The Empty Square

Businesses are remarkably good at finding unused capacity. They are less good at recognising what it is for.

Give an efficiency consultant a sliding puzzle and you can imagine the first recommendation: there is room for another tile.

The observation is correct. The recommendation is disastrous.

A sliding puzzle works because one square is empty. Fill it and the board becomes wonderfully complete, admirably tidy and entirely useless. Every individual part is present. The system has lost the ability to move.

Something similar can happen in a business. The diary fills. The production schedule tightens. Every employee has a task, every machine has an order and every remaining hour has acquired a promise. From a distance, this looks like success.

Then a customer changes something.

The trouble with an arrangement that works perfectly is that it may require a perfect day. Most businesses have to make their money on the other sort.

The flattering business of being busy

Ask a business owner how things are going and “Absolutely snowed under” often arrives with the peculiar satisfaction of a complaint intended to impress.

It communicates several attractive things at once. Customers want us. Our time is valuable. The market has noticed. We are so successful that success has become inconvenient.

“We have a little room in the schedule” lacks the same social sparkle, even if the business saying it earns more money and gets home before dinner.

Research by Silvia Bellezza, Neeru Paharia and Anat Keinan helps explain the appeal. Their studies found that busyness could suggest competence, ambition and demand for a person’s time, thereby signalling status. They also found cultural differences: admiration for a crowded diary is not a universal human instinct. Their research concerns perceptions of people, rather than evidence that busier companies perform better.

But the temptation to confuse the two is easy to understand. The owner experiences a full diary as reassurance. The customer experiences it as the reason nobody has answered their email.

The same evidence is being interpreted by two people with rather different interests.

The curious value of nothing happening

Spare capacity has a public-relations problem. Its cost can be photographed. Its benefits often cannot.

An idle machine is visible. A delivery that would have been late is hypothetical. A free hour looks like lost revenue. The argument that never happened because someone had time to correct a mistake leaves no record in the accounts.

Consider an ordinary spare tyre. On almost every journey it contributes weight, occupies space and does nothing useful that an observer could point to. Assess it solely by its average daily activity and removing it looks sensible.

Its purpose, of course, lies in a particular kind of day.

Businesses can make the same mistake with time. They inspect the recovery allowance on a quiet Wednesday and conclude that it was unnecessary. A quiet Wednesday is weak evidence about what the business needs when a supplier misses a delivery.

This creates a bias in what gets defended. The cost of keeping some room has an owner and an invoice. The cost of removing it may arrive later, spread across overtime, rushed decisions, disappointed customers and one exhausted founder.

Averages do not keep appointments

Imagine a workshop capable of completing ten ordinary jobs a day. Booking ten jobs each day has an appealing neatness. Demand equals capacity. There is nothing left over to worry an accountant.

Unfortunately, “ordinary” describes an average. It does not oblige individual jobs to behave.

One takes longer. Another arrives without the correct information. Two customers need help simultaneously. A colleague is absent. The schedule has been designed around a day in which events politely take turns.

Queueing theory describes the consequence. When arrivals or processing times vary, waiting can increase sharply as utilisation approaches capacity. There is progressively less room to recover from a delay. In an INSEAD and Wharton study of engineering change orders, scarce capacity combined with processing variability created congestion; much of the elapsed time went into waiting for work to happen.

There is no magic utilisation figure that fits every company. Predictable production and irregular custom work need different arrangements. The useful question is whether the schedule can absorb the variation the business actually encounters.

A modest delay should remain a modest delay. With every available hour already promised, it can become the first instalment of a much larger problem.

Efficiency can become someone else’s inconvenience

Remove the allowance for things going wrong and somebody may still have to provide it.

The customer provides it by waiting. The employee provides it by staying late. Another customer provides it by having their order pushed back. The owner provides it on Sunday afternoon.

The business has improved the appearance of its schedule by relocating the untidiness.

For a hypothetical embroidery workshop, the difference might be a small allowance for corrections before dispatch. Most days, the work passes inspection and the allowance goes unused. On another day, a placement error needs correcting before uniforms leave for a restaurant opening.

A workshop with room can deal with the problem. One with a completely committed schedule must negotiate with reality: displace a job, extend the working day or explain why the opening date has become inconvenient.

The customer bought uniforms for an occasion. An internal measure showing excellent machine utilisation will offer limited consolation.

This is where operating decisions become marketing decisions. Reliability is part of what a customer learns to associate with a business. A company can spend money advertising dependability while arranging its production so that dependability requires a minor miracle.

The last order has neighbours

One more order can look irresistible when considered alone. The price exceeds the expected cost of doing the work. It contributes towards overheads. Refusing it feels like turning away money.

But it will enter a business already containing commitments.

Suppose an additional job would contribute €150 before exceptional costs. Squeezing it in requires €60 of overtime and €45 of express shipping on another order. The apparent gain is now €45, before any extra administration or compensation. These are illustrative figures, but the accounting problem is real enough: the attractive order and its unattractive consequences may be recorded in different places.

