The document discusses using CICS (Customer Information Control System) transactions as a source of business events for event processing. CICS handles billions of transactions daily and is critical for many businesses. CICS can emit events at predefined points without changing existing applications, to provide insight into business processes and enable new extensions. This allows businesses to gain agility while avoiding risky changes to production code.
