Critical Materials: Keep Work Moving

Imagine an ordinary morning. There is an order in the calendar, the client has confirmed the time, and the team already knows what to do. You open the cupboard or storage shelf - and one small item is missing. Not the main product, not expensive equipment, but adhesive tape, the right box size, a cartridge, an attachment, packaging, or a form. Without it, the work cannot start or cannot be completed properly.

The most frustrating part is not the purchase itself. If you had found out earlier, you could have ordered it calmly, replaced the item, or honestly adjusted the promise. But now you have to call, search, travel, message the client, and explain why a small thing suddenly became a big problem. A broken process knows how to turn a paper clip into the head of crisis management.

You do not need to turn your business into a warehouse with endless spreadsheets right away. Start with a simpler question: what exactly would stop a specific order or an ordinary working day if it were not at hand?

A critical item is a material, product, or consumable without which you cannot complete an order, work safely, or switch to an acceptable option. It is not necessarily the most expensive purchase, and it does not necessarily take up much space.

The most damaging things are often small items people remember only while working. The last roll of packaging, a set of gloves, or a part for equipment can easily be treated as something that “must be somewhere else.”

Look at one of your recurring processes from start to finish. If you bake desserts, mentally follow the path from a confirmed order to handover: ingredients, box, cake board, sticker, delivery method. If you provide a service, check not only the material for the work itself, but also what makes it possible: consumables, clean tools, media, documents, a charged device.

Separate critical from familiar

Ask: can you deliver the result without this item, replace it without a worse result, and would its absence create a safety risk? If the answer is “no” even once, put the item under separate control.

A hypothetical example: Olena makes gift sets. She carefully tracks expensive products because they determine the price of a set. Yet an order stopped because there was no box filler: without it, fragile items could not be shipped safely. The filler was not the central product, but it was a critical item. After that, Olena did not begin tracking every ribbon. She added only the things without which a set could not be assembled and shipped to a short list.

This selection also protects your money. You do not need to buy lots of everything “just in case.” Excess can also become a problem: it can sit unused, spoil, become outdated, or simply tie up money needed elsewhere. Your goal is to see stopping points, not fill every shelf.

A shared list is one clear spreadsheet or note that both the person who notices a shortage and the person who can order a refill can access. In our experience, such a simple list is more useful than a complex system that nobody uses.

Do not start with a catalogue of everything in the business. Create a separate list of critical items for one service, one order type, or one working day. Next to each item, write the current quantity, storage location, responsible person, check point, primary seller, and backup option. If you work alone, you will be the responsible person - but it is still important to write it down so the decision does not live only in your memory between a call and a delivery.

Do not try to guess the perfect format. For some people it will be a spreadsheet on a phone, for others a sheet in a shared workspace, and for others a short note near the place where the material is taken. What matters is not how much it resembles software for a large warehouse. What matters is whether a person can see without guessing what is missing, who needs to act, and where to get it.

Set the point for replenishment

A reorder point is a predetermined quantity or moment when you do not wait until everything is gone, but start replenishing. It is set not by someone else’s example, but by how often the material is used, how quickly it can be obtained, whether delays happen, and whether there is a suitable replacement. A broken machine is noticeable, but the last roll is easy to miss. So tie the check not to “remembering,” but to an event: closing the day, a new order, or receiving a delivery. Then it becomes part of the work rather than a task heroically moved to tomorrow.

A hypothetical example: Andrii runs a small repair workshop. He did not record every screw and wipe, because that would take his whole evening and his patience. Instead, for the few jobs he performs most often, he marked the materials without which a repair cannot be completed correctly. When a new order appears, Andrii checks those items specifically against it. This way, he sees the risk before the client brings in the item, not at the moment when everything has already been taken apart.

If you later have more data and recurring purchases, you can turn simple tracking into regular monitoring of indicators and decisions together with analytics. But first, it is more useful to learn to answer the basic question: do we have enough of what would stop today’s work without it?

A backup supplier is not necessarily a second company from which you constantly buy the same thing. It is a tested backup route: a contact, shop, manufacturer, or another way to get a critical item if the primary option is unavailable.

Having one supplier does not by itself mean you are doing something wrong. And a backup option does not guarantee that every disruption will disappear. Still, for items your ability to keep a promise depends on, it is useful not to search for an alternative for the first time in a panic. Check in advance whether the backup contact sells the item you need, whether its terms work for you, and what exactly you can take instead of the usual option.

An acceptable replacement is a material option you have decided in advance is suitable in terms of quality, safety, and the client’s expectations. If there is no such replacement, write that in your list. It is a more honest answer than trying at the last minute to present any similar product as equivalent.

Think beyond the name of the backup contact. Write down exactly what you can get from them, which option is acceptable, and what requires the client’s approval. For branded packaging, a replacement may be unacceptable. For an ordinary consumable, it may not change the result. The decisions differ, so it is not worth using one template for all purchases.

If you notice the shortage risk early, it is usually easier to agree on an option with the client than to explain a postponement at the last minute. You can offer another material, another time, or another configuration before the situation becomes an emergency. What matters here is not a polished explanation, but honesty and choice: the client sees that you are managing the situation, rather than learning about it at the same time as they do.

When a material runs out, it is easy to make a broad conclusion: “we need to buy more.” More often than not, this is not an answer, but a way to quickly silence anxiety. First, it is worth understanding why you found out too late.

Perhaps the item was available, but nobody knew the real quantity. Then the problem is that the list is not updated or is not kept where people work. Perhaps the quantity was visible, but there was no moment when an order had to be placed. Then you should change the reorder point or the check event. Perhaps the primary seller could not ship the product. Then you need not simply find a new seller, but determine whether there is an acceptable replacement and how you will act in that scenario.

Another situation is that the material was used for something other than what you had planned. For example, an urgent order appeared, an employee took the last reserve for another job, or part of the product turned out to be unusable. In that case, it is useful to record not only the quantity, but also why it changed. Not to look for someone to blame. To see a pattern next time rather than repeat the same surprise under a new name.

Do not turn this into an interrogation of the team. The question should be simple: where exactly did the process stop giving you a signal? Once you find the answer, the action also becomes specific: move the check closer to the order, add a responsible person, agree on a replacement, or record a backup contact.

The first review is not a major check of the whole business, but a careful walk through one route: from the promise to the client to the finished result. Choose a familiar service or a typical day, write down the sequence, and stop at the things without which the next step is impossible. Keep only critical items on the short list. For each one, add a responsible person, check event, reorder point, primary purchasing method, backup contact, and an acceptable replacement if one exists. Also ask whether you can quickly buy or replace the item without a worse result and an unpleasant situation for the client. This is not bureaucracy, but a way not to rely on memory when there is a lot to do.

Do not wait until the list is perfect. After the next purchase, completed order, or awkward situation, return to it and clarify what was missing. As a rule, such a list grows not from a desire to control everything, but from specific places where your work can truly stop.

The first step is simple: today, choose one upcoming order and name one small thing without which you will not be able to deliver it as promised.
