Writing good prompts means filling in four fields

Two people give the same AI the same task. One gets a message they can send straight away. The other gets interchangeable boilerplate they have to rewrite first.

The difference usually lies neither in the tool nor in the talent. It lies in four pieces of information that appear in one prompt and are missing from the other.

That is the real point: without a blueprint the result stays a matter of luck. Sometimes it fits, sometimes it does not, and nobody quite knows why. Knowing the four turns luck into method – and it takes no perfect phrasing, just four fields filled in.

A prompt is a briefing, not a search query

Imagine working for the first time with an experienced external specialist. Excellent at their craft – but they know neither your business, nor your customers, nor the occasion. Would you call out "write a customer message"? Or would you explain in two sentences what it is about, who it is for and how it should sound?

Exactly that difference decides the outcome with AI too. It responds less to elegant wording than to complete information. What you supply makes the result yours. What you leave out, the AI fills with the average – with whatever half fits most situations.

That takes the pressure out of it. There is no magic phrase to hit. There is only the question of whether four pieces of information appear in the prompt.

The four-field blueprint

Four fields, always the same – whether you are writing a message, sketching a concept or having a table built.

Role. Who should answer? "You are an experienced service advisor." The role selects the vantage point, the depth of experience and the register. The same question sounds different from a service desk than from accounts – and both have their place.

Assignment. What exactly should emerge? Not the topic ("it is about a repair") but the work product: an information message, a draft quote, a checklist. The clearer the result, the less often you get an essay where you needed a note.

Context. The field only you can fill. What does the AI need to know about the situation to stop guessing? Who is involved, what happened, which figures apply, which history matters. This is where the difference appears between a text about some situation and a text about yours.

Format. How long, in what tone, in what shape? Three sentences or half a page, warm or matter-of-fact, prose or bullet points. Format is the most frequently forgotten field – and the quickest to fill.

Together the four make the four-field blueprint: role, assignment, context, format. In our guides it goes by RAKF, from the German Rolle, Aufgabe, Kontext, Form.

Here is how the difference reads. Without the blueprint: “Dear customer, during the inspection of your vehicle we noticed irregularities in the braking system. Please contact us at your earliest convenience.” With the blueprint: “Hello [NAME], during the service we found that the brake discs are worn. Replacing them costs an extra 380 euros. Your car stays with us until we hear from you. Shall we replace the discs while it is here?”

The same four fields carry a completely different task. If you need a long report turned into something you can decide on, the role becomes an experienced department head, the assignment an overview with three options for action, the context the report itself plus the question awaiting a decision, and the format one page with three lines per option. The pattern stays, only the content changes.

Finding the empty field

The blueprint helps twice: while writing and while improving. A mediocre result is usually thin in exactly one place – and that place points to a particular field. Four symptoms – and the field each one points to:

• A tone that comes out too stiff or too promotional → sharpen role or format
• Content that would suit any other business just as well → add context
• An essay where a short message was needed → tighten the assignment
• Wrong length, wrong shape → set the format

That turns improving into diagnosis. Instead of staring at a draft wondering how to put it better, you check four fields, find the thin one and top it up there. Twenty seconds instead of half an hour of trial and error.

That is the real gain. The first attempt need not be perfect – it only needs to be built so the second gets better on purpose.

And because the fields stay the same, a routine grows with every task. Fill the four in a dozen times and you think them while you are still framing the job – the blueprint disappears into habit, the way directions become unnecessary once you know the route.

The template

Copy this frame and fill in the four fields:

That last sentence earns its place. Without it the AI fills gaps plausibly; with it the AI is more likely to ask than to invent.

Where the blueprint reaches its limit

The four fields make sure the AI knows your situation. Whether the result is also correct stays your check: whether a figure was carried over correctly, whether a conclusion holds. With the 380 euros from the example it takes two seconds; with an argument it takes longer – and that is exactly where your professional judgement is needed.

The next step

This blueprint is the base skill most others build on. It carries from meeting minutes to a draft quote.
