Previously, I wrote an article titled "The Four Faces of Company Copilot." That wasn't wrong, but it was incomplete.
Even if you organize it into four faces, the view for those who say it's "mediocre" hardly changes. Just knowing where everything is doesn't make your work even a millimeter lighter. It's like having a map but not yet starting to walk.
"It's convenient, sure. But in the end, isn't ChatGPT enough?" I've heard this phrase many times. It can summarize. It can draft emails. But that's it. Despite the high price the company pays, your overtime hasn't decreased.
To be honest, there was a time when I believed that evaluation too. "It's just ChatGPT that can read internal data." I categorized it that way and didn't think further.
Now I understand. This was like hiring an excellent subordinate and just asking them "What can you do?" every day before letting them go home. The day ends while you're just confirming their abilities. Not a single task gets reduced.
And the fifth face is not the name of a new feature. It's simply stopping "asking" Copilot and changing to "handing over." That's all.
This time, I will reveal the true identity of that fifth face—the Agent—and the "Delegation Model" you can use starting tomorrow in a copy-pasteable format. By the time you finish reading, Copilot will change from a suggestion box into a partner that brings back finished results. Let's begin.
Chapter 1: Four Faces Were Not Enough
First, let's review the previous answer.
The four faces were a map of Copilot's "location." Is it in Chat, inside an app, an agent you made yourself, or a system managed by the company? You can organize where it is with that.
But knowing the location doesn't change the relationship. The fifth face is not about location; it's about the relationship.
You might think, "Agents were already included in those four, right?" That's correct. Agents as a product have existed for a while. Copilot Studio for creating your own sidekick and features for batch processing in Excel are already running. The latter was renamed to "Edit with Copilot" in March of this year.
The problem is that even though they exist, they aren't being used.
The proof is in Microsoft's official release notes. In June 2026, these features were added for administrators:
Feature ①: Bulk Installation of Agents
Administrators can now use rules to distribute agents to all users in the organization at once.
Feature ②: Automatic Reassignment of Orphaned Agents
A system was created to automatically reassign agents whose owners are no longer present to the appropriate manager.
These two things mean one thing: The company is filled with agents that were distributed but never used. These features are only designed under that premise.
Let me be clear. The fifth face is not something you are going to buy. It has already been distributed; it just hasn't been opened yet.
Now that we've confirmed you "already have it," let's look at why it's not being used despite having it.
Chapter 2: The Rift Between the "Asker" and the "Delegator"
Same license, same app, same model. Yet, there will be a decisive difference in workload a year from now. The dividing line is just one thing.
Are you asking, or are you delegating?
The Asker confirms "what can be done" with Copilot. "Summarize this document," "Fix this text." What comes back are fragments. You receive them, paste them, organize them, and finish them. The subject of the work remains you until the end.
The Delegator throws the "job to be done" as a whole. You state the goal, tell it where the materials are, and specify the format of the deliverable. What comes back is not a fragment, but a finished product.
These two are completely different acts, even if they are both called "using Copilot."
To be honest, I was bad at this "delegating" for a long time.
During my corporate days, I was transferred from the sales department to the HR department by presidential order. Three months later, the sales of the department I left were cut in half. I was called back, and in the first month of my return, I brought it back to 1.5 times the previous month. From 50 million to 75 million yen.
Looking at the numbers alone, it looks like a heroic tale. It's not. It was proof that I had built a department that couldn't run without me. I was delegating tasks, not the job. I held onto all the judgment myself.
It was all my fault. The more inconvenient the point, the more likely it is to be correct. Someone who couldn't delegate to subordinates can't delegate to AI. The reason for not being able to delegate wasn't the other party's ability. I just didn't know how to delegate.
Copilot isn't mediocre. The jobs you are delegating are just too small.
Chapter 3: Demonstration — Comparing the Same Job by "Asking" vs. "Delegating"
Words alone are hard to convey, so let me show you.
One honest point first. What I'm writing here is about Microsoft 365 Copilot, which you contract as a company and which reads across internal files and meetings. Since I am independent and don't have a corporate environment, the following is organized based on specifications verified in official documents and screens I've actually seen at consulting sites.
【When Asking】 Question: "Tell me about the recent moves of our competitors."
What comes back is this: "To understand competitor trends, it is effective to regularly check press releases, financial results, and social media posts. It is important to organize differentiation points and analyze them against your company's strengths."
—It's correct. But this is a general theory you've read somewhere. It's an average answer that's the same for everyone. This is where most people judge it as "useless."
【When Delegating】 You throw the same theme as a whole job.
