Secure your IT changes before they go wrong
An update, a migration, a change of provider — every IT change carries a risk that improvisation doesn't manage. Here's the method, and how Alerion tools it.
Signs of a change process that isn't secured
- A change has already had unexpected consequences on another system.
- No one knows precisely who has to approve a change before it goes to production.
- There is no rollback plan written down before acting.
Securing a change isn't about a sophisticated tool — it's about discipline: knowing what you're impacting, who decides, and how to roll back if needed.
The method: four questions before any IT change
What depends on the component I'm changing?
List the systems, integrations and business processes that rely on it — not just the obvious technical links.
Who has to approve this change?
A low-risk change and a change touching a critical system don't call for the same level of validation — define the threshold before you need it.
What's the rollback plan?
Write it before acting, not after the incident. A rollback plan improvised mid-outage is often the one that fails.
Who needs to be informed, and when?
The stakeholders affected — business teams, providers, internal customers — need to know a change is planned before it has already happened.
How Alerion tools this method
Three capabilities that replace improvisation with a verifiable trail, from the first draft to execution.
What do I risk breaking if I change this?
Alerion's impact analysis simulates the consequences of a change from the real dependency graph, before any action is taken.
See change impact analysis in detail →Who has to approve this sensitive action?
Sensitive changes (data deletion, rollback, suspension) go through an explicit human approval before execution — via a signed link, not a checkbox.
How do I document what changed?
Every change generates its own RFC record and, once executed, a Markdown export ready to archive or share.
