Quick Navigation
I’ve been managing IT changes for over a decade, and the one thing that still makes me sweat is an urgent change. You know the situation: a critical production server is crashing, a security vulnerability just went public, or a payment gateway is down. Standard change review meetings? Forget about them. You need a process that’s fast but not reckless. That’s exactly what the urgent change process is.
Definition & Basics
The urgent change process (also called emergency change management) is a streamlined procedure to implement a high-priority modification that cannot wait for the normal change advisory board (CAB) cycle. Unlike a standard change, which follows scheduled reviews and testing windows, an urgent change trades some deliberation for speed — but it still keeps guardrails in place to prevent disaster.
Most frameworks like ITIL define an urgent change as one needed to resolve a major incident or prevent a severe business impact. The key is: it’s time-sensitive and the risk of not doing it is higher than doing it quickly.
When to Trigger an Urgent Change
Not every fire qualifies. Here’s when you should pull the urgent trigger:
- Service outage: A critical application is down and a fix is ready, but the next standard window is 12 hours away. No way can we wait.
- Security patch: Zero-day exploit in the wild. Every hour increases risk of breach. I’ve had to push a kernel patch at 2 AM — scary, but necessary.
- Regulatory deadline: A compliance mandate requires immediate configuration change to avoid fines.
- Customer impact: A bug is causing incorrect billing. Revenue loss and angry customers demand quick resolution.
But here’s a nuance I’ve learned the hard way: just because someone shouts “urgent” doesn’t mean it is. I once had a manager insist on an urgent change to update a report that looked ugly. We pushed it, and it broke a downstream system. Not worth it.
Step-by-Step Urgent Change Process
The exact steps vary by organization, but after implementing dozens of them, I’ve found this sequence works best:
- Identification & logging: Someone (usually the incident manager or a tech lead) identifies the need and logs an urgent change request. It must have a clear reason why it can’t wait.
- Initial assessment (15 minutes max): A small group — typically the change manager, the technical lead, and a risk representative — assess the impact, scope, and rollback plan. I always ask: “What’s the worst that can happen if we do this? And what if we don’t?”
- Emergency CAB (eCAB) approval: This isn’t a full 50-person board. You grab the essential decision-makers via phone, chat, or a quick meeting. Documentation can happen retroactively. In my company, we use a dedicated Slack channel with a bot that logs approvals.
- Implementation with guardrails: The change is executed, but with constraints: ideally during a predefined maintenance window (even for urgent changes, avoid peak hours if possible), with a timebox (e.g., must finish within 2 hours), and a clear rollback script ready.
- Verification: After implementation, monitor for at least 30 minutes. I’ve seen changes that looked okay but caused memory leaks an hour later. Don’t walk away.
- Post-implementation review (PIR) within 48 hours: This is where you learn. Was it truly urgent? Could we have prevented it? Did we skip any testing that we shouldn’t have? I always write down what went wrong.
| Step | Time Target | Key Question |
|---|---|---|
| Logging | Within 5 min of detection | Why is this urgent? |
| Initial assessment | 15 min | What’s the rollback plan? |
| eCAB approval | 10 min (async possible) | Who needs to confirm? |
| Implementation | As fast as safe (timeboxed) | Are we breaking SLA? |
| Verification | 30 min post-implementation | Are all services healthy? |
| PIR | Within 48 hours | What could we have done differently? |
Common Pitfalls & How to Avoid Them
I’ve made almost every mistake in the book. Here are the top three:
1. Skipping Rollback Planning
You’re in a hurry, so you skip writing the backout steps. Big mistake. I once had a colleague push a database patch without testing rollback. It corrupted some tables. Took us 6 hours to restore from backup. Now I enforce a rule: no implementation until a tested rollback script exists.
2. Overloading the eCAB
You want to be safe, so you invite everyone. But by the time you get 20 people on a call, you’ve wasted 30 minutes. Keep the emergency board tiny — three to five people with decision authority. You can always inform others later.
3. Treating All Urgent Changes as Equal
Not all urgent changes carry the same risk. A configuration change in a web server is different from a kernel upgrade. I categorize urgent changes into two tiers: “fire drill” (high risk, high impact) and “quick fix” (low risk, still time-sensitive). Fire drills require a full eCAB and a mandatory peer review. Quick fixes can be approved by the change manager alone. This prevents bottlenecks.
Real-World Example: The Midnight DB Patch
Let me walk you through a situation I handled last year. Our primary customer database (PostgreSQL) had a replication lag that kept growing. By 10 PM, it was 45 minutes behind. Our banking transactions were delayed, and the operations team was getting calls from the business.
We identified the root cause: a query plan change due to an auto-vacuum issue. The fix was to tweak a database parameter. Standard change would have waited for the next maintenance window (7 AM). We couldn’t wait — customers would be furious by morning.
I logged the urgent change, called my emergency CAB (two DBAs, the app lead, and myself). We assessed: risk was medium (parameter change is reversible), impact of not doing it was high (continued transaction delays). Approved in 8 minutes. Implementation took 3 minutes. We monitored for an hour — replication caught up. PIR the next day revealed that the auto-vacuum tuning had been misconfigured during a previous standard change. We updated our standard change checklist to include vacuum settings.
The lesson? Even urgent changes can reveal process improvements. Don’t just fix the symptom; fix the system.
