How to Write a Good Prompt: A 5-Part Framework for Work

Length helps, too. Google found that the most successful prompts in its Workspace tests averaged about 21 words, while people usually typed fewer than nine (Google Prompting Guide 101). So the quickest fix is simple: add detail. Then read the answer, check it and refine the prompt, which is also what OpenAI tells ChatGPT users to do (OpenAI Help Center).

Why a better prompt gets a better answer

An AI model knows nothing about your work unless you tell it. Unless it can see your files or search the web, it can’t know your company, your audience or your goal. A short prompt forces it to guess, and those guesses come out generic.

What the AI companies recommend

The major AI companies give similar advice. OpenAI tells ChatGPT users to be clear and specific and to give enough context (OpenAI). Anthropic’s guide for Claude starts with being clear and direct (Anthropic). Google names four parts of a good prompt: persona, task, context and format (Google).

The framework below builds on Google’s four parts. It folds persona into context, and adds two parts that matter at work: the input you paste in and the limits you set.

A good prompt still needs a check

Even a strong prompt gives you a draft. In Microsoft’s 2026 survey of 20,000 AI users, 86% said they treat AI output as a starting point, not a final answer, and 50% named quality control of AI output as a critical skill (Microsoft Work Trend Index 2026). Plan time to review every answer.

The 5-part prompt framework

Use the five parts in this order. You won’t need all five every time, but the more a task matters, the more parts you should fill in.

Part 1. Context: who you are and who it’s for

Context tells the AI your role, your audience and your goal. For example: “I’m an HR officer at a 200-person logistics company in Surabaya. Most staff read messages on their phones.” Without it, the AI writes for a generic office reader.

You can also give the AI a role, such as “Act as an experienced recruiter.” Google’s guide calls this a persona.

Part 2. Task: the one thing you want done

The task is the verb, and Google calls it the most important part of a prompt. Start with a clear action: write, summarize, compare, rewrite or list.

Add a number when you can. “Write three subject lines” gets a clearer result than “Write some subject lines.” Keep one main task per prompt; if you have several, Google suggests splitting them into separate prompts.

Part 3. Input: the material it should use

Input is your source material: release notes, a survey export, last month’s report. Paste it in or upload the file, then tell the AI to use only that material. That leaves it less room to invent facts.

For long documents, Anthropic suggests an extra step: first ask Claude to pull out exact quotes, then ask it to answer from those quotes (Anthropic). Before you paste anything, remove names, salaries and customer details unless your company has approved the tool.

Part 4. Format: what the answer should look like

Format covers length, structure and tone. Ask for “a table with three columns,” “five bullet points” or “under 100 words,” and name the tone: OpenAI suggests words such as formal, friendly or professional (OpenAI).

If you have a good past example, paste it in. For complex tasks, Anthropic recommends three to five varied examples (Anthropic).

Part 5. Limits: what to avoid

Limits stop common problems before they start: “Don’t invent numbers.” “Don’t use hashtags.” “If you’re unsure, say so.” Google’s guide also recommends constraints such as a character count or the number of options you want.

Copy-and-paste prompt template

Context: I am a [role] at [company]. This is for [audience]. The goal is [goal].
Task: [Verb] [number] [thing].
Input: Use only the material below.
[paste material]
Format: [length], [structure], [tone].
Limits: Don’t [X]. If you’re unsure, say so.

Before-and-after prompts for common work tasks

Here is the framework applied to three real tasks. Each strong prompt uses all five parts.

Marketing: a campaign recap

HR: a policy announcement

Everyday work: meeting notes

How to check and improve the answer

Treat the first answer as a draft, and plan on one or two follow-up prompts.

Five follow-up prompts that work for most tasks

1. “What questions do you have that would help you give a better answer?” (Google’s guide suggests this one.)
2. “What assumptions did you make?”
3. “Which parts are you least sure about?”
4. “Rewrite this for a reader with no technical background.”
5. “Make it 30% shorter and keep the three main points.”

Check before you send

Compare every number and name against your input. Open any link the AI cites. Then read the answer once as your reader would. Google’s guide ends with the same reminder: review the output for clarity, relevance and accuracy, because “the final output is yours” (Google).

Save the prompts that work

When a prompt works well, save it in a note with the date and the tool you used. Next time, swap in new input and reuse it. In a few weeks you’ll have a prompt library for your own job. If you’re new to AI, our guide to learning AI from zero, without coding covers what to learn first.
