Supply Chain Collaboration,Integration, and Relational Technology: How Complex Operant Resources Increase Performance Outcomes

How firms coordinate efforts to collectively compete as supply chains is a key concern of supply chain management scholars and practitioners. One avenue, the development of collaborative relational capabilities that support supply chain integration, offers promise. However, the effectiveness of collaboration as a supply chain resource has been questioned due to concerns associated with collaborative technologies, and thus prior research has called for a deeper examination of the role that technologies play in facilitating integration. Employing a Service‐Dominant Logic view of hierarchical resources, grounded in Resource Advantage Theory, this research tests a model subsuming relationships between collaboration, integration, and interfirm coordination technologies, and their associated performance outcomes. A sample of 282 supply chain managers from a variety of industries were surveyed, with proposed relationships examined employing structural equation modeling. Test results indicate that collaboration and integration interact to form higher order resources that collectively influence firm performance outcomes through interfirm coordination technologies.     

Understanding Managers’ Reactions to Blockchain Technologies in the Supply Chain: The Reliable and Unbiased Software Agent

Organizations investing in supply chain information systems struggle to ensure successful adoption and implementation. Projects fail because of technical caveats, inability to meet business needs, and poor management of implementation. Implementation of blockchain technologies across a network of supply chain partners is more complex than internally focused technologies. It is necessary for partner firms to implement, contribute, and share information, and employees to actively use the capabilities of the technology to realize potential. Blockchain technologies can substitute for traditional interfirm intermediaries acting as an unbiased software agent embedded in the supply chain network. Understanding managers’ perceptions of and willingness to use blockchain technologies is crucial for successful implementation. Integrating design theory with classic diffusion processes, we conducted a scenario‐based role‐playing experiment with industry professionals to examine managers’ perceptions of blockchain technologies and willingness to use. We find that trustworthiness with regard to competence and perceived distributive justice is the focal drivers of managers’ willingness to use the technology. Additionally, both risk and interactional justice are not drivers of willingness to use blockchain technology despite significant claims to that effect. We provide implications for how managers can leverage these drivers to influence supply chain partners’ willingness to use the technology.

Emerging technologies such as 3D printing promise to transform supply chain design and management. As these new technologies enable inventors to become entrepreneurs, new product introduction cycle times are being reduced and the variety of new products that are introduced through short channels of distribution is increasing. We show that these disruptive forces are growing and may have significant implications for practice, research, and teaching in supply chain management. We identify and elaborate important research questions, calling for theory‐driven research to explain and predict how these phenomena will impact supply chain management.

Tortoise,not the hare: Digital transformation of supply chain business processes

With the rapid development of digital technologies, many supply chain professionals are wondering how to move forward. Three technologies are poised to change supply chain business processes: robotic process automation (RPA), artificial intelligence (AI)/machine learning (ML) and blockchain. Based on interviews with supply chain professionals in 14 large, mature manufacturing and service organizations, we outline the promise of each technology and forecast their broad-scale adoption potential. Organizations should take the following measures to ensure their readiness to adopt and effectively use one or more of these technologies: (1) identify a supply chain technology visionary who can lead through the maze of technologies and the changing digital landscape, (2) develop a digital technology roadmap for their supply chain processes, and (3) update foundational information systems.

RFID Applications for Integrating and Informationalizing the Supply Chain of Foodservice Operators

Abstract

By enabling easier and real-time information sharing among supply chain partners, Internet applications foster and support new forms of collaborative supply chain management (SCM) practices within the foodservice sector. Advances in Radio Frequency Identification (RFID) technologies extend such collaborative SCM practices by increasingly integrating and synchronizing demand and supply chains. The objective of this paper is to investigate and analyze how RFID technologies can seamlessly tie customer interactions with the food supply chain and revolutionize the accuracy, efficiency, personalization-interaction, and security of foodservice marketing, production, and distribution simultaneously. To achieve this, the paper discusses the RFID implementation issues, practices, and benefits within the foodservice sector. The food industry's perspectives on the adoption and benefits of RFID developments are reported by discussing the results of a reality-check study conducted in the Greek foodservice sector.     

THE STOCK PRICE REACTION TO SUPPLY CHAIN MANAGEMENT ADVERTISEMENTS AND COMPANY VALUE

The research examines the stock price reaction to the announcement of the adoption of supply chain management‐enhancing tools and technologies to determine whether there is a significant response from the capital markets. The results show that the adoption of supply chain management‐enhancement tools appears to be value creating. The strength of the stock price reaction is positively related to the degree of certainty regarding the publication date of the publication.
