Conversation In An Open-Plan Office

Open-plan offices were adopted partly on the argument that removing walls increases conversation. What they mostly changed is who else can hear it.

Every exchange has an audience

In an open room, a conversation between two people is audible to everyone within a radius that is usually larger than either participant estimates.

People adjust accordingly. Anything sensitive, uncertain or critical of a third party gets postponed, moved elsewhere or dropped.

The exchanges that remain are the ones nobody minds being overheard, which are also the ones least likely to require the room in the first place.

Interruption cost falls on the wrong person

Starting a conversation in an open room is cheap for the speaker and expensive for everyone nearby, including people not involved.

Because the cost is distributed and invisible, the person speaking has no signal that they are imposing it, and nobody has a graceful way to say so.

The usual result is not confrontation but withdrawal: headphones, booked rooms and a general drift toward asynchronous messages.

Text absorbs what speech gave up

Conversations that would once have happened across a desk now happen in a chat window between people sitting a few feet apart.

Text is private, interruptible and leaves a record, which suits an environment where speaking has become a semi-public act.

It also strips tone, so disagreements that would have been settled in twenty seconds of speech stretch into exchanges where both sides misread each other.

Noise raises effort before it raises volume

Background speech is the hardest kind of noise to ignore, because language is processed involuntarily and competes for the same attention as the conversation you are in.

Speakers compensate by leaning closer or raising volume slightly, which adds to the ambient level and pushes the next pair to do the same.

Over a day this produces vocal fatigue in people who did not think they had been talking much, since effort rose without any obvious change in how much was said.

The useful conversations are scheduled now

What open plans removed was not the meeting but the unscheduled substantive exchange, which needed a moderate amount of privacy to occur at all.

Those conversations moved into booked rooms, which means they now require a decision, a calendar and a shared free half-hour.

The effect is fewer of them, later, and only for issues someone judged important enough in advance to reserve a room for.
