The Corridor Committee: What Your Firm Decides Once the Agenda Stops

The scheduled meeting ends at 11:00. By 11:12, three people are standing by the kettle having the real conversation. Nothing dramatic is happening — no crisis, no row — but a decision is being made, or remade, without an agenda. In a small UK firm, this is one of the most ordinary things in the week. It is also one of the easiest costs to miss.

On a 168-hour canvas, the diary looks tidy. The meeting is booked, the invite is sent, the hour is blocked out. What the calendar never shows is the debrief afterwards: the quick follow-up call, the Slack thread that turns into a second meeting, the chat in the stairwell that quietly changes what was agreed. These after-meetings are not automatically waste. They can be where sense gets made. But when they repeat the same conversation, they start charging rent.

Why the after-meeting hides in plain sight

Informal debriefs feel efficient because they are short and unpadded. Nobody has to book a room. Nobody has to prepare a deck. That is precisely why they escape scrutiny. A ten-minute corridor chat does not look like a meeting, so it does not get counted like one.

In a small firm, the same people often do several jobs. The person who chaired the client review is also the one who answers the question about it afterwards. The operations lead who sat through the planning session is also the one who explains it to the team. That overlap is useful, but it can create a shadow meeting schedule — one that never appears in anyone's calendar and never gets reviewed.

The cost is not only minutes. It is decision drift. A meeting ends with a loose agreement. The corridor chat tightens it, changes it or reverses it. The people who were not in the corridor then work from the wrong version. A week later, everyone meets again to work out what actually happened. That is the loop repeating.

Run a one-week after-meeting audit

Pick five working days. Keep the audit light enough that people forget they are doing it. You are not trying to police conversation; you are trying to see where decisions actually travel.

For each scheduled meeting, note any conversation that follows within roughly two hours. Include corridor chats, phone calls, instant-message threads that turn into a proper discussion, and the quick huddle by someone's desk. Record only a few things:

• which meeting it followed;
• who was involved;
• how long it lasted;
• what triggered it;
• whether a decision was made or changed;
• whether that decision and its owner were written down anywhere.

A shared note or a sheet of paper is enough. At the end of the week, count the total minutes. Then count the person-minutes, because a ten-minute chat between three people is thirty minutes of collective attention, not ten.

A realistic example: ten after-meetings averaging eight minutes, each involving two or three people. That is around three hours of person-time before you add the follow-up calls. In 168-hour terms, two hours in one person's week is about 1.2%. But if the same two hours touch four people, it becomes closer to half a working day of collective attention. That is the number worth showing a small firm's leadership team.

Spot the repeat debrief

The audit is not about banning the kettle. It is about finding patterns. Look for these signals:

• the same meeting produces the same follow-up chat every week;
• a decision is made in the meeting, then softened or sharpened afterwards;
• two people leave with different versions of the same agreement;
• someone asks for another meeting to clarify what the first meeting meant;
• the action owner is obvious to everyone in the corridor and invisible to everyone else.

One repeat debrief is a conversation. Three is a process gap. If the same people keep having the same follow-up discussion, the original meeting is not finishing its job. It is ending on time but not closing the loop.

Replace the debrief with a decision-and-owner note

The fix does not need to be a new system. It needs a last two minutes in the meeting. Before anyone stands up, write three lines:

• Decision: what has been agreed, in plain English.
• Owner: who is doing the next thing.
• By when: the date it will be done or brought back.

If there is no decision, write that down too: 'No decision today. Priya to bring two options by Thursday.' That is still a useful close. It stops the corridor from becoming the unofficial decision chamber.

This is not formal minutes. It is a short note that travels. Put it in the same place every time — a shared document, a project channel, a weekly email — so people know where to look. The aim is not to capture every nuance. It is to make the agreed version visible to everyone who needs it, including the people who were not by the kettle.

Keep the informal bit, lose the repeat

Corridor conversations are not the enemy. They build trust, release tension and sometimes solve problems faster than a booked meeting ever could. The point is to stop them from becoming the place where decisions go to be remade.

When an after-meeting happens, ask one light question: 'Is this already in the note?' If it is, you can carry on chatting. If it is not, add the new decision and owner to the note. That single habit keeps the informal warmth of a small firm without letting the shadow meeting schedule run the week.

After a fortnight, review the audit again. You may not eliminate every debrief. You probably should not try. But if the repeat conversations drop and the decision note becomes the default, you have given back a few hours of collective attention. On a 168-hour week, that is not a rounding error. It is room to think.
