ENHANCING DELIVERY TIME THROUGH SUPPLIER DIVERSITY IN SOUTH-SOUTH NIGERIA
Abstract
This study examines the impact of supplier diversity on delivery times in construction projects within the South-South region of Nigeria. Supplier diversity, which involves integrating suppliers from varied backgrounds such as local, minority-owned, and small-medium enterprises (SMEs), is proposed as a potential solution to delays in construction completions. The research employs a correlational design and surveys construction project employees from different management levels across several cities in South-South Nigeria. Data were gathered using a validated questionnaire assessing perceptions of supplier diversity and delivery performance. Findings suggest that supplier diversity positively influences delivery time by enhancing operational efficiency, innovation, and resilience. A diverse supplier base mitigates risks associated with supply chain disruptions and improves responsiveness to logistical challenges. The study also identifies challenges in implementing supplier diversity, including higher initial procurement costs and the complexity of managing a diverse supplier base. Despite these challenges, the benefits of supplier diversity; such as improved delivery times, better supplier collaboration, and market expansion, are substantial. The study highlights that expanding the supplier pool not only strengthens the supply chain but also fosters socio-economic development in the region. The research concludes by recommending that construction firms in South-South Nigeria prioritize supplier diversity, invest in capacity-building for smaller suppliers, and improve supplier relationship management. Policymakers are also urged to support local suppliers through favorable policies and infrastructure improvements to enhance the procurement process.
