Many operations meetings begin the same way: fifteen minutes of establishing what is actually true. Whose spreadsheet is current, which export is stale, whether the warehouse number or the ERP number is right. A control tower exists to remove those fifteen minutes.
What a control tower actually is
Strip the buzzword and a control tower is three commitments. First, a single data spine: every material movement — take-off, PO, GRN, issue — lands in one reconciled model, continuously, not at month-end. Second, exception-first presentation: the screen leads with what is wrong or aging, because averages do not need attention and outliers do. Third, drill-down to the document: every number can be traced to the PO line or delivery note behind it, or the view loses the only currency that matters — trust.
Why construction needs it
Construction supply chains are hostile to visibility: long lead times, site-level urgency that bypasses process, materials that change custody several times before installation. Because the data is messy, the industry has often accepted blindness as normal. But the mess is systematic, and systematic mess can be modelled.
The Control Tower I am building reconciles the take-off-to-issue chain and surfaces open exposure by project. The goal is simple: make interrogating the view faster than asking a person. That is the bar it has to clear before it is worth anyone's trust.
Build guidance
Start with the reconciliation, not the dashboard — a beautiful screen on unreconciled data is a liability with good typography. Ship the exception queues before the trend charts. And put a domain owner, not just a developer, in charge of the matching rules; the view encodes judgement, and the judgement has to come from someone who has lived the disputes.
