Part 2: What is synchronous and asynchronous communication?

Part 2: Asynchronous vs. Synchronous Communication — What’s the Difference?

This is part 2 in our series about asynchronous and synchronous communication. You can read [part 1 here].

How do you communicate with your colleagues?

Do you expect an instant reply?

And do you get annoyed when someone takes way too long to respond?

You’re not alone — this is a common friction point in almost every team.

So let’s tackle it head-on and break down the two types of communication that shape every digital workplace.

There are two (not one, but two) ways to communicate in modern work environments:

• Synchronous communication — when communication happens in real time.
• Asynchronous communication — when communication doesn’t happen in real time.

You’re probably already using a mix of both every day, often without even realizing it.

Sometimes it happens unintentionally — like when you’re too busy to respond to a message until the next day. That’s technically asynchronous, but not by design.

And here’s the thing: unintentional async communication isn’t healthy.

What Is Synchronous and Asynchronous Communication?

You already use synchronous communication daily — video calls, phone calls, quick chats, or in-person conversations.

Asynchronous communication, on the other hand, happens outside of real time. Think of project management tools where people leave comments or updates between meetings. That’s async.

Let’s make it crystal clear:

Examples of

Synchronous Communication:

• Video calls
• Phone calls
• Group chats
• Instant messages (chat, SMS)
• In-person conversations (because yes, having a face-to-face chat asynchronously would be… odd)

Chat and SMS are designed for synchronous use — but they can become asynchronous if someone takes forever to reply (we all know that one person).

Examples of

Asynchronous Communication:

• Email
• Letters (old school, but still counts)
• Team chat tools (like lynes)
• Project management systems (like Trello)
• Comments in shared files (Word, Google Docs, GitHub, etc.)
• Fax (yes, believe it or not, some companies still fax)

How Should You Balance Them?

Both types of communication have their place — the trick is finding the right balance.

Ideally, asynchronous communication should dominate your workflow.

But that doesn’t mean synchronous communication isn’t important — it’s essential for quick decision-making and urgent matters.

The key is expectation-setting.

Don’t pick a side — instead, make sure both work together smoothly.

Asynchronous should lead, with synchronous communication as a support act.

Why?

Because synchronous channels are best for handling urgent issues, while asynchronous communication supports day-to-day workflows — a steady stream of information flowing naturally through your digital workplace.

The key to a successful digital workplace lies in asynchronous work.

That’s just how it is.

The benefits are many — and in the long run, it will help phase out the traditional 9-to-5 mindset, giving people the flexibility to work around their own rhythm and the natural flow of their projects.

But more on that in Part 3.