The salesperson sees a sale. Production sees a late evening. Customer service sees three anxious emails. Everyone has an accurate account of their part. Nobody necessarily sees the whole transaction.

This is particularly easy to overlook when the owner supplies the missing hours. The rescue may create no extra wage bill, which allows it to feel free. Yet it consumes the time in which the owner might have improved a process, quoted better work or noticed why so many orders now require rescuing.

A business can become highly skilled at selling its founder’s evenings without ever putting them on the price list.

Make availability look like a benefit

There is an awkward commercial twist. Customers may value a quick response while being suspicious of the availability that makes it possible.

An empty restaurant creates questions. So can a consultant who is immediately free. Is this person well organised, or has everyone else discovered something we have missed?

Customers are interpreting a signal with incomplete information. The business can help by explaining what its operating choices mean for them.

“We only have a few projects underway at a time, so the person responsible for your work remains available” is a different proposition from “We’re quiet this month.” A maintenance business that preserves capacity for a promised response window gives the unused time a recognisable purpose.

The explanation must be true. An invented waiting list merely adds fiction to the timetable. A credible promise describes something the business has actually organised itself to provide.

This offers a useful test for premium positioning. If the price is supposed to buy attention, where is that attention in the schedule? If it buys flexibility, what remains flexible after the orders have been accepted?

A premium promise needs an operating arrangement capable of supporting it. Elegant typography is considerably easier to arrange.

Give the empty square a job

None of this makes idle capacity automatically wise. A quiet business may urgently need more customers. An expensive machine standing unused for months is unlikely to be an undiscovered masterpiece of strategic restraint.

Useful spare capacity needs a purpose and a cost someone has considered.

Where does work repeatedly wait? Which deadlines matter most to customers? What kinds of surprise recur? Could a second trained person solve the problem more cheaply than additional equipment? The answers matter more than adopting a fashionable percentage of “slack”.

Location matters too. Extra room in packing cannot release an order waiting for artwork approval. Five available employees cannot replace the one person who knows how to resolve a particular fault. A business can look comfortably staffed while being dangerously dependent on a single crowded diary.

Follow several real orders through the process. Notice where they stop and what allows them to start again. The sensible intervention might be a recovery slot. It might be better preparation, clearer approval rules or teaching someone else a task the owner has never relinquished.

The empty square earns its keep by allowing something useful to move.

The difference between saying yes and being helpful

Small businesses often take pride in accommodating customers. This is a strength. It can also make an honest delivery date feel impolite.

“We can do Tuesday” is less immediately pleasing than “We’ll try for Friday.” It may be considerably more helpful.

A customer told the truth early can make arrangements. A customer reassured until the last possible moment acquires an emergency. The initial pleasantness has been financed with their future inconvenience.

The same applies to urgent work. Accepting it should involve a conscious decision about capacity, cost and existing promises. A rush fee only makes commercial sense if the business can provide a credible rush service. Charging extra for placing another customer’s delivery at risk is an arrangement unlikely to survive close inspection.

Clear choices allow a company to be accommodating without gambling on its schedule: a realistic standard date, a genuinely available urgent slot or a smaller first delivery where that would solve the customer’s problem.

There is considerable selling power in knowing exactly what can be promised. Confidence becomes more persuasive when it has somewhere to stand.

Measure the business after the rescue

The case for leaving room should eventually face numbers.

Try a limited change at a recurring bottleneck. Track completed work, on-time delivery, overtime, rework and contribution after exceptional costs. Include the owner’s additional hours. Otherwise the experiment risks measuring how successfully inconvenience has disappeared from the payroll.

Look at comparable work over a useful period. A quiet week with easy jobs proves little. The question is whether the allowance improves the economics of delivery under the conditions the company normally faces.

Some capacity can also be used to remove recurring problems. An hour spent clarifying artwork requirements may prevent repeated exchanges on future orders. Training a colleague can reduce dependence on the same overworked expert.

But keep the promises honest. An hour allocated simultaneously to production, emergencies and improvement has been sold three times. If urgent work always consumes the improvement allowance, the business has learned something about its real requirements.

Being permanently too busy to fix a recurring problem is one way of ensuring that it remains a recurring problem.

What the customer is really buying

A customer rarely buys a supplier’s maximum theoretical output. They buy a particular result at a particular time, with some reasonable expectation of what will happen if a detail changes.

That expectation gives spare capacity its commercial value. It can support the calm response, the correction without drama and the delivery that arrives when promised. These are small events from the supplier’s perspective. For the customer, they can be the evidence on which the next order is placed.

There is therefore something odd about selling reassurance while organising a company to operate permanently on the edge of its ability to cope. The brand promises composure. The timetable requires heroics.

A well-run business needs enough work to prosper and enough room to deal with the fact that work involves people. The balance will differ by business. It will also change as the business learns.

Before filling the last opening, it is worth returning to the sliding puzzle. The missing tile can look like a defect to someone counting the pieces. To someone trying to make them move, it is the most useful feature on the board.

Sometimes the cleverest thing a business can do with an empty square is leave it empty.
