Change Review

4 min read
On this page

In this lesson, you will learn:

  • The three change types
  • How risk is worked out
  • How approvals and CAB work
  • Where to go back if you’re unsure

🔁 Quick look back: Last time: Incident and Problem Review. You learned the key incident and problem facts, through Sam’s VPN story.

1 “Standard, normal, emergency… which is which?”

Change is 30 of the 118 practice test questions.

  • There are three types.
  • Risk has two parts.
  • Approval rules depend on both.

🎯 The problem: Change facts link together. If one is fuzzy, others get fuzzy too.

👉 The fix: review them through SNWR’s three real changes.

2 SNWR’s three changes

SNWR's three changes as a review. Standard: Restart SNWR mail service, from a pre-approved template, no CAB. Normal: CHG0030045 Replace VPN gateway certificate, risk from the risk assessment and risk conditions, approved by the group manager then CAB, scheduled in the Sunday maintenance window. Emergency: CHG0030046 Fail over SNWR Email to snwr-mail-02, approved by the emergency CAB during the major incident.
Figure 1. Three types, three paths.

3 Key facts to know

Topic Remember
Normal states New, Assess, Authorize, Scheduled, Implement, Review, Closed
Risk Risk assessment answers plus risk conditions
Blackout vs window A blackout blocks changes; a maintenance window welcomes them
Conflicts Blackout, outside window, same CI at the same time
Approval policy Type and risk pick the approvers
CAB A CAB definition builds meetings and agendas; run them in CAB Workbench
Close codes Successful, Successful with issues, Unsuccessful

💡 Good to know: Standard changes are pre-approved because the template was approved once, through a proposal.

4 Quick recap

  • Standard: pre-approved template
  • Normal: risk, approvals, maybe CAB
  • Emergency: emergency CAB, linked to a major incident
  • Risk = assessment + conditions
  • Type and risk pick approvers
