And why a good prompt isn't a magic phrase, but a structured work instruction.
Microsoft Copilot is often presented as an intelligent assistant capable of summarizing, writing, analyzing, and structuring information in Outlook, Teams, Word, PowerPoint, or Excel.
That's true.
But in practice, many users are disappointed during their first attempts. They ask a simple question, receive an average response, and then conclude that the tool is limited.
The problem doesn't always come from Copilot.
It often comes from how the request is formulated.
A vague prompt generally produces a vague response.
A well-structured prompt produces a more useful, reliable, and actionable response.
That's where a simple method makes all the difference.
At Tomorrow Solutions, we recommend an easy-to-remember structure to quickly improve the quality of interactions with Microsoft Copilot:
RTFCE:
- R = Role
- T = Task
- F = Format
- C = Constraints
- E = Examples
This method allows you to move from an imprecise request to a clear work instruction.
Why Vague Prompts Yield Average Results
Many users start with requests like:
- "Summarize this document"
- "Reply to this email"
- "Prepare a summary"
- "Analyze this meeting"
- "Make me a presentation"
These requests aren't absurd. They're simply incomplete.
Copilot then has to guess:
- what angle to take;
- what level of detail to provide;
- what format to use;
- what tone to employ;
- what to prioritize;
- what to avoid.
Result: the response may be correct but not very useful.
It often lacks:
- precision;
- structure;
- business context;
- level of requirement;
- adaptation to the audience;
- clarity on limits.
In a professional environment, this quickly creates frustration.
The user thinks:
"It's not bad, but it's not directly usable."
And they're right.
A Good Prompt Isn't a Magic Phrase
There's sometimes a somewhat misleading view of prompt engineering.
As if knowing a secret formula was enough to suddenly get impressive results.
In reality, a good prompt is much like a good instruction given to a colleague.
It must explain:
- who should act;
- what they should produce;
- in what form;
- with what limits;
- from what level of example or expectation.
In other words, a good prompt isn't a trick.
It's a well-formulated work instruction.
The RTFCE method precisely helps to structure this instruction.
RTFCE: A Simple Method for Writing Better Prompts
The RTFCE method is based on five elements.
1. R for Role
The role helps frame the posture that Copilot should adopt.
Examples:
- professional communication expert;
- executive assistant;
- project manager;
- senior lawyer;
- management controller;
- transformation consultant;
- HR manager;
- business analyst.
The role influences:
- vocabulary;
- response angle;
- level of formality;
- way of organizing information;
- expected quality.
Example
Instead of saying:
"Write a summary"
you can say:
"Act as a transformation consultant and write a summary..."
The role doesn't change everything by itself. But it immediately improves the relevance of the response.
2. T for Task
The task corresponds to what you actually expect.
It's often the most important part.
A well-defined task is precise and results-oriented.
Examples of useful tasks:
- summarize a document;
- identify decisions;
- list follow-up actions;
- write a response;
- compare two versions;
- prepare an executive summary;
- structure a note;
- extract risks;
- rephrase a text;
- turn notes into an action plan.
The clearer the task, the more usable the response will be.
Example
Instead of asking:
"Analyze this meeting"
you can ask:
"Analyze this meeting and identify the decisions made, open actions, and blocking points."
Here, Copilot no longer has to guess what's expected.
3. F for Format
The format helps avoid responses that are difficult to reuse.
Without indication, Copilot chooses a structure itself. And this structure isn't always suited to your need.
Possible formats:
- table;
- bullet list;
- ready-to-send email;
- executive summary;
- document plan;
- 5-point note;
- action plan;
- slide outline;
- FAQ;
- structured report.
Example
Instead of saying:
"Prepare a summary"
you can specify:
"Format: executive summary in 5 points, then list of risks, then recommendations."
This precision greatly changes the output quality.
The format is what turns a correct response into a directly usable one.
4. C for Constraints
Constraints serve to frame the response and reduce risks.
They are particularly useful in business.
Examples of common constraints:
- do not invent information;
- only cite elements present in the document;
- signal uncertainties;
- distinguish facts, hypotheses, and recommendations;
- stay under 200 words;
- use a professional tone;
- avoid jargon;
- do not make decisions on behalf of the user;
- propose a clear next step;
- remain diplomatic;
- maintain an institutional style.
Example
A good constraint might be:
"Do not invent elements not present in the text and signal any area of uncertainty."
In a professional context, constraints are essential.
They improve not only quality but also usage safety.
5. E for Examples
Examples allow Copilot to understand more precisely what is expected.
They can focus on:
- tone;
- style;
- length;
- level of detail;
- structure;
- type of formulation expected.
An example can be a model, a sentence, a structure, or a representative excerpt.
Example
"Use a tone similar to this example: clear, direct, professional, without excessive jargon."
