Identification & Detection

The lifecycle begins when an incident is detected through user reports, monitoring alerts, or third-party notifications. Critical at this stage is distinguishing between incidents (service disruptions) and service requests (standard requests).

Best Practices:

Implement proactive monitoring to detect issues before users report them
Use AIOps to correlate alerts and reduce noise
Train agents to quickly differentiate incidents from service requests

Incident Logging

Every incident must be logged immediately with complete and accurate information. This creates the foundation for the entire resolution process and future analysis.

Best Practices:

Use standardized templates to ensure consistent data capture
Capture user info, description, affected CI, timestamp, and initial assessment
Assign unique tracking IDs automatically for easy reference

Categorization

Proper categorization enables effective routing, reporting, and trend analysis. Use a hierarchical structure (e.g., Hardware > Laptop > Battery) for granular tracking.

Best Practices:

Maintain a clear, logical category structure aligned with your services
Regular training on proper categorization for all agents
Use AI to suggest categories based on ticket content

Prioritization

Priority determines the order of resolution. Use an impact/urgency matrix to assign priorities objectively, ensuring critical business issues are addressed first.

Best Practices:

Use a formal impact/urgency matrix for consistent prioritization
Align priority levels with SLA response and resolution times
Consider business criticality, not just technical severity

Initial Diagnosis

The service desk analyst investigates the issue using diagnostic scripts, knowledge base articles, and user information to identify potential solutions.

Best Practices:

Always search the knowledge base first for known errors and solutions
Use diagnostic scripts and troubleshooting guides for consistency
Gather complete information before escalating to minimize handoffs

Resolution & Recovery

Apply the identified solution to restore normal service operation. This may involve fixes, workarounds, or escalation to specialized teams for complex issues.

Best Practices:

Test the solution before confirming with the user
Document resolution steps clearly for future reference
Keep users informed throughout the resolution process

Incident Closure

Close incidents only after user confirmation. Update records with resolution details and closure codes. This is the perfect time to gather satisfaction feedback.

Best Practices:

Never close without user confirmation of resolution
Use accurate closure codes for trend analysis
Send satisfaction surveys to measure service quality

Performance Analysis

Your current metrics show signs of an understaffed service desk struggling with volume. Low FCR and rising backlog indicate knowledge gaps and potential burnout. Focus on knowledge management and consider automation to improve efficiency.
