I changed nothing for 30 days

When you’re the first SRE leader somewhere, the instinct is to arrive with a playbook and start rewiring in week one.

What that usually produces:

• Changes nobody asked for
• A team that goes quiet
• Two new problems replacing one old one
• A reputation you spend six months undoing

So the first month isn’t for changing anything.

What it’s actually for:

• Mapping the architecture as it really is, not as the diagram says
• Sitting in incident reviews without commenting
• Reading the dashboards nobody trusts and finding out why
• Asking every engineer: what breaks most often?
• Asking the harder one: what should I not change yet?

That second question is the valuable one. It finds the load-bearing duct tape — the thing that looks wrong and is holding everything up.

Changing systems you don’t understand isn’t leadership. It’s expensive guessing.

The question isn’t “what do I fix first?”

The question is “what do I need to understand before I’m allowed to fix anything?”

What did your first 30 days somewhere new actually look like?
