Methods to Our Madness: Adapting Methods to the Changing Nature of Our Problems

Exploring blockchain implementation in the supply chain

Purpose

There is great interest in blockchain in the supply chain yet there is little empirical research to support the consideration of the technology. Ferdows (2018) calls for research aimed at learning from pioneers in the field and Gartner points out that the interest in blockchain holds similarities to the interest surrounding RFID 15 years ago. As a result, there may be opportunities to leverage insights from RFID research to inform the consideration of blockchain. The purpose of this paper is to explore how the Reyes et al. (2016) framework for the implementation of RFID may inform the consideration of blockchain in the supply chain.

Design/methodology/approach

A two-stage approach is used to explore RFID implementation considerations from the Reyes et al. (2016) RFID implementation framework, using an initial exploration of managers interested in blockchain using a focus group and a survey and to more in depth explore three case companies pioneering blockchain.

Findings

Several RFID implementation considerations can inform the consideration of blockchain but there are also differences in considering blockchain. A framework is developed that details considerations found to be relevant by implementation stage.

Originality/value

This paper adds to the limited amount of empirical research on blockchain in the supply chain and advances research beyond the consideration of use cases into the exploration of actual implementation of blockchain in the supply chain. The decision framework developed both leverages and nuances findings from RFID research and can inform managerial decision making. It also adds to research a multi-stage approach to implementation and uncovers rich opportunity to further learn from pioneers.

Sustainable supply chain management: continuing evolution and future directions

Purpose

The purpose of this paper is to update the work of Carter and Easton (2011), by conducting a systematic review of the sustainable supply chain management (SSCM) literature in the primary logistics and supply chain management journals, during the 2010–2018 timeframe.

Design/methodology/approach

The authors use a systematic literature review (SLR) methodology which follows the methodology employed by Carter and Easton (2011). An evaluation of this methodology, using the Modified AMSTAR criteria, demonstrates a high level of empirical validity.

Findings

The field of SSCM continues to evolve with changes in substantive focus, theoretical lenses, unit of analysis, methodology and type of analysis. However, there are still abundant future research opportunities, including investigating under-researched topics such as diversity and human rights/working conditions, employing the group as the unit of analysis and better addressing empirical validity and social desirability bias.

Research limitations/implications

The findings result in prescriptions and a broad agenda to guide future research in the SSCM arena. The final section of the paper provides additional avenues for future research surrounding theory development and decision making.

Originality/value

This SLR provides a rigorous, methodologically valid review of the continuing evolution of empirical SSCM research over a 28-year time period.
