The instruction booklet that no one reads (and why)
Thursday morning, end of September. Outside the workshop in San Leucio the air has that first damp chill that rolls down from the hills of Caserta and makes you fancy another coffee. Inside, the smell is an unmistakable mix: warm PVA glue, freshly die-cut cardboard, wood dust, and the burnt dregs of espresso left on the edge of the workbench.
I was there with Berto. On the bench sat the first finished box from his new line of compact machines for artisan wire-drawing. A project he'd sunk two years into — callipers, broken boxes, sleepless nights and real savings. The box was beautiful: corrugated board with a matte finish, logo in bronze foil, a piece of industrial design that would have cut a fine figure at any European trade fair.
"Umberto, open this up," Berto says, handing me a box cutter. "Look how precisely the machine fits in. Not a millimetre of play."
I cut the tape, open the flaps. The machine's a gem of satin steel and brass. Then I move the bubble wrap aside and at the bottom find an A4 sheet folded in eight. Photocopy paper, 70 gsm, grey, printed with an inkjet printer that must have seen the 2000 Jubilee. Arial, size 6, lines crammed with no margin, one solid block of grey text that looked like the privacy notice for a derivatives fund.
I opened that sheet. The first line read, word for word: "Strict observance of the following operational requirements is recommended in order to avoid functional impairment of the motor unit or the forfeiture of the warranty provided by the manufacturer."
I looked at Berto. He wiped his grease-covered hands on a rag and looked at me with his head tilted, the way he does when he knows I'm about to say something he won't like.
"Berto," I said, "this machine costs four thousand euros. Why do its first words to the client sound like a court summons?"
He threw his arms out: "The engineer wrote that with the safety consultant. It's meant to protect me from claims if some clueless sort gets their hands inside without pulling the plug first."
That's the sickness right there. The idea that the instruction booklet is a necessary evil, a badly printed insurance policy shoved to the bottom of the box to dodge legal bother, rather than the final chapter of the buying experience.
It brought to mind the first time I pulled a Lumix G90 out of its box, bought from a shop near Piazza Municipio in Naples. A gorgeous camera body, solid, spot on. I open the Italian manual: three hundred pages of paper-thin stock. I turn to the chapter on manual focus and I'm faced with tangled clauses, nested subordinates, prose that reads like it was run through 1990s machine translation software from Japanese into German and then from German into bureaucratic Italian. To work out how to switch on focus peaking I had to spend twenty minutes on a forum written by a lad from Manchester. The official manual, paid for as part of the camera's price, was completely useless.
If you're selling a product — whether it's a five-thousand-euro machine or a box of artisan pasta needing gentle cooking — the instruction booklet isn't an afterthought. It's the voice you use to speak to your client at the one moment you're not there: when they try to make what they've already paid for actually work. Learning how to write an instruction manual that genuinely works isn't a stylistic exercise: it's part of the product itself, just as much as the material it's made from.
The booklet is the last text you write and the first thing the customer judges
Let's take a step back and knock down a common excuse. We spend tens of thousands of pounds on branding, art direction, photography shoots lit like a film set, and packaging with foil finishes that cost more than the raw materials inside. I went into how packaging speaks before you've even opened the box in the article on packaging that tells people who you are, but that story risks grinding to a halt right after the opening.
The moment the customer opens the box, the marketing stops. Use begins.
Right at that instant, something delicate happens in the psychology of the buyer: the shift from promise to verification. Five seconds earlier, the reader was a prospect being courted with perfect imagery and persuasive copy. Now they're a user with the product in hand, often tired, maybe in a rush, almost always without the technical know-how of whoever designed the thing.
If at that moment your product turns up accompanied by an incomprehensible text, badly formatted, written in awkward Italian or grotesque English translated on the cheap by some algorithm, the contract of trust snaps. Perceived value collapses. The implicit message that lands in the reader's brain is brutal: thanks for your money, it's your problem now.
A badly written instruction manual causes three immediate, entirely measurable losses:
Higher customer service costs.
The customer can't work out how to start the device, rings support, clogs up the phone lines, sends off irritated emails. Every support call is a slice of margin wiped out.
