Could Someone Else Explain What You Built?

An item with no due date is sitting on the Friday list.

Picture a small internal helper you built with AI. Every Friday, it puts the work waiting for a decision in the usual place. Nobody has to chase you for the list. Your colleague can open it, find the information behind it, and use it in the normal meeting.

Then they point at that undated item.

“Why is this here? It isn’t due on Friday.”

In this example, the helper has done exactly what you intended. The item belongs because it is waiting for a decision. A due date has nothing to do with getting onto the list.

You know that. The record your colleague is looking at doesn’t make it clear.

That is a different kind of dependence on you. The work runs without you touching it. The explanation still needs you in the room.

The working list still contains a human choice

If you’re leading a team and building small systems to help it, a working result feels like the finish line. The list arrives. People can use it. You can get back to something else.

Fair enough. Those are useful things to have working.

Here’s the thing. You also made a choice about what the list is for. And your colleague needs enough of that choice to make sense of what arrives.

Florian Herrengt’s essay about AI and software raises a useful concern here: working software still needs people who understand its choices.

For a team leader, that concern can be very ordinary. Someone asks why an item belongs on a list, and the person who built it is the only person who can answer.

In The Station Plan, the work and the judgment have different homes. The stations do the work. The Pass routes it and manages the handoffs. The Chef, the human at the center, holds the judgment about what the kitchen is trying to produce.

Getting a list into the right meeting doesn’t settle why a particular rule belongs in that list. Somebody made that business choice. The people carrying the responsibility need to be able to find it.

You don’t have to make everyone a builder. You do have to make an important choice understandable to the person who will be asked about it.

The explanation has to survive a change of person.

Friday is the reading day

Stay with the undated item. Your colleague sees a Friday list and supplies a reasonable interpretation: “This tells us what’s due by the end of the week.”

Under that interpretation, the item looks wrong. It has no deadline. Why would it be here?

Now open the rule the helper actually uses. It includes work marked as waiting for a decision, whether or not a due date has been entered.

The reason, in our example, is to keep blocked work visible even when nobody has given it a deadline. A missing date shouldn’t make a waiting decision disappear from the meeting.

Friday is when people read the list. Waiting is why the item qualifies.

Yeah. That small distinction changes the meaning of the whole thing.

The colleague doesn’t need a tour of every instruction used to build the helper. They need to connect this item to its waiting status, and that status to the purpose of the list.

“It belongs because we’re waiting on a decision. We still need to see it even though nobody has entered a date.”

That explanation fits the current rule and the reason behind it. It also explains the detail that seemed odd a minute ago.

Call it a due-date report and you’ve given them a tidy explanation of a different system. The words sound sensible. The item still doesn’t make sense.

The record has to show which choice stayed

Maybe you saved the conversation where you built the helper. Maybe there’s already a useful note beside it. Start there.

You might have discussed deadlines in an early version, then changed the rule to focus on waiting decisions. Both ideas can be sitting in the same conversation. Finding the word Friday won’t tell your colleague which choice you kept.

The history may contain the answer. Actually. The useful part is being able to identify the answer inside that history.

If an existing note already says what the current rule is and why you chose it, you may have everything you need. Point your colleague to that note. See whether it explains the undated item.

If the note just says “Weekly Friday report,” you can see why the question came up.

You can also see why asking AI to write a friendly overview is only part of the job. An overview that repeats the due-date assumption would make the wrong explanation easier to read. Someone who knows where to check has to compare it with the current rule.

Does that make sense?

The goal is an explanation someone can follow back to what the helper does and the choice it serves. A plain sentence beside the rule may do that. A long conversation may do it too, if the adopted choice is easy to find.

Length doesn’t answer the question. The colleague’s ability to explain this item does.

Put that useful explanation where the colleague already goes to understand the list. Having the answer in your personal notes still leaves them asking you where to look when the same question comes up.

Don’t fill an old gap with a new story

In our example, we know why waiting items qualify. In your system, you might find the rule and still be unable to establish why it was chosen.

Keep those two findings separate.

“It includes every waiting item. I haven’t found why we chose that.”

That’s useful. You can now ask the person who made the choice, or the person responsible for deciding whether it still serves the team.

What you don’t have yet is a history you can confidently retell.

A builder might remember choosing the rule for one reason. An old note might record another. The team might decide today that the rule makes sense for a third. Those are different things, and the explanation should say which one you have.

Here’s the thing. A reasonable reason today doesn’t establish what happened when the helper was built.

You can decide to keep the rule because it keeps undated waiting work visible. Record that as today’s decision if that’s what happened. You haven’t recovered an old reason simply by finding one you like.

Right? This is where a convincing paragraph can hide the very gap you were trying to find.

Let the other person keep the notes open

Pick one small, low-risk system and the colleague who would normally cover it. Use the records you already share.

Choose one result worth understanding. An item with no date is useful because it makes the rule visible. A perfectly ordinary item can work too, as long as there’s a meaningful choice to explain.

Ask: “What made this qualify, and why do we want it included?”

Let your colleague keep the notes open. This isn’t a memory test. You’re finding out whether the explanation available to them supports the responsibility you expect them to carry.

Then compare what they say with the current rule and whatever establishes its reason. Listen for the connection, not your favorite wording. They may explain the waiting item more clearly than you do.

If the connection holds, leave the useful record alone.

If they call it a due-date report, find where that interpretation came from. In our example, the title gives them a reading day while the record leaves the inclusion rule unclear. Put the distinction beside the rule: waiting decisions belong, including undated ones, so blocked work stays visible.

Have them explain that part again. If the reason is still unknown, keep that gap visible and name who can settle it.

That’s the Monday move. One result, one explanation, one missing link repaired or brought into view. You haven’t proved the colleague can handle every problem the system might have. You’ve made one important choice easier to understand.

A Friday list can arrive exactly as intended and still leave the team depending on its builder for the meaning of one line.

Start with that line.
