The Spares Shelf

Your business doesn't need a spares room. It needs a shelf.

What's on the shelf

Start embarrassingly small. A keyboard and a mouse - because when one dies at 8:55 on invoice day, the difference between "grab the spare" and "drive to Officeworks" is your whole morning. A phone charger and a laptop charger. The cable everyone always loses - HDMI, USB-C, whatever your setup eats. Total outlay: less than a round of Friday drinks.

Then the serious item: a spare laptop. Not a new one - the machine you just replaced, wiped, updated, signed into nothing, with a note taped to the lid saying what it's for. When the main machine dies, gets stolen or goes swimming, you're working again in the time it takes to log in to your cloud services. That assumes, of course, that your business actually lives in cloud services and tested backups rather than on one hard drive - the spare laptop is the second half of a strategy, not the whole of one.

And a UPS - an uninterruptible power supply, which is a grand name for a battery in a box. Does your business actually need a UPS? If your internet router, your network storage or your EFTPOS base station would hurt you by losing power mid-afternoon, yes. A small UPS rides through the blinks and brownouts that crash equipment, and gives the bigger gear time to shut down cleanly in a real outage instead of corrupting itself on the way out. For a few hundred dollars it's the cheapest insurance on this list - and unlike most insurance, it works dozens of times a year without you noticing.

The arithmetic nobody runs

Here's the sum that makes the shelf obvious. Take your loaded hourly cost - yours, or your most senior person's. Multiply by the hours a dead piece of equipment costs you: the diagnosing, the driving, the buying, the setting up, the catching up afterwards. A dead laptop is rarely less than a day. A dead morning is the floor.

Now price the shelf: a few hundred dollars of small kit, a retired laptop you already own, a UPS. The shelf wins on its first use. Everything after that is profit. The reason businesses don't do it isn't cost - it's that spares feel like waste right up until the moment they're the only thing that isn't.

The mining companies understood this in their bones, because their downtime had a published price per minute. Your downtime has a price too; nobody's published it, so it feels like zero. It isn't zero. You just haven't been invoiced for it in a single line item - it arrives as a quiet Tuesday you'll never get back and a customer who rang someone else.

Two rules that keep the shelf honest

First: the shelf is for spares, not storage. The moment it fills with dead equipment "to sort out later", you own a museum, not a contingency. The spare laptop earns its place only if it's charged, updated and actually signs in - which means picking it up once a quarter and checking. An untested spare is a hope with a power button.

Second: write the shelf into your run book - what's on it, where it is, and what the swap steps are - so the recovery works on the day you're not in the building. Resilience that lives only in your head is a single point of failure wearing a high-vis vest.

None of this is sophisticated. That's rather the point. The security industry will happily sell your business another dashboard, but nobody gets commission on a $30 keyboard - so this advice arrives from a different direction: from every operations crew that ever kept something important running. What would a dead laptop cost you tomorrow morning, and what's sitting on your shelf?
