The async handoff: passing work across timezones without losing context

You finish your workday at 5pm in New York. Your teammate in London starts at 9am their time—which is 4am your time. You're both asleep when the other is working. This is the reality of global teams: you rarely overlap, but work still needs to flow.

The solution isn't more meetings. It's a disciplined async handoff that makes context transfer seamless. When done right, your teammate can pick up exactly where you left off without a single live conversation.

The handoff document (your secret weapon)

Every handoff starts with a short document that answers three questions:

1. What's done? List the concrete outputs: code merged, design approved, customer call completed. Be specific enough that someone can verify it.

2. What's blocked? Name the exact blocker and what you tried. "API returns 500 error" is better than "having issues." Include error messages, screenshots, or links to relevant threads.

3. What's next? The next person should know their first task within 30 seconds of opening the doc. If it's ambiguous, you haven't finished the handoff.

Keep it short. A good handoff doc is 3–5 bullets, not a novel. If it takes longer than 2 minutes to write, you're including too much context that should live elsewhere.

The timing that makes it work

Send the handoff at the end of your workday, but structure it so your teammate sees it at the start of theirs. This means:

• Post it in a shared channel or doc that they check first thing
• Use a format that's scannable (bullets, not paragraphs)
• Include links to the actual work (PRs, designs, tickets) so they can dive in immediately

If your handoff arrives in the middle of their day, it gets buried. If it arrives at the start, it becomes their roadmap.

The context that actually matters

Most handoffs include too much background and not enough action. Your teammate doesn't need the full history—they need:

• The current state (where things stand right now)
• The decision that was made (if one was needed)
• The next step (what to do first)

Everything else—the discussion, the alternatives considered, the backstory—belongs in the ticket, PR description, or design doc. Link to it, don't repeat it.

When to break the async rule

Some handoffs need a live moment:

• The work is ambiguous and needs real-time discussion
• There's a blocker that requires immediate attention
• The context is too complex to write down quickly

But here's the key: schedule that live moment during your actual overlap window. Don't ask someone to join at 11pm for a handoff that could have been async. Use timezoners.com to see when you both have working hours that align, then book a short sync during that window.

The test: can they start without you?

A good handoff means your teammate can begin work immediately without asking questions. If they're messaging you for clarification, the handoff wasn't complete.

Try this: write your handoff, then read it as if you're the person receiving it. Can you start working right away? If not, add the missing piece. Usually it's the "what's next" that's too vague.

Making it a habit

The best global teams make handoffs automatic. They don't think about it—they just do it. This happens when:

• The format is consistent (same structure every time)
• The location is predictable (same channel or doc)
• The timing is reliable (always at end of day)

Start with one handoff this week. Use the format above. See if your teammate can pick up without questions. If it works, make it the standard. If it doesn't, adjust the format until it does.

The goal isn't perfection—it's reducing the friction of working across timezones. When handoffs are seamless, your team moves faster even when you're never awake at the same time.
