Purpose <p>The purpose of this research is to understand how three important digital technologies, namely big data analytics, blockchain technology, and internet of things (IoT) influence the capabilities of manufacturing companies in Saudi Arabia from the perspective of the dynamic capabilities view. The research assumes that the production system sustainability (PSS) plays a mediating role , and that the ethical culture influences the relationship of PSS and CP.</p> Methodology <p> This study was conducted using a quantitative survey design. Data were collected through a structured survey distributed to manufacturing companies within Saudi Arabia, yielding responses from an initial sample of 550 potential participants (426 total responses). The usable sample consisted of 390 completed surveys and were tested by using SmartPLS.</p> Key findings <p>The results confirm that BDA and BCT significantly contribute directly to the sustainability of the production systems. Furthermore, the study demonstrates that sustainability of the production systems mediates the relationship between the three digital-enabling technologies and competitive performance. In addition, the ethical culture has a strong moderating effect on the relationship of the sustainability of the production systems and competitive performance.</p> Implications and value <p>Dynamic capabilities theory can be extended to include BDA, BCT, and IoT as explicit input factors, and sustainability of the production systems as the durable configured operational capability. Managers in Saudi Arabia should focus on creating data-driven cultures, employee training that enables employees to manage the ethical dimensions of technology, and establishing ethical governance to maximize competitive advantages associated with sustainability initiatives. Future research should increase geographic diversity and examine other emerging technologies.</p>
