The Change Schedule

4 min read
On this page

In this lesson, you will learn:

  • What the change schedule is
  • What it shows
  • How Mei uses it before CAB
  • How it helps the Service Desk

πŸ” Quick look back: Last time: Conflict Detection. You learned how conflict detection finds clashes with blackouts, windows and other changes.

1 “What’s changing this weekend?”

Friday afternoon, Daniel asks a simple question.

  • “What’s changing this weekend? My agents need to know.”
  • Mei has to open 14 changes one by one to answer.
  • She misses one, and the desk is surprised on Monday.

🎯 The problem: A list of changes doesn’t show how they fit together in time.

πŸ‘‰ The fix: look at changes on a calendar: the change schedule.

2 What the change schedule shows

Key term: Change schedule

A calendar view of planned changes, with maintenance windows and blackouts shown too.

The change schedule for next week. Sunday 02:00 to 06:00 maintenance window: CHG0030045 Replace VPN gateway certificate, and CHG0030051 Update VPN software, both on snwr-vpn-gw-01, shown overlapping. Tuesday: CHG0030060 Add Wi-Fi access point, London. Last week of the quarter shaded as the quarter-end freeze.
Figure 1. Clashes jump out on a calendar.

3 How SNWR uses it

Who Uses the change schedule to…
Mei Spot clashes before Tuesday’s CAB
Daniel Tell agents what’s changing this weekend
Change owners Pick a free slot in a maintenance window

πŸ’‘ Good to know: The same schedule is available in the workspace, so agents can check it when calls come in after a change.

⭐ Remember: A list shows changes. A calendar shows how they fit together.

4 Quick recap

  • The change schedule is a calendar of planned changes
  • It shows maintenance windows and blackouts too
  • Clashes on the same CI are easy to spot
  • Mei uses it before every CAB
  • Daniel uses it to warn the Service Desk
