- <p>Process-control systems are essential for enhancing efficiency and reducing risks in various industries, including telecommunications engineering. In South Africa, these systems have been implemented to manage operational processes more effectively. This study employs a difference-in-differences (DiD) econometric model to analyse the implementation of process-control systems in South African telecommunications, aiming to quantify their effect on reducing operational risks. The DiD model will compare treated and control groups over time to isolate the impact attributed to system changes. The analysis revealed a significant reduction in risk levels by approximately 30% for the telecommunication networks implementing process-control systems compared to those without, indicating positive outcomes from these interventions. This study validates the efficacy of DiD methodology for evaluating the impact of process-control systems on operational risks. The findings suggest substantial benefits in terms of risk reduction and support further implementation strategies. Telecommunication companies should consider adopting process-control systems based on this evidence, alongside continuous monitoring and improvement to maximise their risk mitigation capabilities.
