Implementing Blockchain Technology for Transparent Procurement Processes in Supply Chains

Thesis Abstract

The increasing complexity and opacity of procurement processes within global supply chains have raised significant concerns regarding transparency, accountability, and trust among stakeholders. Traditional procurement systems often encounter challenges such as fraud, misreporting, delays, and lack of real-time traceability, which compromise the integrity and efficiency of supply chain operations. This study aims to explore the potential of blockchain technology as a transformative solution to enhance transparency and integrity in procurement processes across multinational supply chains. The specific objectives are to (1) assess the current limitations of conventional procurement systems, (2) analyze the capabilities and suitability of blockchain technology for procurement transparency, and (3) develop a conceptual framework for the implementation of blockchain-based procurement systems in practice. Employing a mixed-method research design, the study integrates qualitative case studies with quantitative surveys to provide a comprehensive understanding of blockchain’s applicability in procurement. The qualitative component involves in-depth interviews with 20 supply chain executives from manufacturing and logistics firms that have piloted or adopted blockchain solutions. The quantitative component registers a stratified random sample of 150 procurement professionals within the manufacturing sector across three continents, utilizing a structured questionnaire designed to measure perceptions of blockchain benefits, perceived barriers, and readiness for adoption. Data collection instruments include semi-structured interview protocols and a validated survey instrument with a Cronbach’s alpha of 0.87, ensuring reliability. The primary data analysis employs thematic analysis for qualitative data and descriptive statistics, inferential statistical tests such as multiple regression analysis, and structural equation modeling (SEM) for quantitative data, allowing for the examination of relationships between variables such as technological readiness, perceived benefits, and organizational readiness. The expected findings are that blockchain technology significantly enhances the transparency, authenticity, and traceability of procurement transactions, which in turn reduces fraud, delays, and dispute occurrence. The study anticipates identifying key barriers to blockchain adoption, including technological complexity, cost considerations, and lack of standardized protocols. Additionally, the research hypothesizes that organizational readiness and perceived ease of use are positively correlated with blockchain adoption intentions. The SEM analysis is expected to elucidate the causal pathways among these variables, contributing to a theoretical understanding of technology acceptance in procurement. This research contributes to existing knowledge by empirically validating the applicability of blockchain within supply chain procurement contexts and developing a tailored conceptual framework for implementation. It bridges the gap between theoretical potential and practical application by providing strategic insights for policymakers, industry leaders, and supply chain managers seeking to harness blockchain for transparency. The findings have implications for designing scalable, secure, and standardized blockchain solutions that are aligned with organizational capabilities and stakeholder expectations. The main conclusion underscores that blockchain technology holds considerable promise for revolutionizing procurement transparency, but its success depends on addressing critical barriers such as technological maturity and stakeholder alignment. Based on these conclusions, the study recommends fostering collaborative industry standards, investing in capacity building for blockchain integration, and developing clear regulatory frameworks to facilitate widespread adoption. Future research avenues suggested include longitudinal studies to assess the impact over time and sector-specific evaluations to customize blockchain solutions for diverse supply chain environments. The study ultimately advances the understanding of digital transformation in procurement, facilitating more transparent, accountable, and efficient supply chains in the global context.
