Monitoring and mentoring strategies for diffusing sustainability in supply networks

Purpose This paper aims to investigate the impact of monitoring and mentoring strategies on sustainability diffusion within supply networks through focal companies and how suppliers engage in implementing these strategies. Design/methodology/approach The paper reports on three in-depth case studies conducted with focal companies and their suppliers. An interaction approach was adopted to guide the analysis of focal companies' strategies for implementing and diffusing sustainability in supply networks. Findings The monitoring strategy impacts sustainability diffusion at the dyadic level, while the mentoring strategy is a prerequisite for the diffusion of sustainability at the supply network level. The findings suggest that coupling monitoring with mentoring can lead to diffusion beyond first-tier suppliers. Interaction intensity, supplier proactiveness and mindset change facilitate sustainability diffusion in supply networks. Research limitations/implications The authors suggest more research be conducted on specific practices within monitoring and mentoring, as some of these imply very different levels of commitment and interaction. Practical implications The paper suggests that in the future, companies will be increasingly called upon to adopt cooperative initiatives to enable the diffusion of sustainability in supply networks. Originality/value The contribution of the paper lies in its identification of the impacts of monitoring and mentoring strategies on the diffusion of sustainability in networks, revealing different supplier engagement in these strategies, which may foster or hinder sustainability diffusion.