Returns and bad reviews.
A good chunk of returns in e-commerce and light engineering don't come from faulty products, but from products the customer couldn't get working within the first ten minutes. A one-star review on Google or Amazon rarely says "the metal's rubbish"; it almost always says "doesn't work", "far too complicated", "instructions were useless".
Damaged brand image.
If your external comms come across as elegant, warm and contemporary, while your user manual sounds like a 1984 court ruling from the Caserta Tribunal, you're demonstrating a glaring inconsistency at the core of your brand. You're showing that the care was just a commercial front.
The voice of the company can't change register depending on which department signs off the document. The human voice is the one true luxury we've got left, as I explained in the piece on the human voice as a strategic asset. And that voice has to stay clear, steady and respectful even when explaining how to clean a filter or replace a seal.
Why we write instructions like insurance contracts
The diagnosis for this mess is almost always the same: fear.
Modern instruction booklets aren't written to guide the user; they're written to defend the company in court. They're born in legal departments or the dustiest corner of the technical office, places where the absolute priority isn't being understood, but covering your back.
The result is that devastating linguistic phenomenon we might call defensive officialese.
Defensive officialese has precise structural traits:
Systematic use of the passive voice.
"The switch must be set to OFF by the operator" instead of "Switch it off". The passive voice depersonalises the action, hides who's doing what and creates an icy distance between writer and reader.
A pile-up of adverbs and abstract nouns.
"Cleaning should be carried out through the use of a lightly dampened cloth, avoiding the infiltration of liquid substances" instead of "Clean with a damp cloth. Don't let water get inside".
Over-technical definitions for everyday objects.
The plastic knob becomes "the analogue rotary adjustment device"; the power cable becomes "the primary voltage conductor".
A wall of shouted warnings before you've even been told what the product does.
You open the first page and find two sides covered in yellow triangles with exclamation marks telling you what happens if you swallow the cable, use the machine in a thunderstorm, or hand it to a three-year-old. Before you even know how to switch the thing on, the text has already told you you're handling a lethal device.
This structure conveys insecurity. When a company writes this way, it's not saying "here's how it's done"; it's saying "if you hurt yourself or break the thing, we told you so on page 4, footnote 12".
It's the same gap between a master craftsman standing beside you in the workshop, watching your hands and saying "turn the key gently until you feel a little click", and a court-appointed surveyor reading you a formal complaint.
The irony in all this is that clarity doesn't reduce legal protection: it increases it. A clear instruction, unambiguous and impossible to misread, protects both manufacturer and user far better than three pages of clauses written in archaic legalese that no judge will ever count as evidence of "transparent information to the consumer".
I'll admit something: I've fallen into this trap myself, from the other side of the table. Back in 2019, for a client hiring out portable lighting kits for micro-events between Naples and Portici, I wrote the assembly sheet for a folding softbox myself. I was in a rush, thought I knew that kit better than anyone, and instead of a numbered sequence I bashed out three dense paragraphs, convinced "it's obvious enough". The next day the client rang me back: an assistant of his had mounted the diffuser backwards during a wedding on the Portici seafront, the light had bounced straight into the guests' faces during the ring exchange, and the event photographer had to stop the ceremony for a good twenty minutes to remount everything. It wasn't the assistant's fault. It was mine. Since then I never write an instruction without first picturing someone reading it in a hurry, knackered, with the sunset light dropping.
The standards the serious industry uses that almost no SME knows about
The good news is we don't have to invent anything. Beyond the walls of our own lazy offices there are international disciplines and standards, codified for decades, that govern technical writing. The trouble is that in Italy these rules tend to stay locked inside the documentation departments of aerospace or pharmaceutical multinationals, never filtering down to SMEs or organised craft businesses.
Let's look at the two fundamental pillars every business owner or comms manager ought to know.
IEC/IEEE 82079-1: the cornerstone principle of user information
The international standard IEC/IEEE 82079-1:2019 (Preparation of information for use / instructions for use of products) sets out the general principles and detailed requirements for designing, preparing and presenting any user information for products ranging from complex industrial machinery to everyday consumer goods.
