Why Async Communication Beats Meetings (Almost Always)

The best engineering teams I've worked with share a common trait: they treat meetings as a last resort, not a default. Everything that can be async is async. The productivity difference is staggering.

Updated January 2026: Added Meeting-vs-Async Decision Matrix for team calibration.

Remote work forced many teams to experiment with asynchronous communication. Some discovered what I've observed across dozens of companies over decades: most meetings are waste disguised as work. The truth is, the information could have been an email. The decision could have been a document. The status update could have been a Slack message.

Here's what I've learned about why async works and when it doesn't.

The Hidden Cost of Meetings

A one-hour meeting with six people isn't one hour. It's six person-hours, plus context-switching overhead for everyone involved. Research suggests it takes 23 minutes to fully recover focus after an interruption. According to Microsoft's New Future of Work research, meeting-free days show a 78% reduction in meeting volume and 22% increase in focused work. A meeting in the middle of the afternoon destroys two productive hours, not one.

The most expensive person in the meeting isn't the most senior - it's the one doing deep work that gets interrupted. Engineers in flow state are exponentially more productive than engineers in meeting mode. Every meeting is a tax on that productivity.

Teams that default to meetings are constantly paying this tax without realizing it. The calendar fills up. The "real work" gets squeezed into the gaps. People start coming in early or staying late just to get uninterrupted time.

What Async Actually Means

Async communication isn't just "send an email instead." It's a fundamental shift in how information flows through an organization.

The key principles:

• Write things down. Decisions, context, reasoning - all documented. Not buried in chat history, but in findable, permanent locations.
• Response SLAs, not real-time expectations. "Reply within 24 hours for operational items, 72 hours for strategic" is a reasonable policy. "Reply immediately" is just meetings with extra steps.
• Assume the reader doesn't have context. Every async message should be self-contained enough that someone can understand it without having been in a previous conversation.
• Make decisions explicit. Not "we discussed and agreed" but "the decision is X, for reasons Y, with owner Z."

When Meetings Actually Make Sense

I'm not arguing for zero meetings. Some situations genuinely benefit from synchronous communication:

Relationship building. Trust develops through real-time interaction. New team members need face time. Cross-functional relationships need cultivation. You can't async your way to psychological safety.

Complex negotiation. When positions are far apart and nuance matters, real-time back-and-forth is more efficient than async rounds. The key word is "negotiation" - if it's just information transfer, it doesn't need a meeting.

Brainstorming (done right). Generative sessions where ideas build on each other can work synchronously. But most "brainstorms" are actually just people taking turns talking, which works fine async.

Crisis response. When speed matters more than documentation, synchronous coordination is necessary. But this should be rare, not daily.

The Status Meeting Trap

The most common meeting waste is the status update. Everyone goes around the room reporting what they did this week. Nobody learns anything they couldn't have read in a Slack channel. An hour of collective time is burned so a manager can feel informed.

The fix is simple: async status updates. Each person posts their update in a shared channel. The manager reads them. Questions get asked in threads. The meeting that used to take an hour takes five minutes of writing and two minutes of reading.

Some teams resist this because "it's important to see everyone." That's relationship building, which is valid - but don't pretend it's about status updates. Call it what it is and schedule it appropriately.

Documentation as Communication

The highest-performing async teams have a culture of documentation. Not documentation as bureaucratic overhead, but documentation as primary communication.

Decisions get written up with context and reasoning. Design docs precede implementation. Post-mortems capture lessons. The organizational knowledge lives in documents, not in people's heads or lost Slack threads.

This has compounding benefits. New hires can onboard from documentation. Decisions can be revisited with full context. The organization develops institutional memory that survives turnover.

The investment is real - writing takes longer than talking. But it scales better. A well-written document can inform hundreds of people. A meeting can only inform whoever was in the room.

Why Most Teams Don't Do This

If async is so great, why don't more teams adopt it? A few reasons:

• Writing is harder than talking. Organizing your thoughts into clear prose is more effort than just verbalizing them. Many people avoid writing because it exposes unclear thinking that speaking can obscure. In writing, there's nowhere to hide.
• Managers like feeling busy. A calendar full of meetings looks like work. A manager who mostly reads and writes looks like they're not doing anything, even if they're more effective.
• Async requires discipline. You have to actually read what people write, write clearly, and resist the urge to "just hop on a quick call" when writing feels hard.
• Culture is sticky. Organizations that grew up with meeting culture find it hard to change. The people who succeeded under the old system succeeded partly by being good at meetings.
• The tooling defaults to meetings. Calendar applications make scheduling trivially easy. The infrastructure for async work requires more setup and doesn't come pre-installed.

We optimize for what's easy, and meetings are easy to schedule even if they're hard to make productive.

Making the Transition

Shifting to async-first doesn't happen overnight. Teams that try to flip a switch usually fail. The better approach is incremental: pick one meeting type and replace it with an async alternative. Start with status updates - they're the easiest win.

Establish clear response time expectations upfront. "Non-urgent async messages get responses within 24 hours" removes the anxiety of wondering if anyone saw your message. Managers need to model the behavior they want - if leadership keeps scheduling meetings for things that could be documents, the team will follow.

The Hybrid Reality

Most teams will end up somewhere in the middle. Some meetings, some async. The key is intentionality - choosing the right mode for each type of communication rather than defaulting to meetings because that's what calendars make easy.

The question to ask before any meeting: "Could this be a document?" If yes, make it a document. If genuinely no, make it a meeting with a clear agenda and minimum necessary attendees. Cancel meetings where the agenda is unclear or where the outcome could have been achieved through written communication.

The Calendar Test: Run this scorecard on your last week's meetings. How many scored under 4? That's your waste percentage.

The teams that ask this question consistently end up with 50-70% fewer meetings. According to Loom's user research, 62% of users report that async video helps them eliminate low-value meetings entirely. The productivity difference is visible within weeks. Engineers get their mornings back. Deep work becomes possible during working hours instead of requiring early mornings or late nights. The work itself improves because people have time to think.
