have been three Big Middle subperiods, each defined by a distinct branch of the general merchandising tree; driven by geographic, technological, and socioeconomic changes; and dominated by preeminent retail chains. During the variety store subperiod, the F.W. Woolworth chain dominated. In the national-chain department store subperiod, Sears Roebuck and JCPenney were the primary retailers, and in the modern discounter subperiod, Wal-Mart, Kmart, and Target have emerged as leaders. The authors argue that the development of these subperiods and the success of their major retailers have depended on the efficient and effective flow of merchandise from suppliers to customers. Optimizing this flow always has entailed harnessing current technology, given the geographic and socioeconomic realities of the time. Currently, technology facilitates a comprehensive application of supply chain management, whereas previous technology only permitted a simplified version.

The role and relevance of refocused inventory: Supply chain management solutions

Practitioners and academics continue to note that there is no shortage of inventory in many, if not most, supply chains. Rather, the historical notion holds true: the right product is not in the right place at the right time to meet demand. In order to impact supply chain performance positively, it is necessary to re-address inventory's role and relevance with respect to the development, maintenance, and control of product flows. This paper suggests that examining such flows from a three-fold perspective can be beneficial to firms by providing a framework to assess efforts to achieve lowest total cost and expected customer service.     

THE RELATIONSHIP BETWEEN PURCHASING AND SUPPLY MANAGEMENT'S PERCEIVED VALUE AND PARTICIPATION IN STRATEGIC SUPPLIER COST MANAGEMENT ACTIVITIES

As firms have placed more emphasis on their core competencies and outsourced production and services to suppliers, effective cost management of purchases has become a critical factor in achieving corporate success. The Purchasing and Supply Management (PSM) function is generally responsible for obtaining goods and services from outside suppliers. Techniques such as total cost of ownership, supplier cost structure analysis, and target costing have become important tools for PSM to manage inbound supply costs. Results of a survey indicate that the perceptions of PSM by peer functions and top management, in terms of PSM's importance and accountability, are related to implementing the strategic cost management activities of total cost of ownership, supplier cost structure analysis, and target costing.     

The impact of information sharing and bullwhip effects on improving consumer services in dual-channel retailing

Data sharing among the supply chain players can be an exceptionally significant factor for the retailing industry. In this consideration, an improved retailing methodology for a dual-channel supply chain with a single retailer and manufacturer is built under the bullwhip effect and asymmetric data sharing. Retailer provides asymmetric information to the manufacturer regarding demand to increase their profit. In this scenario, measuring the bullwhip effect is essential in retailing strategy. By adopting an online-to-offline retailing strategy, industries can earn more profit and increase the satisfaction level of customers. The present study focuses on dual-channel retailing, where the demand for the product in both channels varies with the selling price. Keeping in mind the goal of sustainable development, an advanced transportation strategy is utilized in this study, along with some carbon emission costs. Autonomated inspection is utilized to identify defective products. Finally, centralized and decentralized profit functions are formulated for this study. Several cases and numerical examples are provided to validate this study. It is clear from the numerical findings that information sharing within the players provides 1.26% more profit compared to a decentralized case. Due to asymmetric information, which leads to the bullwhip effect, the retailing system faces loss. Thus, information sharing is 0.19% beneficial for dual-channel retailing. Sensitivity analysis for key parameters ensures the findings' applicability in the real world.     

Supply Chain Networks With Multiple Retailers: A Test of the Emerging Theory on Inventories,Stockouts, and Bullwhips

While various approaches to mitigating the bullwhip effect have been proposed, the composition of the underlying supply chain is often taken for granted. This article develops a set of simulation models to investigate changes to the supply chain itself and their impact on the bullwhip effect, on‐hand inventory, and stockouts. It is shown that particular supply chain networks have an impact on the bullwhip effect. Furthermore, the impact of supply chain networks on the bullwhip effect is moderated by the demand forecasting technique used. Finally, supply chain networks, forecasting techniques, and their interactions are found to influence on‐hand inventory levels and stockout rates for firms within the supply chain. Results also suggest that no one particular type of supply chain network dominates in terms of dampening the bullwhip effect, lowering on‐hand inventory levels, or reducing stockout rates. The optimal network depends on the forecasting technique used and other supply chain factors.     

