The construction sector is increasingly challenged by inefficiencies in procurement and coordination across its supply chains, leading to delays, cost overruns, and reduced competitiveness. Digital transformation through e-procurement, combined with strategic supplier involvement, has been proposed to address these challenges. This study examines the impact of e-procurement practices and supplier involvement on supply chain performance within the construction industry. Adopting a quantitative research approach with a cross-sectional survey design, data were collected using a structured, close-ended questionnaire administered to a sample of 277 construction firms in good standing, selected through a simple random sampling technique. Data analysis was conducted using both descriptive and inferential statistics, applying SPSS for preliminary analysis and Partial Least Squares Structural Equation Modeling (PLSSEM) for hypothesis testing. The results indicate a significant positive composite effect of e-procurement practices on supply chain performance, with individual components e-sourcing, e-negotiation, and e-evaluation contributing meaningfully to performance outcomes. Supplier involvement also demonstrates a positive and statistically significant effect, and moderation analysis shows that supplier involvement strengthens the relationship between e-procurement practices and supply chain performance. Additionally, moderated mediation analysis reveals significant indirect effects via esourcing and e-evaluation, though the effect via e-negotiation is not supported. The findings underscore the importance of integrating digital procurement tools with supplier collaboration strategies to enhance supply chain effectiveness in the construction sector. The study recommends that construction firms institutionalize eprocurement practices and deepen supplier partnerships as part of their long-term strategic initiatives to improve operational efficiency and competitiveness.

Manufacturing operations in Ghana continue to struggle with ongoing interruptions across their supply networks, issues that consistently chip away at their operational effectiveness and erode their ability to stay competitive. Even as digital tools become more widespread and the volume of operational information grows exponentially, most companies still haven't managed to properly harness big data analytics for better supply chain coordination and smarter management choices. This investigation set out to examine how big data analytics shapes supply chain results within Ghana's manufacturing landscape, paying special attention to how visibility throughout the supply chain acts as a bridge and how information quality influences that relationship's strength. Drawing on dynamic capabilities theory, information processing theory, and contingency theory as its foundation, the researchers adopted a quantitative methodology. They gathered responses through structured surveys from 272 manufacturing businesses operating in the Greater Accra Region, then processed the information using Partial Least Squares Structural Equation Modelling. What emerged from the analysis shows that big data analytics delivers a measurable and beneficial effect on how supply chains perform. Beyond this direct connection, the study uncovered that visibility across the supply chain serves as a crucial link between analytics efforts and performance gains, primarily because it enables quicker information exchange between partners, smooths out coordination challenges, and sharpens the organization's ability to respond to changing conditions. The evidence further suggests that when information meets high standards for accuracy, timeliness, and relevance, it amplifies the positive impact analytics has on supply chain visibility. From a practical standpoint, the message here is clear: simply pouring resources into analytics technology won't automatically translate into better outcomes unless companies simultaneously build robust systems for seeing across their supply chains and maintain rigorous information standards. By bringing fresh empirical evidence to the table, this work enriches academic conversations while offering concrete direction for manufacturing leaders and policy architects working to strengthen analytical capacities, shore up data integrity, and ultimately push supply chain results and market standing to higher levels.

Boafowa, J.A. In the fast-paced, constantly-changing modern world, gaining and maintaining logistics excellence demands more effort. The main objective of the study is to examine when and how digital innovation capabilities influence firm performance. The quantitative research approach was adopted. Also, explanatory and descriptive research design was employed. Cross-sectional survey strategy was utilized with questionnaire serving as the instrument of data collection. The study adopted convenience sampling and purposive sampling techniques in sampling firms and respondents respectively. The quantitative data collected was analyzed descriptively and inferentially using statistical package for social sciences (SPSS latest version). The findings of the study indicated that digital innovation capabilities are very essential in firm performance. Also, the findings of the study indicated supply chain visibility mediates the relationship between digital innovation capabilities and firm performance. The findings of the study indicated that supply chain responsiveness does not moderate the relationship between digital innovation capabilities and firm performance. The study recommends that firms firm develop dynamic capabilities such as supply chain responsiveness to maximize the benefits of digital innovation capabilities in influencing firm performance.
