F2F interactions plunged by about 70% in both companies. Meanwhile, email and messaging activity spiked. When people were placed closer together so that they’d talk more, they talked less.

On one hand, you think: Of course, moving people closer together will lead them to collaborate more! That’s just basic sociology. On the other hand: No, look at subways or airplanes—when people are crammed in together, they find ways to retain some privacy through headphones or books or deeply unwelcoming glances.

“Get your model out there where it can be shot at. Invite others to challenge your assumptions and add their own …. The thing to do, when you don’t know, is not to bluff and not to freeze, but to learn. The way you learn is by experiment—or, as Buckminster Fuller put it, by trial and error, error, error.”

we don’t succeed by foreseeing the future accurately. We succeed by ensuring that we’ll have the feedback we need to navigate.

Feedback loops spur improvement. And where those loops are missing, they can be created.

They had a facilitator run the meetings, using a new structured agenda that included a segment in which every participant shared something positive from the previous week.

Beyond the structured agenda, though, they added a feedback loop. At the end of every meeting, every attendee verbally scored the meeting from 1 to 5. Outliers were asked quickly what had made the meeting unusually helpful or unhelpful.

Beyond the structured agenda, though, they added a feedback loop. At the end of every meeting, every attendee verbally scored the meeting from 1 to 5. Outliers were asked quickly what had made the meeting unusually helpful or unhelpful. When people complained about something—a discussion going on too long, a problem not being resolved—those issues got addressed.

Can we create closed feedback loops so that we can improve quickly? Is it easy to reverse or undo our intervention if it turns out we’ve unwittingly done harm?
