"This meeting could have been an email" has become the universal workplace joke. But behind the humor is a real question most teams never systematically answer: when does synchronous communication actually justify its cost?
A 30-minute meeting with 6 people at $50/hour costs $150. An email costs approximately nothing. The difference isn't just money — it's 3 hours of collective human attention. Here's a framework for making the right call.
The Meeting Necessity Test
Before scheduling a meeting, run through these four questions. If you can't answer "yes" to at least two of them, it should probably be async.
1. Does this require real-time back-and-forth? Brainstorming, negotiation, complex problem-solving, and sensitive conversations benefit from real-time interaction. Status updates, information sharing, and simple decisions almost never do.
2. Do all invitees need to hear each other? If only 2 out of 8 people will actively participate and the rest are "just listening," those 6 people should get a summary instead. Every additional attendee multiplies the cost while adding diminishing returns.
3. Is there a time-sensitive decision that's blocked? If a decision is genuinely blocking work and needs multiple perspectives, a meeting can be faster than an async thread. But "time-sensitive" means hours, not days. If it can wait until tomorrow, write it down.
4. Does the topic benefit from emotional nuance? Giving difficult feedback, resolving conflict, celebrating wins, building relationships — these are legitimately better synchronous. Reviewing a spreadsheet is not.
What Should Always Be Async
Status updates. "What are you working on?" should never require a meeting. A shared document, a Slack thread, or a project management tool handles this with zero cost. If your standup is just people reading their task list aloud, replace it with a written check-in.
Information broadcasts. If one person is talking and everyone else is listening, that's a recording, not a meeting. Record a 5-minute video, send it out, let people watch at 1.5× speed on their own schedule.
Document reviews. "Let's go through this deck together" is almost always less efficient than "read this by Thursday and add comments, then we'll meet for 15 minutes to discuss the open questions." The pre-read approach cuts meeting time by 70% and produces better feedback.
Simple approvals. Yes/no decisions with clear context don't need a meeting. Send the proposal with the relevant information and ask for a decision by a deadline.
When Meetings Are Worth Every Dollar
Not all meetings are waste. Some meetings create more value than they cost:
Kickoffs for new projects where alignment and shared understanding prevent weeks of misalignment later. Retrospectives where honest team reflection leads to process improvements. Creative sessions where ideas build on each other in real time. Difficult conversations where tone, empathy, and immediate response matter.
The key difference: these meetings have a clear purpose that specifically requires synchronous interaction, not just a topic that someone decided to "discuss."
The 3-Question Pre-Meeting Filter
For every meeting you're about to schedule, write down: (1) What specific outcome does this meeting need to produce? (2) Why can't this outcome be achieved asynchronously? (3) Who is the minimum number of people needed to achieve it?
If you can't answer all three clearly, cancel the meeting. Write a message instead. Your team will thank you — and you can see exactly how much you saved with our meeting cost calculator.