1Please organize the recent moves of our three main competitors and create materials to be used in next week's sales meeting.2Refer to the proposal materials in the internal sales shared folder and the meeting notes from the last three months. For any missing information, search the internal meeting records.3Please provide the following three items as finished files:4① A comparison table summarizing the recent moves of the three competitors in one line per company.5② Points where our company is losing and points where we are winning.6③ Three slides for the meeting (Conclusion, Evidence, Next Steps).7For items where the source material cannot be confirmed, clearly state "No data" and do not fill them in with speculation.
What comes back is not a summary. It's a table, discussion points, and slides you can take straight into a meeting. All you have to do is check the content and fix it.
Same Copilot, same theme. The only difference is whether you sought an answer or delegated a job. That's it.
Don't worry. No programming is required. No difficult settings are needed. For the first time, try it with a job you know best. This is because you can judge the quality yourself.
Now that we have the actual "how to delegate," let's narrow down the conditions for reproducing that delegation every time to three.
Chapter 4: Three Conditions for Successful Delegation
The conclusion I reached while verifying official specifications is this. You only need three things when delegating.
Condition ①: Hand over the Goal
Instead of "summarize," say "create materials for making a judgment at the meeting." State the purpose, not the task name. The moment you specify the procedure, the other party reverts to being just a worker.
Condition ②: Hand over the Location of Materials
Which folder to look at, which meeting records to search. This is Copilot's home turf that external AIs cannot mimic. Microsoft officially explains that by combining with Work IQ, the output is grounded in the company's context.
Condition ③: Decide the Return Destination
Should it reply with text in the chat box or output as a file? Unless you specify the form of the deliverable, Copilot stops at "talking."
When these three are met, work will progress even if you step away. In fact, current Copilot has changed to that kind of structure. You can now schedule regular instructions to agents, and you can check the progress of time-consuming tasks from the Windows taskbar.
A system where multiple agents collaborate to respond to a single request has also been introduced. Furthermore, Copilot Chat will suggest an agent if there is one in the company that fits the content of the request, even if you don't call it by name.
In other words, the tool side is already standing on the "premise of being delegated to." The only thing not catching up is the design on the delegating side.
One more thing. If you feel the delegated work is weak, adding this one sentence works wonders:
1Regarding the deliverables you just produced, please indicate the internal documents used as evidence for each item. If there are parts filled in with speculation, please honestly write "speculation." Then, identify the weakest part of this deliverable and produce a revised version.
Furthermore, you can now choose who to delegate to. Claude Opus 4.8 from Anthropic was added on May 28, and Claude Sonnet 3.5 was rolled out to Copilot Cowork and PowerPoint Copilot on July 2. However, which model appears on which screen depends on the region and company settings. Please check with your company administrator.
Based on my experience paying for and comparing all major AIs, Claude is a step ahead in the naturalness of Japanese. If you want it to finish a text that a human will ultimately read, it's worth choosing when you can.
You don't need to remember everything from 1 to 10 before starting. Learning while doing is the fastest way.
Summary: The Fifth Face Appears the Day You Stop "Asking" AI
This time, I wrote about the "fifth face" that follows the four faces. One last time, the core of this article:
The fifth face is not a feature you sign a new contract for. It is a face that has already been distributed and not yet opened. The key to opening it is not settings or prompt techniques, but changing our stance from "asking" to "delegating."
As long as you keep using it as a suggestion box, Copilot will forever remain a "somewhat convenient chat." It becomes a partner only the moment you delegate a job.
That said, you don't need to delegate everything at once. There is only one thing to do.
Tomorrow, choose just one of your jobs and instead of saying "tell me," say "make it and output it as a file."
That's all. Once you see a finished product come back, you won't be able to go back to the way of just asking questions and letting it go home.
Copilot, Claude, and Gemini are all evolving really fast. Rather than trying to keep up with the latest on your own, it's overwhelmingly faster to learn from those who are practicing it.
Thank you for watching until the end.
【📣Announcement📣】
I will be holding a seminar demonstrating how to write "X articles" that changed my life.
I started operating X in April 2025, and for the first four months, my follower count only increased by 139. After that, I struggled for 11 months without much growth.
However, in the 12th month. When I started posting "X articles" from March 15, 2026, my follower count increased by 6,609 in just two weeks from March 15 to March 31.
From there, my life changed completely:
❶ X creator revenue is over 300,000 yen every month
❷ Multiple requests for X operation consulting
❸ Multiple requests for AI consulting
❹ Requests to appear on TV programs
❺ Requests for book publication...etc.
Various jobs came flooding in, and my life was transformed by "X articles."
I will conduct a seminar on how to write such "X articles" in a demonstration format. I will share my computer screen and explain how I actually write them.
Also, I have prepared a huge special present limited to the seminar.
