If you ask an AI assistant to “write something professional”, it must make several decisions for you. Who is the reader? What are you offering? Which facts matter? What should happen after the reader finishes? A polished answer can still miss the task because the instructions left too much open.
A useful prompt resembles a clear brief to a colleague. It describes the work, supplies the information needed and sets the conditions for an acceptable result. You do not need a collection of mysterious phrases. You need to make the task understandable.
Step 1: Define the finished result
Choose one deliverable before opening the chat. “Draft a 120-word follow-up email to a customer who requested our training outline” is easier to assess than “help me with marketing”.
Include the purpose of the deliverable. Perhaps the message should confirm whether the customer wants an individual course or training for a team. That decision changes both the wording and the final question.
Step 2: Give the assistant the facts it needs
Provide the audience, relevant background, approved offer details and the action you want the reader to take. Remove unnecessary personal information before pasting customer notes. Use an account and data policy suitable for the material you are sharing.
Imagine a small bakery promoting a weekend collection service. The useful facts include the collection area, available products, order deadline and how customers place orders. Describing the bakery as “innovative and exceptional” contributes less than explaining how the service actually works.
Step 3: Specify the format and boundaries
Tell the assistant whether you need an email, a table, a checklist or a short script. Set a sensible length and identify anything it must preserve, such as a price or an approved product name.
Google’s prompt design guidance recommends clear instructions, constraints and examples, with refinement based on the responses you receive. These are useful starting principles for your own experiments. See Google’s prompt design strategies.
Step 4: Show what your voice sounds like
Provide a short sample of writing you own and explain which qualities to retain. You might ask for direct sentences, a warm tone and familiar words. Tell the assistant to keep those qualities while writing fresh material for the new task.
“Professional” can mean different things to different people. A sample makes your preference easier to understand. If your business normally sounds conversational, a paragraph full of corporate language will feel out of place even when the grammar is correct.
Step 5: Use a complete working prompt
Try this example with your own approved details:
Draft a follow-up email of no more than 120 words for a business owner who requested information about our introductory AI workshop. The workshop covers writing prompts, checking outputs and applying AI to routine office tasks. Ask whether the training is for the owner alone or for a team. Use a warm, direct tone and short paragraphs. Do not invent a date, price, accreditation, discount or limited availability. End with one clear question. After the email, list any information I should confirm before sending it.
The prompt identifies the audience, purpose, facts, format and missing information. You can now judge the answer against something more concrete than whether it sounds impressive.
Step 6: Review the result in two passes
First check accuracy. Verify names, figures, dates and promises against your source material. If the assistant added a claim you cannot support, remove it or supply the missing evidence.
Then check usefulness. Does the message answer the reader’s likely concern? Is the next step clear? Would you say these words in a real conversation? Rewrite anything that sounds exaggerated or detached from the business.
Give specific revision instructions. “Reduce the introduction to one sentence and make the final question about team size” is more useful feedback than “make it better”.
Step 7: Save the prompt with a quality checklist
Keep the reusable structure and mark the fields that change between tasks. Save one approved output beside it, along with a short reminder to verify facts and review the final call to action. Record problems you repeatedly need to correct.
Begin with one task you do every week. Compare the total time spent drafting and reviewing with your normal process. The value of a prompt becomes clear when it helps you produce work you can confidently use. Coded TV’s AI training can help you practise this approach with everyday business tasks.
