The first time you see every device in a building, it's a shock. Hundreds of them. Some you didn't know existed. A long list of problems, and a team that's already busy.
The instinct is to sort the list by how scary each problem sounds. Resist it. A frightening technical label on a device that can't reach anything important is a distraction. A dull-sounding problem on the gate reader that controls your yard can cost you a day of shipping.
Instead, ask three questions about every device.
What can it reach? A camera that only talks to its own recorder is a small problem. A camera on the same network as your warehouse management system is a big one, because it's a stepping stone to the system that runs your orders.
What breaks if it fails? Follow the device to the work it supports. If the gate reader goes down, can trucks get in? If the RFID reader at dock four goes down, can you receive inventory? If the temperature sensor in cold storage goes quiet, would anyone notice before the product spoils? The closer a device sits to safety, shipping, inventory, or temperature, the higher it goes on the list.
Can we safely change it today? Some fixes take five minutes and nobody notices, like changing a factory password during a quiet hour. Others need the vendor, a part, and a weekend shutdown. A dangerous device with an easy, safe fix goes straight to the top. A lot of risk can disappear in the first week.
For the problems you can't fix yet, don't just leave them sitting there. Fence them in. If an old conveyor controller can't be updated until the next shutdown, limit it so it can only talk to the one system it needs. That buys you time without leaving the door open.
This is what we mean by Prove. You end up with a short, ranked plan, built on evidence from your own building, that says what to fix first and why. A list tells you what's wrong. A plan tells you what to do on Monday.
And it gives you something every operations leader needs: a reason your team can defend. When someone asks why you fixed the gate reader before the lobby camera, you can show them.
