Phrases I have said as an IT admin, what happened next, and what I should have done. A PSA from someone who has paid the tuition.
"I'll just give them admin for a sec." What happened: that "sec" is now eighteen months and a promotion long. They are admin on a system that was decommissioned in 2023. The system still exists because they have admin on it. Better: time-bound elevation. If your IAM tool supports JIT access, use it. If not, write a 24-hour expiry script and call it a feature.
"It's a one-off, no need to document." What happened: it is now 2026. The one-off has been performed quarterly by three different people. Two have left. The institutional knowledge consists of a single Slack message that reads "you know the thing we do." Better: three-sentence README. Future-you will weep with gratitude. Past-you will be forgiven nothing.
"I'll hardcode it temporarily." What happened: the value is now in seven scripts and a Lambda. The original engineer has left. The value has changed. Production has feelings. Better: env var or secrets manager. Four extra minutes upfront. Take the four minutes.
"They're leaving on good terms, no rush on offboarding." What happened: not bad terms, just neutral ones. They are also still in Slack, GitHub, and the AWS console six weeks later. The "good terms" is mutual because they have not yet noticed they still have access. Better: same SLA for every offboarding regardless of vibe. Vibe-based access policies are how incident reports get written.
"I'll just open a port real quick to test." What happened: the port is still open. The test was successful. So is everyone else's test. Better: temporary security group rule with an actual expiry. Or a tunnel. Anything but "I'll close it later."
"I'll fix it after the demo." What happened: the demo went well. The fix did not. The fix will not. The fix is now a load-bearing feature of the architecture and is referenced in the docs. Better: open the ticket before the demo ends. Put it on the sprint. Shame is the deadline.
What's yours? I'm collecting these so I can pretend I am not alone.