The founding principle of IEC/IEEE 82079-1 is revolutionary in its simplicity: user information isn't an accessory to the product; it's an integral part of the product itself. In the spirit of the standard, if the product works perfectly but the user information is lacking, ambiguous or inaccessible, the company is exposed to real risks — from needless support requests right through to legal action — exactly as if the fault lay in the physical product.
The standard sets out rigorous requirements covering:
- The target audience. The text must be pitched to the actual competence of the intended end user (expert, qualified technician, general consumer).
- How information is structured. Safety information must be woven into the flow of actions, not dumped all at once at the start.
- Visual readability. Minimum font size, colour contrast, layout and the combined use of text and images to cut cognitive load.
Simplified Technical English: how aviation cracked the problem
Back in the eighties, European airlines grouped under the AECMA association (now ASD) found themselves facing a critical problem: civil and military aircraft were built by international consortia, parts were assembled in different countries, and maintenance was carried out by technicians across the world whose mother tongue was almost never English. Misunderstandings in maintenance manuals were becoming a direct cause of serious safety risks.
The solution was ASD-STE100 (Simplified Technical English). It isn't an artificial language, but a controlled one built with strict rules to eliminate ambiguity.
Today STE comprises 53 grammar rules and a controlled dictionary of around 900 approved words. Every word has one permitted meaning and is assigned to a single part of speech.
The three golden rules of Simplified Technical English that anyone can apply right away are:
One word, one meaning.
If you decide to use the verb Close to mean shutting off a tap, you can't use the same verb to mean two parts coming together (Close the gap). For distance you'd use a different approved word. This wipes out any semantic uncertainty.
Short sentences, one action per sentence.
The standard sets a limit of 20 words for procedural sentences (25 for descriptive sections). Every sentence must contain a single operational command. No stacking two actions in the same sentence.
Only the active imperative verb.
No passive forms or nominalised verbs. You don't write "It is appropriate to carry out a check of the pressure"; you write "Check the pressure".
I remember, a year back, sat at a desk on City Road EC1V in London, trying to take my usual camera's manual and rewrite three pages of it following the logic of Simplified Technical English. The text shrank by 40% in volume. Reading time dropped by half. That performance anxiety you get when you need to set up an advanced configuration that half a day's work hangs on had simply vanished.
Clarity isn't a gift of nature; it's a technical choice, a matter of tidiness.
The IKEA case: when the words disappear and it works better
You can't talk about user instructions without mentioning the most famous, most studied and most discussed case study in the world: the IKEA booklets.
IKEA made a radical choice decades ago: strip written language out of the assembly instructions almost entirely, replacing text with sequences of single-line illustrations, free of nuance, built on a universal visual language.
Why IKEA cut the words from its manuals
It's fair to assume this choice wasn't born out of a love for contemporary art or Nordic minimalism, but from a fairly hard-nosed practical and economic calculation:
- Zero translation and localisation costs. A single booklet printed in millions of copies works in Naples the same as it does in Stockholm, Tokyo or Manchester.
- No printing or version errors. No risk of the Italian-language sheet ending up in a box bound for the British market.
- Universal accessibility. The system works regardless of the customer's literacy level or their grasp of technical terminology.
But how does an IKEA booklet actually work when it works (and wind us up when it doesn't)?
The IKEA visual grammar
It uses an extremely rigorous visual grammar built on clear cognitive principles:
Fixed spatial orientation.
The object is always drawn from the same perspective. If in step 3 the piece of furniture is viewed from above and to the left, in step 4 the orientation won't change unless a specific icon clearly signals that the part should be rotated.
Detail discipline.
Only what's needed for the current step gets drawn. Holes that aren't relevant right then are faded out or left off entirely, so as not to overload the user's working memory.
Visual error feedback.
The famous IKEA figures shaking their heads and saying "NO", set beside the character showing the correct posture or action, work directly to prevent mistakes.
The call for help.
The little drawing of the figure holding a phone, calling IKEA support when things get complicated, isn't just practical advice: it's an emotional pressure valve. It tells the user: we know you might get stuck here, it's not your fault, we've got you.
