Gathering event-driven data, in real-time, from multiple sources across the plant and/or enterprise
Applying advanced analytical calculations and business rules to contextualize and analyze this data
Configuring smart and thin client tools to distribute and visualize knowledge/ information to display critical operational metrics and integrate the user experience across different roles within the enterprise.
