Computer System
We have a management information system (Enterprise resource planning or "ERP") that integrates and manages the company's administrative business and support processes: Finance, Accounting, Human Resources and Logistics (IT). The ERP and satellite systems are located in Chile. However, each subsidiary or commercial office has its own ERP which is then consolidated into the information system in Chile. In addition, we have industrial systems such as: plant operation, extraction and maintenance (OT) that are part of the operation.
The information system is mainly used for finance, accounting, human resources, supply and inventory tracking, billing, quality control, research activities and control of the production process and maintenance. The main data processing center is located in our offices in Santiago de Chile, Antofagasta and in our international subsidiaries, that are interconnected through the telecommunications network, data clouds and services.
The use of cloud technologies allows us to be compatible with new business processes and respond quickly and at low cost to the changing conditions of our business and the market.
To ensure the reliability of our client services, we have adopted an information security and cybersecurity framework based on international norms and standards. This information security framework is focused on the protection and safeguarding of critical business assets and requires a continuous work on raising the awareness among our users on the best uses of processes and technology.
