Complex supply networks feature many inter-connected and geographically distributed partners. Many of these partners are beyond the direct realm of the company, making the management of sustainability a difficult task. Inevitably, this research aims to explore how blockchain technology can facilitate sustainability initiatives across multi-tier supply networks. The findings suggest that blockchain can enhance the visibility of suppliers’ sustainability practices. Managers will have increased transparency and traceability of their multi-tier supply networks, which will eventually reduce the cost of monitoring a large number of geographically distributed suppliers. Furthermore, information can be shared with different stakeholders to increase credibility and legitimacy.

Much of the existing literature on the social aspects of sustainability in the supply chain has focused on dyadic buyer-supplier relationships. However, supply chains are much more extensive, featuring multi-tiered systems consisting of many interconnected sequential and parallel dyadic relationships; therefore, a more expansive and holistic approach to exploring the management and integration of social sustainability standards across the extended supply chain is desirable. This research attempts to help fill this void and considers the extent to which a series of sequential upstream and downstream supply chain partners, rather than only a focal organization’s immediate suppliers and buyers, influence the formulation process of the social aspects of a sustainability strategy and the deployment of associated practices across the extended supply chain. Findings in the literature indicate that, inter alia, sustainability efforts in the supply chain are likely to be guided by stakeholders’ sustainability desires/requirements, the geographical location of buyers and suppliers and the associated sustainability enforcement regulations and cultural norms, and the volume of trade between the buyer and supplier. This paper uses the results gleaned from a review of the literature to propose a conceptual framework for selection of sustainability strategy across the multi-tiered supply chain. Finally, we introduce a conceptual approach to the process of implementing and deploying the social aspects of sustainability strategies and practices across the supply chain using an integrated social-sustainability information management system (ISIMS).

Purpose As service organizations move toward the open system strategic customer orientation, they need to ensure consistency among competitive methods, performance measures and strategies utilized. This paper aims to examine the relationships among these important facets of today’s service organizations. The study at hand examines the relationship among competitive methods, implicit strategy and performance measures used by Portuguese service organizations. Design/methodology/approach This research uses a survey-based methodology. Factor analysis, cluster analysis and regression analysis procedures are used to analyze the collected data from Portuguese service organizations. Findings Based on the results of this study, it appears that some of the studied service organizations are steadily moving toward the open system mode of strategy, competitive methods and performance measurement. However, the majority of the service organizations examined appeared to be in a state of strategic confusion, as they appear to lack the consistency among competitive methods, performance measures and desired strategic orientations. Research limitations/implications The sample used in this study is specific in nature, as it includes only Portuguese service organizations. Therefore, the results of this study should be interpreted with caution. Future research in other cultural service settings is recommended. Such research should emphasize the exploration of theoretical frameworks, which tend to practically integrate competitive methods, performance measures and strategic orientation. Practical implications This study has direct practical implications for service managers, as they attempt to integrate their organizational systems. As such, the research in this study paves the way toward the practical integration and consistency among competitive methods, performance measures and strategic orientations needed to enhance the customer orientation. In this context, such integration and consistency are essential to enhance the strategic competitiveness of today’s service organizations operating in a dynamic marketplace. Originality/value This research combines bodies of knowledge dealing with competitive methods, performance measures and their impact on strategic orientations. The conceptual framework offered in this research attempts to facilitate the understanding for consistent practice pertaining to the competitiveness of the open system service organization in a dynamic environment. Such consistency is essential to the competitiveness of the organization in a dynamic environment.
