ITIL roles and responsibilities

Day 7: ITIL Roles – Who Does What in This Drama?

🎥 SCENE: War Room – “Outage on the Floor”

📺 A critical outage hits the live environment.
A red alert pops on the NOC dashboard.
🎧 Narrator:

“This isn’t just about technology anymore…
It’s about roles, responsibility, and reputation.
Every second counts.
And every person matters.”

Zoom into:

  • 👩‍💻 Service Desk Agent typing furiously
  • 👨‍🔧 Resolver Group juggling 3 incidents
  • 👨‍⚖️ Approver reviewing a high-risk change
  • 👨‍🔬 Problem Manager connecting the dots
  • 👩‍🏫 CAB whispering: “Should we allow this change?”

🎯 Each role in ITIL has a purpose — let’s explore them.


🎭 Main ITIL Roles & What They Do

RoleDescription
User 👩‍💼Raises tickets, reports issues
Service Desk Agent ☎️First responder – logs, assigns, updates
Resolver Group (L2/L3) 🔧Solves the issue, adds solution notes
Incident Manager 🚨Handles major incidents, ensures SLAs
Problem Manager 🧠Investigates root causes, manages workarounds
Change Manager 🔄Reviews and controls all changes
ApproverGives permission to implement risky changes
CAB (Change Advisory Board) 🧑‍⚖️Group that evaluates high-impact changes
Configuration Manager 📦Maintains CMDB and CI accuracy

Process Owner 📚Defines and improves ITIL processes

🧪 Example: Live Email Issue

Let’s say:

  • User can’t access company email
  • SLA = 1 Hour

🔥 Who does what?

  1. User raises ticket – “Help! Email down!”
  2. Agent logs it, tags urgency
  3. Resolver investigates → finds server issue
  4. Incident Manager declares major incident
  5. Change Manager initiates emergency patch
  6. Approver green-lights it
  7. CAB reviews for long-term changes
  8. Problem Manager finds recurring pattern
  9. Configuration Manager updates CI link
  10. Service Owner tracks business impact

🎯 Like a well-run operation theatre — everyone has a critical role!


💡 Real Life Tip

Even in small teams, these roles may overlap.
A single person could be both resolver and incident manager.

But the mindset matters — not just “who does it” but how it’s done.
