Problem ManagementActivities • Problem Control • Identify, classify and solve problems • Root cause identification • Provide work-around to the Service Desk • Error Control • Review and assess Known Error identified from Root Cause • Eliminate known errors using the Change management • Prevent incidents - trend analysis and place preventive measures
Service Desk & Problem Management Incidents vs Problems • Propose incidents • Incident Matching • Identify recurrences of solved problems • Report and identify new work-around • Identify trend
