Abstract:
This thesis explores specific tensions within sustainable supply chains (SSCs), focusing on disruptive multiple-crises, also known as VUCA (volatile, uncertain, complex and ambiguous) events such as Covid-19 and the Russia-Ukraine conflict. A systematic literature review (SLR) probes these tensions, and data have been analysed through semi-structured interviews and examination of Blockchain blogs, utilising qualitative research methods. Three inter-connected research studies form the core of this thesis. The first study reveals various barriers and tensions challenging SSCs, especially during disruptive events. An SLR highlights the significant tensions affecting SSCs, synthesizes them, and underlines directions for future research. The second study investigated how SSC leaders tackle the unique challenges presented by the global pandemic. Interviews with New Zealand executives offer vital insights and critical adaptation strategies for SSCs. This study presents a framework that explains strategic adaptations around VUCA event challenges, recommending fundamental paradigm shifts for improved decision-making, resource allocation, and operational flexibility. The third study brings a fresh perspective by viewing SSCs as value-co-creating ecosystems. It promotes using Blockchain to alleviate some of the identified tensions. The richness of this sphere is highlighted through an online content analysis of Blockchain blog discourse, which supplements the academic discussion and proposes strategies based on cross-disciplinary concepts. Set against the turbulent backdrop of multiple-crises VUCA events, this thesis aims to tackle the global challenges SSCs face. It breaks down these challenges, extracts critical lessons, and outlines paths forward for SSCs, concluding with the limitations of this research and directions for future investigation. In summary, this thesis integrates a range of methodologies and conceptual frameworks, advancing our understanding of sustainability within SSCs. It contributes practical managerial insights and leverages both traditional and emerging research avenues, offering a nuanced picture of sustainability in the SCs ecosystem.
