Real-time business activity monitoring for a Fortune 500 mortgage lender

Business activity monitoring (BAM) provides end-to-end visibility of business processes, enabling enterprises to make better-informed decisions and quickly address problem areas. A BAM framework is used for continuous event correlation, real-time alerts, and monitoring KPI statistics for business activities in real-time.