Examples are particularly useful when you want to:
- reproduce a writing style;
- standardize responses;
- gain consistency;
- produce more homogeneous deliverables.
Simple Example: Before / After
Let's take a common case.
Vague Prompt
"Reply to this email."
This prompt can work, but it lacks framework.
Structured Prompt with RTFCE
Act as a professional communication expert.
Write a clear and diplomatic response to this email.
Format: maximum 3 paragraphs.
Constraints: do not invent information, remain professional, propose a clear next step.
Example of tone: sober, direct, courteous.
The difference is significant.
In the second case, Copilot knows:
- what role to adopt;
- what it should do;
- in what form;
- what to avoid;
- what tone to use.
Five Useful Prompts with the RTFCE Method
Here are some concrete examples that teams can reuse.
1. Prompt for Outlook
Prompt
Act as a professional communication expert.
Write a clear and diplomatic response to this email.
Format: maximum 3 paragraphs.
Constraints: do not invent information, remain professional, propose a clear next step.
Example of tone: sober, direct, courteous.
Why It Works
It transforms a simple response request into a framed, professional, and reusable message.
2. Prompt for a Teams Meeting
Prompt
Act as an executive assistant.
Analyze this meeting and produce a table with:
- decisions made;
- actions to follow;
- responsible person if mentioned;
- deadline if mentioned;
- blocking points.
Constraints: if information is not specified, indicate "not specified."
Why It Works
It avoids vague summaries and produces an immediately usable format.
3. Prompt for a Word Document
Prompt
Act as a transformation consultant.
Summarize this document for a board of directors.
Format: executive summary in 5 points, then risks, then recommendations.
Constraints: clearly distinguish facts, hypotheses, and recommendations.
Why It Works
It adapts the response to a managerial audience and structures information for decision-making.
4. Prompt for a Manager
Prompt
Act as an experienced manager.
Turn these notes into a clear message for my team.
Tone: direct, constructive, professional.
Format: context, decision, next steps.
Constraints: no jargon, no overly corporate phrasing.
Why It Works
It connects Copilot to a real management use, with a more natural communication style.
5. Prompt for Governance or Review Needs
Prompt
Act as an AI governance expert.
Analyze this text and identify:
- sensitive data;
- potential risks;
- points requiring human validation;
- questions to escalate.
Constraints: do not give definitive legal opinions, signal areas of uncertainty.
Why It Works
It frames the expected level of caution and limits the risk of excessive interpretation.
Why This Method Is Particularly Useful with Microsoft Copilot
Microsoft Copilot is integrated into daily work tools: Outlook, Teams, Word, Excel, PowerPoint.
This integration makes it very powerful.
But it also creates an illusion:
"Since it's integrated, it will naturally produce good results."
In reality, integration doesn't replace method.
Even in Microsoft 365, the quality of the result heavily depends on the quality of the instruction.
The RTFCE method helps make Copilot:
- more precise;
- more reliable;
- more consistent;
- more useful in real workflows.
It also helps users progress faster, as it provides a simple structure to replicate.
The Most Common Mistakes to Avoid
Here are the mistakes we often see.
1. Asking for Something Too Broad
Example:
"Make me a summary"
Without further precision, the response risks being generic.
2. Forgetting the Audience
A document for a manager, a lawyer, a client, or a board of directors doesn't have the same level of expectation.
3. Forgetting the Format
Even a good response becomes less useful if it's not delivered in a reusable format.
4. Not Setting Constraints
Without constraints, Copilot can be too long, too assertive, or too vague.
5. Not Reviewing
Copilot remains an assistant.
It can help produce faster, but human validation remains indispensable.
How to Integrate RTFCE into Team Habits
The method becomes truly useful when adopted collectively.
Some best practices:
- share 5 to 10 standard prompts per profession;
- create a mini internal guide;
- document the most useful use cases;
- have AI champions work on recurring prompts;
- integrate the best prompts into training;
- improve prompts based on field feedback;
- link each prompt to a concrete workflow.
The goal isn't for everyone to reinvent their prompts alone.
The goal is to capitalize on what works.
From Prompt Quality to Adoption Quality
The RTFCE method isn't just a writing technique.
It's also an adoption lever.
Why?
Because it helps users quickly obtain useful results.
And the more useful the results, the more usage takes hold.
A bad experience at the start slows adoption.
A good repeated experience accelerates trust, usage, and value.
That's why the subject of prompts isn't anecdotal.
It plays a direct role in the quality of Copilot adoption.
Conclusion: Better Prompting Means Better Working with Copilot
Microsoft Copilot doesn't need complicated prompts.
It needs clear prompts.
The RTFCE method allows you to transform a vague request into a structured work instruction:
- a role to frame the posture;
- a task to specify the objective;
- a format to make the output usable;
- constraints to limit errors;
- examples to improve quality.
A good prompt isn't a magic formula.
It's a more rigorous way of working with AI.
