A Practical Visibility Checklist Before You Build a Control Tower
Two years into the pandemic, "supply chain visibility" stopped being a slide and became a survival skill. Procurement teams that once tracked orders in a quiet spreadsheet were suddenly fielding daily questions about where a container was, why a part was three weeks late, and whether a backup supplier could fill the gap. Many organizations responded by shopping for a control tower — a dashboard that promises a single, live view of everything moving toward them. That instinct is sound, but a control tower is only as good as the data feeding it. Buy one before your basics are in order and you get a very expensive screen showing you bad numbers in real time.
Visibility is not a product. It is the cumulative result of clean master data, agreed-upon definitions, and suppliers who actually tell you what is happening. Before you spend a dollar on tooling, walk the checklist below with your own purchase orders open in front of you. It is meant to be done this week, by the people who place and chase orders, not by a steering committee three months from now.
Run this checklist on your own orders
Pick your ten most critical SKUs. Not the easy ones — the items that stop a project or a clinic if they do not arrive. Everything below applies to these first. If you cannot see them clearly, the long tail is hopeless.
Find the promised date and the confirmed date for each. A requested delivery date is a wish; a supplier-confirmed date is a commitment. If your system only holds one of these, you do not have a baseline to measure slippage against.
Trace one order end to end. From requisition to PO to shipment to receipt. Note every place the status lives in a different system or somebody's inbox. Each handoff is a blind spot a control tower cannot fix on its own.
Check whether "shipped" means the same thing to everyone. Ask your supplier, your freight forwarder, and your warehouse what triggers that status. Mismatched definitions are the quiet reason dashboards lie.
Count how you learn about a delay. Does the supplier tell you, or do you find out when the dock is empty? If it is the latter for even three of your ten, your problem is communication, not software.
Identify a qualified second source for each critical SKU. Visibility without an alternative is just a clearer view of a problem you cannot act on. Note which items have no backup at all.
What the answers tell you
If most of your ten SKUs failed two or more items above, a control tower is premature. Fix the master data, nail down confirmed dates, and set the expectation with key suppliers that a delay must be reported within 24 hours — in writing, against the PO. These are low-cost moves that improve visibility immediately and make any future platform worth the money. With hybrid teams still the norm, written, system-of-record updates also matter more than ever; a status someone mentioned on a call has effectively disappeared.
If you passed comfortably, you are a good candidate for a control tower — and you now know exactly which feeds it must consolidate and which definitions it must enforce. Either way, you have spent an afternoon, not a quarter, learning where you actually stand.
