Design, implementation and evaluation of a cooperative procurement platform for SMEs in urban markets

Thesis Abstract

Cooperative procurement offers a strategic response to the purchasing constraints faced by small and medium-sized enterprises (SMEs) operating in dense urban markets, where individual firms often encounter limited bargaining power, fragmented supplier relationships, and rising input costs. This study addresses the gap by designing, implementing, and evaluating a digital cooperative procurement platform aimed at aggregating demand, standardizing specifications, and enabling bulk purchasing for urban SMEs. The aim is to enhance procurement efficiency, reduce transaction costs, and improve supplier diversification while maintaining service quality and compliance with urban market regulations. Specific objectives are (i) to architect a scalable platform architecture that supports dynamic aggregation of SME orders, supplier onboarding, and transparent pricing; (ii) to implement governance mechanisms that ensure equitable participation, trust, and data security; (iii) to evaluate operational performance through a controlled pilot in three metropolitan districts involving 180 participating SMEs and 25 supplier entities; (iv) to assess impacts on cost savings, lead times, and supplier satisfaction; and (v) to develop a framework linking platform features to organizational outcomes and long-run adoption. Methodologically, the study adopts a mixed-methods design grounded in transaction cost economics and resource-based view theories to explain efficiency gains and capability development. The population comprises registered SMEs in urban manufacturing, wholesale, and retail sectors within the city. A two-stage sampling approach selects 60 SMEs for the pilot group and 60 SMEs as a non-participating comparison group, with 60 SMEs as a diversified non-random sample to capture contextual heterogeneity. Supplier participants total 25 entities across food, consumables, and packaging categories. Data collection instruments include a platform usage log (capturing order frequency, size, and fulfillment times), semi-structured interviews with SME managers and supplier coordinators (n=40), and a structured survey measuring perceived value, ease of use, trust, and satisfaction (n=120). Validity and reliability procedures encompass content validity checks by a panel of procurement scholars, pilot testing, Cronbach’s alpha assessment for scales (>0.70), and triangulation across quantitative and qualitative data. Data analysis employs descriptive statistics and inferential tests including difference-in-differences for cost and lead-time improvements, and regression analyses to identify determinants of platform adoption and user satisfaction. The qualitative component undergoes thematic analysis following Braun and Clarke to extract insights on governance, trust, and coordination challenges, complemented by a cross-case synthesis of SME experiences. An analytical framework integrates structural equation modelling to test relationships among platform usability, perceived value, and adoption intent, with model fit indices (CFI > 0.90, RMSEA < 0.08) reported. Key expected findings include (i) statistically significant reductions in average procurement cost per unit and total lead time for pilot participants relative to controls; (ii) enhanced order consolidation and supplier diversification leading to improved procurement reliability; (iii) positive associations between perceived usefulness and ease of use with intention to continue platform use; (iv) governance features such as transparent pricing, credentialing, and dispute resolution correlating with higher trust and participation rates; and (v) variations in benefits across SME size, sector, and district, indicating contextual contingencies. The study anticipates that the cooperative procurement platform will enable SMEs to achieve economies of scale previously unattainable individually, while suppliers gain more predictable demand and reduced transaction costs. The contribution to knowledge rests on (1) a rigorous design and empirical evaluation of a scalable cooperative procurement solution for urban SMEs, (2) an integrated theoretical model linking transaction cost economics and social capital considerations to digital procurement adoption, and (3) practical governance and architectural guidelines for co-operative platforms in dense urban economies. The study concludes that, when paired with robust governance, standardization of specifications, and transparent pricing, the platform can deliver material improvements in efficiency and supplier relationships for urban SMEs. Recommendations include expanding pilot coverage to additional districts, incorporating AI-driven demand forecasting and supplier rating systems, establishing formal partnership agreements with municipal procurement agencies, and developing a replicable implementation roadmap for other cities targeting SME procurement resilience and inclusive urban growth.
