    SPIDER,
    Application for collecting, analyzing, and centralizing industrial project performance and progress data, to improve project activity management and monitoring (from design studies to construction), local and HQ management decision-making, relationships with contractors, and knowledge sharing between different projects. It also aims to replace the reporting process focused on paper documentation with a fully digitized process. Thus, the time previously spent on data collection and manipulation is now dedicated to analysis and more informed decision-making. This results in increased productivity for teams and financial savings for the Company.
