Yo, real talk. I’ve made Plenty of mistakes in IT. One sticks with me because it wasn’t about not knowing it was about staying quiet when I needed to speak up.
At GM, we had a cross-team project rolling out OT network upgrades. I saw issues early: electrical mismatches, incorrect port configuration, things that could slow down or halt operations. I brought it up briefly in meetings, but I didn’t follow through. I didn’t document. I figured someone else would handle it.
My silence cost the company tens of thousands of dollars.
We had equipment delays, techs standing around waiting, and engineers forced into emergency fixes. All of it could’ve been avoided by clear communication and simple documentation. I had to own that because I caused the issue, I didn’t clearly communicate it.
I’m sharing this because many of you will soon step into roles in IT - Cybersecurity or tech support. Remember this clearly:
Clear communication isn’t optional. It’s your protection, your team’s protection, and your company’s protection.
Speak up when something doesn’t look right. Follow up even if you feel annoying. Document everything clearly as if you’ll need it to defend your choices later because you might.
This is why we emphasize communication here. This is why we check logs. This is why we document every step.
Now, your turn. What’s one mistake you made that taught you something valuable the hard way?
Let’s hear it!
