Technology adoption and effective governance are increasingly important organizational capabilities for improving the efficiency, accountability, and competitiveness of agricultural cooperatives. This study examined the relationship between technology adoption, governance practices, and the operational performance of dairy cooperative societies in Kiambu County, Kenya. A descriptive cross-sectional research design was employed, covering 19 dairy cooperative societies. Data were collected from managers, board members, and cooperative-member employees using structured questionnaires. Of the 78 targeted respondents, 69 participated, yielding an 88.46% response rate. Primary survey data were complemented by 2024 milk production and milk payment data obtained from the Kenya Dairy Board. Technology adoption was assessed using indicators including electronic payment systems, dairy management technologies, computerized records, and real-time data capture, while governance practices were assessed through board structure, accountability, leader-member communication, and member participation. Operational performance was measured using an Operational Performance Index based on annual milk production volume and average milk payment per litre. Pearson correlation and multiple linear regression analyses were conducted, with aggregation strategies included as a control variable. The regression model was statistically significant and explained 85.7% of the variation in log operational performance (R² = 0.857, F(3,15) = 29.874, p < 0.001). Technology adoption was positively and significantly associated with operational performance (β = 1.070, p = 0.042), while governance practices also showed a positive and significant association (β = 0.381, p = 0.012). Consistent with these results, technology adoption had a strong positive correlation with operational performance (r = 0.797, p < 0.01), while governance practices had a substantial positive correlation (r = 0.649, p < 0.01). Qualitative findings indicated that digital payments, computerized records, digital communication, and real-time data systems improved record accuracy, payment efficiency, information flow, monitoring, coordination, and decision-making. Effective governance strengthened accountability, board oversight, transparency, member participation, and resource management. The findings further suggest that technology and governance operate as complementary organizational capabilities, with their benefits depending on adequate infrastructure, financial resources, staff competencies, effective leadership, and member engagement. The study recommends an integrated approach combining affordable and scalable digital technologies with governance capacity building, transparent communication, effective board oversight, member participation, and continuous staff development. Given the cross-sectional design and the small number of cooperative-level observations, the findings demonstrate significant associations rather than definitive causal effects.