The point for us isn't to stop using words and turn all our manuals into comic strips. The point is to grasp the underlying lesson of IKEA: if you need three paragraphs of text to explain how to slot a pin into place, the problem isn't the text. The problem is how you're presenting the action, or worse still, it's your product's design.
Don Norman and the door that can't tell you whether to push or pull
In his landmark book The Design of Everyday Things (originally published as The Psychology of Everyday Things), Don Norman introduced a concept that's become a design classic: the so-called "Norman door".
All of us, at least once in our lives, have stood in front of the glass door of an office, a bank or a café, seen a shiny metal plate, given it a firm shove and walked straight into the glass because the door actually needed pulling. Or the other way round.
Norman explains that when someone gets a door wrong, the fault isn't theirs. The fault lies with the door's designer.
A well-designed door communicates its function through its physical features without needing any writing at all. If there's a flat plate to push, your hand naturally pushes; if there's a bar handle, your hand grips and pulls it. The perceived properties of an object that suggest how it should be used are called affordances; the visual or tactile cues that specify exactly where the action should happen are called signifiers.
When you need to stick a laminated sign reading "PUSH" or "PULL" in block capitals onto a door just to make it work, that means the design has failed. The sign is an emergency patch slapped on to cover up a design mistake.
How does all this apply to instruction booklets? Directly. Plenty of instruction booklets are long, complicated and impenetrable because they're trying to make up for flaws in the physical product's or the software's design.
If explaining how to set the temperature on a machine means writing: "Press button A for three seconds, wait for light B to flash, press button C twice while holding button A down at the same time", you're not writing a manual: you're providing instructions for defusing a landmine.
A good technical copywriter, before touching the keyboard, should do what smart manufacturers have always done: take the product prototype, put it in the hands of someone who's never seen it before, stick their own hands in their pockets, and keep quiet.
Watch where the person's hand instinctively lands. Watch where their eyes search for the switch. Watch when their face shows hesitation or frustration.
The manual shouldn't have to explain what the product could communicate on its own through better design. The manual should only step in where physical intuition runs out, offering support that's invisible, precise and immediate.
Orwell's six rules applied to the instruction booklet
In 1946, George Orwell published an essay called Politics and the English Language. It was a fierce attack on the political prose of the day, bloated with stock phrases, pompous terms and constructions used to hide thought rather than reveal it.
In that essay, Orwell laid down six golden rules for writing. Rules born for journalism and non-fiction, but that could just as well have been written for anyone drafting technical documentation for a modern business.
Let's go through them one by one, applying each directly to rewriting an instruction booklet:
1. Never use a metaphor, simile or other figure of speech which you are used to seeing in print.
In the booklet: cut out the generic or promotional phrases. The booklet shouldn't say the machine is "solid as a rock" or that installation is "a piece of cake". State exactly how many kilograms the frame holds and exactly how many minutes it takes to fix the four rawl plugs.
2. Never use a long word where a short one will do.
In the booklet: use "Use" instead of "Utilise". Use "First" instead of "As a preliminary step". Use "Find" instead of "Locate". A short word cuts reading time and doesn't tire the eye.
3. If it is possible to cut a word out, always cut it out.
In the booklet: turn "It is recommended that a visual check be carried out to ensure the presence of..." into "Check there's...". Every word you cut is one less obstacle between the user's intention and the correct action.
4. Never use the passive where you can use the active.
In the booklet: turn "The tank must be filled with water by the user up to the maximum level indicated" into "Fill the tank with water up to the MAX mark". The active imperative states the action directly, immediately and unambiguously.
5. Never use a foreign phrase, a scientific word or a jargon word if you can think of an everyday English equivalent.
In the booklet: if your company makes valves and internally calls a component "the extruded branch nipple", remember the end customer will simply call it "the curved metal fitting". If you really do need the technical term for spare parts purposes, put it in brackets after describing the object plainly enough that anyone could recognise it by touch and sight.
6. Break any of these rules sooner than say anything outright barbarous.
In the booklet: clarity and natural phrasing come before the blind application of any rule, however rigidly it's meant. If following a rule makes the sentence unnatural or ambiguous, ditch the rule.
