The document describes Independence Blue Cross's implementation of the Precertification Intake Encyclopedia (PIE) using Pega software. Key goals of the PIE project were to create a flexible system that could adapt to changing business needs, give business owners control over routine maintenance, and leverage existing data. Pega was chosen for its flexibility, business rule configuration, self-documentation, and ability to interface with IBC systems. The implementation followed Pega's SmartBPM methodology and focused on building reusability. Metrics showed high levels of reusability and minimal IT involvement after implementation.
