Technology
RFID is an extraordinarily useful technology. Attach a small UHF chip to a textile item and suddenly something that was previously almost anonymous can be identified individually, quickly and without direct line of sight. Hundreds of articles can be detected in seconds. Movements that once required manual counting can become visible almost automatically.
It is tempting, therefore, to think that installing RFID solves the linen-management problem. It doesn’t. RFID solves a much narrower problem: it gives the textile item an identity and allows us to observe it. What we do with that information is a different question.
Provider of evidence
Imagine a hotel that can now see that 3,842 bath towels are in circulation. That is certainly better than not knowing. But is 3,842 the right number? Is it too many? Too few? How many will the hotel need next month? How quickly are towels disappearing? Is slow laundry turnaround increasing the amount of stock required? Are some articles sitting unused? When should replacements be ordered?
The RFID chip cannot answer any of those questions. It provides the evidence from which answers can be built. This distinction matters because technology projects have a tendency to focus on what the technology can measure rather than on what the operation needs to improve.
Questions are answered
An RFID scanning portal can tell us that 600 sheets left the hotel this morning. Useful. But the management question might be whether 600 sheets should have left. The same scanner can identify that 580 came back the next day. Useful again. But now we need to understand whether the remaining 20 are delayed, missing, rejected, still at the laundry or have simply not been detected.
If the laundry consistently returns linen more slowly than expected, the important consequence may not be the missing detection at all. It may be that the hotel needs more inventory in circulation, and will be paying for it. This is where RFID tracking and textile management begin to separate. Tracking asks: where and when was this textile item seen? Management asks: What does what we are seeing mean, and what should we do about it?
Recognize its limitations
There is another reality worth acknowledging: RFID itself is not perfect. Chips fail, scans are missed, some existing linen may remain untagged when new stock enters the operation. Also, people do not always follow processes exactly as designed. Hotels and laundries are real operational environments, not laboratories.
A useful textile-management system cannot, and should not, depend on every textile item being read perfectly each time. It needs to understand incomplete information, recognize anomalies and still provide the hotel with a sufficiently reliable picture to make decisions. That is also why the success of an RFID project should not be measured by the number of tags installed or scanners deployed. Those are simply input mechanisms.
Recognize its capabilities
The more interesting measures come afterwards. Did the hotel reduce the amount of stock required to operate safely? Did laundry discrepancies become easier to resolve? Did housekeeping spend less time counting? Did purchasing become more predictable? Did losses decrease? Did the hotel identify shortages before they happened?
If the answer to those questions is no, then having an excellent RFID infrastructure is of limited consolation. RFID is an enabler, and a very powerful one. But hotels don’t create value by reading chips. They create value by making better decisions with the information those chips provide.
It’s where textile tracking ends and textile management begins.
