Async vs sync communication: when to use each

Not every conversation needs a meeting. Choosing between asynchronous and synchronous communication saves hours a week.

Part of Async video messaging

Short answer

Use sync (live) communication for urgent, sensitive or highly interactive talks. Use async (recorded or written, answered later) for updates, explanations and feedback.

Definitions

Sync happens live: a call, a meeting, a quick chat. Async happens on each person's own time: a document, a message, a recorded video.

Why video helps async

Text loses tone and context. A short screen recording with your voice shows what you mean, and the viewer can watch when it suits them. RecBeam adds transcripts, captions and search, so a recording can be skimmed, and viewers can react and comment under it.

How to start

  1. Pick one recurring meeting that is mostly updates and replace it with recorded updates.
  2. Record in Chrome and share the link. See how to send a video message.
  3. Agree how long people have to respond.