An example rewrite, before and after
Let's look at a concrete rewrite from the workshop floor — staying within Berto's world, because his wire-drawing machine doesn't just work bronze: it also produces pasta that someone, on the other end, will need to store and cook at home.
BEFORE (defensive corporate officialese): "In order to ensure the preservation of the optimal organoleptic characteristics of the product contained within the packaging, it is expressly forbidden to place the same in environments subject to direct sunlight or high levels of relative humidity. Following opening, consumption must be completed within a period not exceeding 72 hours, keeping the container at a temperature between 2°C and 6°C."
AFTER (direct, clean, Orwellian style): "Store this pack somewhere cool and dry, away from sunlight.
After opening:
- Seal the jar tightly.
- Put it in the fridge (between 2°C and 6°C).
- Use within 3 days."
The first version runs to five lines, takes two readings to sink in, and breeds distrust. The second version fits into three bullet points, reads in four seconds, and guides the user's hand with no room for error. The same principle applies to the sheet that comes with Berto's wire-drawing machine: the product changes, the logic doesn't.
Berto exports, Bobby reads it in English: comparing the Italian and UK rules
Back to Berto. After I'd pulled apart the first page of his booklet, he looks at me and says: "Fair enough, Umberto, for clients in Campania or Lombardy I can rewrite it simpler. But starting this month I'm shipping these machines to two distributors in England, one in Salford and one in London near Borough Market. How does it work over there? Do I just run this text through some translation software or is there something I need to watch out for?"
Now we're getting into serious territory. The British market and the continental one share the same goal of consumer safety, but they approach it with regulatory frameworks and cultural sensitivities that an Italian business owner can't afford to ignore.
What UK regulation says
From a post-Brexit regulatory standpoint, official UK government guidance (GOV.UK) on UKCA marking — which sits alongside or replaces CE marking for the UK domestic market — states that manufacturers and importers must ensure every product comes with instructions that are clear, legible and written in English that's easily understood by the end consumer. Putting a product on the UK market with a manual translated into ungrammatical or ambiguous "Inglish" doesn't just land the company an embarrassing commercial own goal: it exposes the importer and distributor to direct action from market surveillance authorities (Trading Standards).
But beyond the law, there's the cultural question.
The cultural difference no law can regulate
Picture Bobby. Bobby's forty-five, runs a fresh pasta workshop in Salford, in the Manchester metropolitan area. He's a practical bloke, works ten-hour days, has a pint at the pub after his shift, and when he buys a machine from Italy he wants two things only: that it works straight away, and that the instructions tell him what to do without wasting his time.
If Bobby opens the box of Berto's machine and finds a literal translation of the Italian officialese ("It is recommended the scrupulous observance of the above-mentioned prescriptions..."), his immediate reaction will be a bitter laugh, followed by a serious loss of confidence.
In the English-speaking world, technical writing has a well-established tradition rooted in the Plain English Campaign: brevity, action verbs, no frills, absolute clarity.
Where the Italian business owner tends to think a long text stuffed with difficult words sounds more "official" and "professional", the British reader thinks exactly the opposite: if you're using difficult words to explain a simple concept, it means you're either trying to pull a fast one on me or you don't actually know what you're talking about.
Berto couldn't just send Bobby in Salford a machine-translated version of his warranty notice. He needed a text built around concrete actions, checked by someone who doesn't just use English to order a drink at a pub bar in Shoreditch, but to build business relationships and technical documentation that stand up to the market.
The practical method: how to write an instruction that actually works
Let's now look at how to turn these thoughts into a repeatable working process for your business. Whether you need to write instructions for B2B software, a designer lamp made in Naples, or industrial machinery bound for export, the workflow doesn't change.
The instruction booklet checklist
- One sentence, one action. No command contains two separate instructions joined by complex conjunctions.
- Imperative verb up front. Every step starts with an action verb (Press, Turn, Open, Connect, Clean).
- Numbered, chronological structure. Numbers (1, 2, 3) are used, never continuous prose paragraphs.
- Consistent vocabulary. The same component keeps the same name from the first line of the document to the last.
- Visual confirmation of the action. Every critical step includes feedback on the outcome ("You'll hear a click", "The green light stays on").
