Is there a difference between Diagnostics and Root Cause Analysis?
Diagnostics is more than Root Cause Analysis. It also includes Proactive Monitoring and Alerting (both on system and business process level) as well as Service Level Reporting (meaning all aspects of IT analytics). Root Cause Analysis provides the basis of data for Alerting and Service Level Reporting. Once Root Cause Analysis is setup, the next natural step of Diagnostics adoption is Proactive Monitoring and Alerting as well as Service Level Reporting. Proactive Monitoring refers both to Technical Monitoring and Business Process Monitoring.
