While traditional procurement has often focused on cost control and auditing, there is an increasing necessity to pivot toward more collaborative, innovation-driven, and sustainable practices. This dissertation critically evaluates the SRM practices of GlaxoSmithKline (GSK) to identify how the firm can better leverage its supplier relationships to enhance sustainability, resilience, and ethical performance. Adopting an interpretivist and inductive case study design, this research analyzes secondary qualitative data, including GSK’s sustainability and business performance reports, supplier codes of conduct, and industry analyses. By synthesizing theoretical frameworksincluding the Kraljic Portfolio Model, the Triple Bottom Line, and resilience literaturethe study examines the integration of sustainability and resilience into GSK’s supplier governance. The findings indicate that while GSK exhibits a mature governance structure for compliance and risk management, its approach remains predominantly transactional and control-oriented. Significant gaps exist in fostering deep relational collaboration and co-innovation, which are essential for meeting ambitious environmental goals and navigating supply chain shocks. To bridge these gaps, the dissertation proposes a transition toward a more collaborative and digitally enabled SRM model. Recommendations focus on moving beyond compliance-based monitoring to implement joint capability building, strategic knowledge sharing, and the integration of sustainability and resilience metrics into supplier performance scorecards. This research contributes to SRM theory by extending its application to a highly regulated, sustainability-demanding industry and provides actionable managerial insights for pharmaceutical procurement professionals.35enSupplier Relationship Management (SRM)Pharmaceutical Supply ChainSustainable Supply Chain Management (SSCM)Supply Chain ResilienceStrategic SourcingGlaxoSmithKline (GSK).Thesis
