Inside Food Business Operations | DeliDelights
Running out of an important product or ingredient is one of the more visible problems in a food business.
A restaurant discovers that a key ingredient is unavailable during service. A café cannot prepare one of its regular menu items. A retailer runs out of a product customers are asking for. A manufacturer or caterer discovers that a required material is insufficient for an upcoming order.
The immediate explanation often seems obvious:
We didn't have enough inventory.
And sometimes that is exactly what happened.
But operating a food business has made me increasingly interested in another possibility:
What if the stockout is not the problem itself, but the final result of something that happened earlier?
Understanding that difference matters because the appropriate solution depends on what actually caused the stockout.
The Obvious Solution: Keep More Stock
When something repeatedly runs out, one natural response is to increase inventory.
If we normally keep ten units, perhaps we should keep fifteen.
If we order once a week, perhaps we should order more each time.
That may solve the problem.
But in a food business, carrying more inventory has consequences.
More stock requires more working capital. It occupies storage space. Refrigerated or frozen products require appropriate capacity. Perishable ingredients introduce expiry and spoilage risks. Demand can change, leaving the business with products it no longer needs as quickly as expected.
So the objective cannot simply be:
Never run out of anything.
Neither should it be:
Keep inventory as low as possible.
The more useful objective is to maintain enough of the right inventory to support the business without unnecessarily increasing cost, working capital and wastage.
To do that, we first need to understand why stockouts happen.
A Stockout Can Begin With Demand
Suppose a restaurant normally uses ten units of an ingredient each day.
Purchasing and inventory decisions are naturally influenced by that pattern.
Then demand changes.
Perhaps it is payday weekend.
Perhaps a particular menu item suddenly becomes more popular.
Perhaps there is a promotion.
Perhaps a large group arrives unexpectedly.
Perhaps seasonality or an event changes customer behavior.
Inventory that would normally last four days may now last only two.
Nothing necessarily went wrong with the inventory count or purchasing process. The assumption about demand simply changed.
This raises an important question:
How quickly does a change in actual demand influence the next purchasing decision?
If purchasing continues to work from yesterday's assumptions while customers are already behaving differently today, a stockout can become increasingly likely.
Or It Can Begin With Inventory Information
Another possibility is that the business believes it has more stock than it actually does.
The system says 20 units.
The stockroom has 14.
The difference could have many causes.
Usage may not have been recorded correctly. There may have been wastage. A transfer may not have been captured. Physical counts may not have been updated. Portions or yields may differ from assumptions.
Whatever the reason, the purchasing decision is now being made using incorrect information.
The problem may eventually appear as:
“We ran out.”
But the earlier problem was:
“We thought we had more than we actually had.”
That is a very different problem to solve.
Sometimes We Simply Reorder Too Late
A business may know exactly how much inventory it has and still run out.
Consider an item with five days of remaining stock.
If the supplier normally delivers within two days, there appears to be enough time.
But what if nobody reviews the stock level until only one day's supply remains?
The inventory information was correct.
The supplier was capable of delivering.
Demand behaved normally.
The problem was decision timing.
This is where reorder points and replenishment processes become important.
It is not enough to know how much inventory remains.
The business also needs to know:
At what point does that inventory level require action?
And Sometimes the Business Did Everything Right
There is another scenario that many food businesses will recognize.
The business monitors inventory correctly.
It identifies the need to reorder.
Purchasing places the order on time.
Then the supplier says:
“Sorry, we're out of stock.”
Or:
“Delivery will be delayed.”
Now the problem has moved beyond the four walls of the business.
Supplier availability matters.
So does lead time.
A purchasing decision based on a normal two-day lead time may no longer work if the supplier suddenly needs five days.
A product that is normally readily available may temporarily become scarce because of importation issues, raw-material availability, production problems, transportation delays, seasonal demand or other supply constraints.
The business may have followed its normal process correctly.
What changed was an assumption elsewhere in the supply chain.
The Information May Already Exist
There is also a less obvious possibility.
Someone already knows that there may be a problem.
The kitchen knows consumption has increased.
The stockroom notices that inventory is falling faster than usual.
Purchasing knows the next order has not yet been placed.
The supplier has already warned someone that availability will be limited.
Management knows that a large booking or promotion is coming.
Each person may hold one part of the picture.
But has that information come together?
This connects directly with something we explored in the first two articles in this series.
The challenge is not always the absence of information.
Sometimes the challenge is whether the right information reaches the right person early enough to influence a decision.
The Same Stockout, Different Causes
Consider five businesses that all experience exactly the same visible problem:
An important item runs out on Friday.
The underlying causes could be completely different.
Business A: Demand unexpectedly increased.
Business B: The recorded inventory was inaccurate.
Business C: The reorder decision happened too late.
Business D: The supplier could not fulfill the order.
Business E: People had enough information to anticipate the problem, but the information did not reach the decision-maker in time.
All five businesses experienced a stockout.
But recommending that all five simply carry more inventory would overlook the real problem in four of them—and perhaps even in all five.
There May Be Other Causes Too
These examples are not intended to be a complete list.
Food businesses operate under very different circumstances.
Cash flow may affect when a business can purchase.
Minimum order quantities may influence how much can practically be ordered.
Storage or freezer capacity may limit how much stock can be carried.
A supplier's delivery schedule may restrict replenishment days.
Some ingredients may have short shelf lives.
Substitutes may be difficult to find.
One location may have excess stock while another location runs out.
And sometimes the business may deliberately accept occasional stockouts because carrying additional inventory would cost more than the lost sales.
That is why understanding the actual operating context matters.
Ask What Happened Before the Stockout
When an item runs out, instead of immediately asking:
“Why didn't we keep more inventory?”
it may be useful to reconstruct what happened.
What was the actual inventory before the stockout?
Was that quantity accurately recorded?
Was demand behaving normally?
When should the business have reordered?
When did it actually reorder?
What was the expected supplier lead time?
What was the actual lead time?
Was the item available from the supplier?
Did anyone know beforehand that something had changed?
If so, when did they know?
And when did that information reach the person who could act on it?
These questions begin to move the discussion away from the visible symptom and toward the underlying cause.
The Earlier We Know, the More Options We Have
This may be one of the most important aspects of the problem.
If we discover a stockout only when the shelf, refrigerator or freezer is empty, our options are limited.
But suppose we know three days earlier that current inventory will probably not last until the next delivery.
Now the business may have choices.
It may reorder earlier.
It may increase the quantity.
It may contact another supplier.
It may transfer inventory from another location.
It may adjust production.
It may use a substitute.
It may temporarily manage customer demand differently.
The information itself does not solve the problem.
It creates time to make a better decision.
And in operations, time can be extremely valuable.
Perhaps the Better Question Is Not “How Much Stock?”
Inventory management naturally involves deciding how much stock to keep.
But before increasing inventory, another question may deserve attention:
What caused us to run out—and when could we reasonably have known that it was going to happen?
That question connects inventory with demand, purchasing, suppliers, lead times and information flow.
It also recognizes that what appears to be an inventory problem may sometimes originate somewhere else entirely.
For those of us operating food businesses, understanding that distinction could be useful.
Because the goal is not simply to have more inventory.
The goal is to make better replenishment decisions with enough time to act.