- Warnings kept separate. Real hazards are flagged right next to the specific action, not buried in running text.
- Checked, natural language. The text has been reviewed by a native speaker of the destination country (never a machine translation left unchecked).
Let's see how a set of instructions gets built using this method on a real case: the instructions for using and first servicing an artisan bronze wire-drawing die — the very same machine of Berto's, the one now also made for Bobby.
Practical example: first clean of the bronze die
What you'll need:
- A container of hot water (around 50°C)
- A soft-bristled brush, natural fibre or nylon
- A clean, dry cotton cloth
Note: don't use steel brushes or acidic limescale removers.
Work sequence:
- Unplug the machine. Pull the plug from the wall socket.
- Remove the ring nut. Turn the front ring nut anticlockwise until it comes off completely.
- Take out the die. Pull out the bronze insert by gripping the central pin.
- Soak the piece. Put the die in the container of hot water for 10 minutes. This will soften any dough residue.
- Brush the grooves. Clean the die's holes using the soft brush. Move the brush from the inside outwards.
- Check it's clean. Hold the die up to the light. All the holes must be free of residue.
- Dry it thoroughly. Wipe the die with the cotton cloth until there's no trace of moisture left.
- Refit the die. Slot the insert back into place, pushing it all the way in until you feel it seat properly.
Notice the difference. No subordinate clauses. No legal terms. Just a logical sequence that guides the operator's hands from the moment they pick up the tool to when they put it back on the bench, clean.
The carpenter doesn't use the same plane for oak and poplar
In Caserta I know an old carpenter who's worked wood for fifty years. One day I was in his workshop watching him plane an old oak beam bound for a farmhouse nearby. I asked him why he used three different planes to finish the same surface.
He stopped, wiped his hand across his sawdust-covered forehead and told me: "Umberto, oak is hard, tight-grained, it fights you. Go at it heavy-handed with the wrong blade and you'll tear the grain and ruin the piece. Poplar, on the other hand, is soft — it frays if the blade isn't sharp as a razor. A carpenter who uses the same workbench and the same blade for oak and poplar isn't a craftsman: he's a bricklayer working with wood."
I've thought about that line a lot since.
In our line of work, comms and copywriting for businesses, we often make exactly the same mistake: we treat every reader as if they were the same kind of wood. We write the same manual for the expert technician who's worked on that kind of machinery for twenty years and for the private customer who bought the thing half an hour ago and doesn't even know which end of a screwdriver to hold.
The reader isn't a blank slate for you to pour your technical knowledge onto. The reader is a person with limited attention, a specific set of skills, and a real-world context for reading:
- The beginner needs reassurance. They're after the "Quick Start Guide", want to see the first three clear steps to get the thing running without doing any damage, and need instant visual confirmation at every step.
- The professional user is in a hurry. They'll never read your company's brand story. They want an error code table, a wiring diagram, and a spare parts list with clearly visible order codes.
Designing usable documentation means building a layered structure:
- Quick Start Guide. A single laminated sheet, or a stiff card sitting right on top of the product in the box. Four essential steps to switch it on and check the basic function.
- Full user manual. Available as an essential paper copy or accessible via a QR code straight off the machine, for going deeper into maintenance, fine adjustments and troubleshooting.
- Technical servicing sheet. Aimed at support technicians or authorised distributors.
Working hardwood takes sharpening and patience; working with your business's different audiences takes information architecture.
The booklet nobody throws away
We've reached the end of this look into the most overlooked text in modern marketing.
Let's go back to Berto's workshop for a moment. After two weeks of work, we rewrote his manual from scratch. We ditched the grey photocopy paper and printed an A5 guide on 120gsm uncoated stock, with a clean, readable typeface, clean-line illustrations from our own design team, and a tone of voice that was simple, steady, authoritative but deeply human.
At the top of the first page there's no longer a citation of the civil code articles on warranty forfeiture. There's a simple line: "Thanks for choosing this machine. We built it in San Leucio with the best steel and an obsession for detail. This booklet shows you how to get the most out of it from day one, and how to make it last twenty years. Keep it near the workbench."
