Lessons of 2020 for manufacturers
Flexibility, supplier diversification, contactless logistics — the main lessons of 2020 for food industry manufacturers.
2020 was a stress test for the whole food industry. Supply disruptions, new sanitary requirements, unstable demand — all this tested manufacturers for flexibility. In this article we sum up the main lessons of the year from the standpoint of an equipment manufacturer who saw what happened on dozens of lines.
Lesson one: flexibility matters more than scale
Before 2020, many plants optimised their lines for a single product and maximum throughput. The year revealed the weakness of this approach: when demand for one SKU fell, a narrowly specialised line stood idle because it could not quickly switch to another product.
Manufacturers whose lines allowed quick changeover between several SKUs weathered demand swings more easily. Flexibility came to be valued above peak throughput. On our new projects we increasingly build in a multi-product layout — a line that serves several recipes with minimal changeover time.
Lesson two: one supplier is a risk
The logistics disruptions of 2020 hit plants that depended on a single source of components. A closed border or a stopped supplier plant stopped a line for weeks.
The conclusion is simple: critical components must have at least two sources. This applies to belts, bearings, drives, electrical parts. A local supplier, even slightly more expensive, turned out to be strategically more beneficial than a cheap but single import channel.
Lesson three: sanitary requirements are forever
Contactless transport, distance between workstations, reinforced disinfection — 2020 made all this the norm. At first it was seen as a temporary reaction, but by the end of the year it became clear: hygiene standards will not roll back.
Plants that adapted their lines to the new requirements got a side bonus — many contactless logistics measures also sped up production. We wrote in more detail about adaptation in the article on food production safety.
Importantly, adaptation to sanitary requirements turned out to be not a one-off expense but an investment with a lasting effect. Contactless transfer, a well-thought-out workstation layout, sanitiser-resistant materials — all this stays in the line’s design and works every day, regardless of the epidemic situation. Plants that treated this as a modernisation rather than a temporary measure got a line ready for any future sanitary requirements.
What changed in demand for equipment
These lessons were reflected in what customers ask of an equipment manufacturer. If price and peak throughput were previously the key criteria, then after 2020 flexibility, repairability and independence from a single source of components came to the fore. Below is how the priorities changed.
| Trend | Before 2020 | After 2020 |
|---|---|---|
| Multi-product lines | niche request | mass request |
| Contactless transfer | optional | standard requirement |
| Local equipment | cost saving | resilience strategy |
| Critical spares stock | minimal | extended |
| Accounting automation | ”sometime later” | priority |
Engineer’s tip. If you are planning a new line after 2020, build in flexibility at the drawing stage, not “bolt it on” later. Converting a narrowly specialised line into a multi-product one costs many times more than designing for several SKUs from the start. It is the cheapest investment in resilience.
Lesson four: accounting automation stopped waiting
When a plant runs steadily, a lack of accurate productivity data is not critical. But in an unstable year decisions must be made fast, and that requires data. Plants without automatic accounting made decisions blind — not knowing the real throughput of each section or the true cost of a shift.
2020 moved accounting automation from the “sometime later” category into the priorities. Basic automation — sensors, product counters, simple visualisation — pays off not so much through throughput as through the quality of management decisions. A plant that sees the figures in real time spots a bottleneck faster and plans raw material purchasing more precisely.
Lesson five: staff are part of resilience
A separate lesson of the year was the line’s dependence on specific people. When a key mechanic or an experienced operator dropped out through illness or quarantine, it turned out their knowledge was recorded nowhere. A line run by one irreplaceable person is as vulnerable as a line with a single supplier.
The conclusion is practical: critical procedures — line start-up, emergency stop, typical fault clearance — must be described in written instructions, not kept “in the head” of one worker. Plants that had a trained reserve and documented procedures weathered staffing disruptions without stopping production.
Conclusion
The main lesson of 2020 for a manufacturer is that resilience matters more than maximum. A flexible line, two sources of components, a stock of critical spares and basic accounting give a plant the ability to survive a shock without stopping. We carry these conclusions into our own projects and build resilience into the design. If you are planning a new line or an upgrade taking these lessons into account, get in touch — we will factor them into the project. More industry reviews — in articles tagged trends.