An integrated approach to managing extended supply chain networks

In an effort to improve their competitive position in a rapidly changing marketplace, many companies have replaced their traditional supply chains with extended supply chain networks built on a foundation of supply chain collaboration. These extended networks require the use of decision support tools and technologies to improve both operating efficiencies and customer service, but many companies have struggled to realize the expected benefits of these tools and the increased collaboration. This article recommends that companies adopt an integrated strategy of people, processes, and technology to achieve their competitive supply chain goals. Our recommendation is backed by the results of a survey we conducted of senior-level practitioners concerning the importance and challenges of supply chain collaboration. The article concludes with a set of managerial recommendations to improve a company’s collaborative efforts within its supply chain.     

SUPPLY CHAIN PROCESS INTEGRATION: A THEORETICAL FRAMEWORK

The current study was undertaken to further understanding of supply chain process integration. It is suggested that supply chain integration, the practice of realigning firms' operating structures, should be understood from an internal‐external perspective and a process view. Drawing upon four theories—Strategy‐Structure‐Performance framework, the resource based view of the firm, transaction cost economics, and social network analysis—and combining industry inputs, a theoretical framework of supply chain process integration is developed. It is argued that a firm's strategic priorities are key factors of supply chain process integration. Superior performance is likely to be achieved when necessary supply chain capabilities are developed through supply chain process integration.

Is online-to-offline customer care support essential for consumer service?

Customer satisfaction is the main pillar for convenient and profitable retailing. The retail sector continuously tried to develop new strategies to improve consumer satisfaction. It is impossible to provide each service directly to the consumer by the retailer. In this direction, the retailer establishes customer care to provide the best service to consumers. Consumer care can provide promotional or prevention services, increasing the consumer's satisfaction level. This study is developed to show the impact of retailers' customer care service for an offline-to-online retailing strategy. The demand is consumer support, advertisement, and selling price dependent. For maintaining consumer service, some free home delivery policies are offered, when consumers ordered more than a certain percentage of the amount. Finally, the total profit of this O2O retailing system is calculated by the classical optimization technique. Some special cases are discussed in the numerical section to prove the impact of customer care services. Numerical results prove that customer care support enhances the profit by 48.20%, whereas investment in the advertisement and home delivery strategy helps the retail industry to earn 44.80% and 16.74% more profit, respectively. Finally, from this study, it is clear that customer care activities are essential to increase the profit of the retailing sector.     

How policy is shaping the macro healthcare delivery supply chain: The emergence of a new tier of retail medical clinics

The healthcare industry continues to face substantial pressure to simultaneously improve costs and patient centricity. Much of the focus to date has concerned policy interventions capable of improving these performance measures for traditional healthcare providers, such as hospitals. But recently, nontraditional healthcare providers like Walmart Health and Amazon have made forays into the industry by establishing retail medical clinics (RMCs). These efforts constitute a redistribution of how services are organized across the macro healthcare delivery supply chain. While RMCs stand to bring innovative models of service delivery to patients, the policy environment can both enable and inhibit their involvement in the industry. We develop a framework that explains how structural and conduct regulations have historically influenced demand for and supply of healthcare services. We then describe how these regulatory factors can support nontraditional healthcare providers as they launch innovative service delivery models aimed at efficiency and customer centricity.     

基于组织间供应链网络的民营企业境外拓展能力分析——以浙江省为例

本文在对企业组织间供应链网络及企业国际化文献的研究基础上,提出有关民营企业基于组织间网络的境外拓展能力的假设。在经验研究部分,以浙江省为例,对已经开展境外拓展的民营企业进行问卷调查并检验这些假设。研究结果表明,当前,浙江省民营企业在境外拓展中遇到的障碍依其重要性依次为贸易壁垒、市场信息匮乏和产品缺乏竞争力,而资金匮乏不是其境外拓展中的主要障碍。民营企业在境外拓展过程中应该加强培育和构筑网络关系,而非仅仅依赖企业自身的力量,其中行业组织这一网络成员的作用尤其重要。