Three months later, Berto rings me. It's evening, I can hear the traffic on the Via Appia through his car.
"Umberto, I've got to tell you something," he says. "That client of mine in Salford, Bobby, sent me an email today. His machine turned up three days ago."
"What did he say?"
"He wrote to say the machine's spot on. But the odd thing is, he complimented me on the booklet. Said in thirty years of work he'd never once come across the instructions for an Italian machine written in English so clear that even his youngest lads got it first go, no need to stop and ask him anything."
Berto paused. I can hear his indicator ticking away.
"Know what, Umberto? That booklet cost me a bit extra in design and copywriting. But Bobby's just put in an order for two more machines to send over to his Manchester site."
A well-written instruction booklet isn't a bureaucratic cost. It's the quietest, most effective and longest-lasting bit of advertising your company can put out into the world. It's proof that your attention to detail doesn't stop the moment the invoice goes out, but stays with the customer for as long as they're using what you made with your own hands.
Transparency statement: at Insight ADV, technical writing doesn't exist in isolation from everything else. It works hand in hand with whoever designs the label, whoever lays out the catalogue, whoever shoots the still-life product photography, and whoever handles the packaging the customer holds before reading a single line of instructions — because the booklet they find inside the box has to speak the same language as the catalogue that convinced them to buy. We work with industrial SMEs and advanced craft businesses across Italy and the UK on all of this, from the brand right through to the box and down to the sheet inside it. If your user manual still reads like a forensic report while the rest of your comms speak a different language altogether, we can sit down over a coffee and find the right voice together — the same voice, for every piece of paper that carries your name.
Frequently asked questions
What's the difference between a user manual and a technical data sheet?
The user manual is aimed at the end customer and explains how to install, use and maintain the product safely, in language accessible even to people without technical know-how. The technical data sheet, on the other hand, is aimed at technicians, distributors or qualified installers, and goes into detail on specifications, tolerances, wiring diagrams or spare part codes. They're two different documents for two different audiences: mixing them into a single text is one of the most common mistakes SMEs make.
What is Simplified Technical English, and is it any use to small businesses too?
It's a controlled language born in the 1980s for the aerospace industry, built on a dictionary of around 900 approved words and 53 writing rules, aimed at wiping out ambiguity in technical texts. You don't need to adopt it wholesale to benefit from it: even an SME can apply its basic principles — short sentences, active imperative verbs, consistent vocabulary — and end up with far clearer instructions without needing any certification.
Do instructions for a product sold in the UK legally have to be in English?
Yes. Official UK government guidance requires that products placed on the British market come with instructions that are clear, legible and in English easily understood by the end user. An unreviewed machine translation isn't enough: the risk isn't just looking unprofessional, but also possible action from market surveillance authorities.
How many words should a single instruction have to be effective?
As a practical benchmark, the Simplified Technical English standard sets a limit of 20 words for procedural sentences and 25 for descriptive ones. It's not a requirement for an SME, but it's a great starting point: if an instruction goes over that length, it almost always means it contains more than one action and needs splitting into two separate steps.
Is it compulsory to include images in user instructions?
It's not a general requirement, but for many product categories (machinery, flat-pack furniture, multi-part devices) images cut down on user errors dramatically compared with text alone, because they convey spatial orientation and sequence instantly. The rule of thumb: if a step needs to describe a position, a direction of rotation or how parts fit together, an illustration says in a second what the text would take three lines to explain.
Who's legally responsible if the instructions are badly written?
Responsibility generally falls on the manufacturer or, for imported products, on the importer placing them on the market. Poor or ambiguous user information can, in substance, be treated much like a defect in the product itself, exposing the company to complaints, returns or legal action. For an assessment of any specific case, it's still necessary to consult a solicitor, since regulations vary by product type and destination market.
Is it worth handing the writing of instructions over to an outside copywriter?
It depends on how much time and specific expertise the business has in-house to apply the clarity principles set out in this article. Whoever writes about the product every day often takes steps for granted that aren't obvious to the customer at all: an outside eye, used to putting themselves in the shoes of a first-time reader, helps catch these blind spots before they turn into support calls or bad reviews.
