Abstract

Purpose

More than two decades long technological improvements in information sharing have not yet ensured a flawless execution of vendor managed inventory (VMI) and left interested parties wondering about the reasons of poor results. Although VMI is a collaborative tool, the relational factors in a VMI setting have not received enough attention due to challenges in obtaining relational buyer-supplier data in addition to extant focus on analytical approaches. The purpose of this paper is to investigate post-implementation relational factors in order to extract relevant insights.

Design/methodology/approach

Accounting for the duration of the VMI relationship, the authors focus on two dimensions of VMI often ignored post-implementation: dependence of the buyer on the VMI-supplier and trust of the buyer in the VMI-supplier. Cross-sectional data were collected using a survey collected from distributors mostly in auto and electrical supply industries, which have their inventories managed by manufacturers through VMI arrangements. The sample was obtained from a leading third-party VMI-platform service provider that serves thousands of distributor-manufacturer locations with billions of dollars in sales orders. Multiple ordinary least squares regression has been used to test the hypotheses.

Findings

This paper provides empirical support that in the post-implementation stage, longer VMI relationships are associated with higher distributor dependence on the manufacturer. In addition, too much dependence could actually hurt the distributor’s trust in the manufacturer.

Practical implications

The authors propose that distributors maintain some of the purchasing and inventory management skills in house to limit their dependencies on the manufacturers. Manufacturers should also invest in trust-building activities, such as regular communications with distributors.

Originality/value

This is the first study providing empirical evidence on the positive association between length of VMI relationship and buyer dependence on the supplier, and curvilinear dependence-trust link in a post-implementation VMI context.

Abstract

Purpose

Third-party logistics (3PL) companies have experienced an explosion of volume during coronavirus disease 2019 (COVID-19). Special tiers have been introduced to provide differentiated levels of service to the customers. However, such changes in an organization reveal and intensify tensions known as paradoxes. The purpose of this research is to identify what paradoxes emerged or have become more salient specifically due to COVID-19 in 3PLs' ground operations and how they are dealt with by ground operation managers.

Design/methodology/approach

This is a qualitative study conducted in two phases. Phase one utilizes a questionnaire approach to identify the paradoxes within the 3PLs operating in the USA. Phase two, conducted six months after phase one, follows an in-depth one-on-one interview approach. NVivo 12 is employed to analyze the interview data.

Findings

The results show that new paradoxes did in fact emerge due to the COVID-19 and are mostly related to the performing paradox category. Findings from in-depth interviews show that the 3PL managers focus on keeping safety as priority to manage COVID-19 related paradoxes, along with modifying operational plans, improving communication, investing in training, optimizing hub network, introducing modified/new methods and adapting modified human resource policies.

Originality/value

This paper is among the first known to identify paradoxes within the 3PL operations during the COVID-19 and provides insights into how these paradoxes are dealt with at mid-management level. Findings of this study provide foundations for the development of a theoretical framework on handling paradoxes within 3PLs.

Abstract

Purpose

The purpose of this paper is to examine the impact of cloud computing (CC) use on collaboration and its ultimate impact on the agility of humanitarian supply chains. Further, this paper aims to analyze the moderating role of inter-organizational trust in the relationship between CC use and collaboration.

Design/methodology/approach

This paper provides an empirical assessment of CC use based on an interview analysis of 19 individuals from humanitarian organizations. A survey questionnaire is later used with 107 participants from US relief organizations. Partial least squares test is used to examine the relationships depicted in the conceptual model.

Findings

The results provide an account of how CC is used in a humanitarian context. Further, the results indicate that CC use has a positive and significant impact on collaboration between humanitarian organizations and their suppliers. Collaboration is found to be significantly positively associated with agility in humanitarian organizations.

Research limitations/implications

No study, to the best of the authors’ knowledge, has empirically assessed the impact of CC use on humanitarian supply chain collaboration. This will be the first study to empirically analyze the relationships between CC use, inter-organizational trust, collaboration and agility in a humanitarian context.

Practical implications

This study provides a theoretically and empirically validated model depicting the relationships between CC use, collaboration, agility and inter-organizational trust in humanitarian supply chains. Humanitarian organizations can use these findings to optimize agility.

Originality/value

This study contributes to supply chain management research, particularly humanitarian supply chain management knowledge, by empirically examining the usefulness of CC use on collaboration and agility in the supply chain.

Abstract

Purpose

The purpose of this paper is to introduce a game-like decision tool – “Greatest Good Donations Calculator (GGDC)”, which has been collaboratively developed by scholars from the University of Rhode Island and the USAID Center for International Disaster Information.

Design/methodology/approach

The study is grounded in two streams of research – human learning through games and systems dynamics literature. The problem of “unsolicited in-kind donations” is discussed followed by the development of the GGDC.

Findings

The GGDC is a game-like decision tool that informs users on some of the complexities associated with humanitarian supply chains, and the ineffective nature of unsolicited in-kind donations compared to monetary contributions when sent in response to international disasters.

Research limitations/implications

The GGDC could be made more interactive and playable that could improve user engagement. The GGDC’s value to the humanitarian community and public could also be measured in other ways, such as surveys and A/B split tests after a major donation campaign.

Practical implications

Games, simulations and game-like tools could successfully be used to educate donors about smart compassion.

Social implications

Humanitarian researchers and scholars should consider more games to motivate/drive social change in the humanitarian world.

Originality/value

This is the first paper to introduce the GGDC to the humanitarian logistics community with detailed content about positioning the study in the academic literature, and stages of development. Scholars, searching to adopt games or developing new games for the humanitarian world may find the information valuable. The GGDC is a unique example of federal government – academia collaboration in raising public awareness of the unsolicited good donations problem.
