Why Context Switching Destroys Your Productivity (And How to Stop)
The real cost of jumping between tasks isn’t what you think. We break down the research and show exactly where you’re losing time.

14 years helping Hong Kong professionals reclaim focus through batch processing and workflow optimization. We’re talking about real systems that actually work—not theory, not apps, just better ways to work.
How a frustration in investment banking became a framework that’s now used across Hong Kong’s most demanding industries
Marcus’s journey into workflow optimization wasn’t planned. It started in 2010 at a Hong Kong investment bank where he noticed something obvious but nobody was talking about: his team was losing about 12 hours every week to context switching. Not meetings. Not emails necessarily. Just constantly jumping between tasks, losing focus, restarting work they’d already started.
He started experimenting with batch processing during his own work. Grouping similar tasks. Processing emails in blocks instead of constantly. Dedicating specific times to specific types of work. Within weeks, he noticed a shift. He wasn’t working longer hours—he was working differently. More focused. Less scattered.
That observation became an obsession. He spent the next few years refining what works and what doesn’t, testing on himself first, then on willing colleagues, then on entire teams. By 2014, he’d developed a framework that was repeatable—not because it was complicated, but because it was built around how people actually work, not how productivity books say they should work.
“The real breakthrough wasn’t inventing something new. It was realizing that most people already know how to batch process—they just don’t do it intentionally. We help them make it intentional.”
— Marcus Wong
Since then, he’s worked with over 200 Hong Kong-based companies across finance, logistics, professional services, and corporate operations. His clients aren’t looking for a trendy app or a motivational system. They’re looking for something that works in their actual environment—where meetings stack up, where interruptions are constant, where you need to stay responsive but also need to do deep work.
Marcus holds a Bachelor’s in Business Administration from the University of Hong Kong and an MSc in Organizational Psychology from Hong Kong Baptist University. He’s published research on context switching costs in the Asia-Pacific region and regularly presents at business conferences across the SAR. But his real credential is what his clients will tell you: he doesn’t sell perfection. He sells what works.
What Marcus helps professionals and teams master
Grouping similar tasks together to eliminate constant context switching. This isn’t about being rigid—it’s about being intentional with your attention.
Understanding the actual cost of jumping between tasks and building workflows that minimize unnecessary switches. The research shows it matters more than most people realize.
Structuring your day around work types rather than clock times. Email blocks, deep work blocks, meeting blocks—all designed to protect focus where it matters.
Building systems that stick because they’re built on your actual working style. Not systems that require you to change who you are.
Helping teams and organizations redesign how work flows through their systems. From email protocols to meeting structures to handoff processes.
The philosophy behind everything he builds
Marcus doesn’t begin with theory. He starts by understanding your actual environment—what interrupts you most, where your biggest time leaks are, what constraints you can’t change. This matters because a system that works for a CFO in a bank won’t work the same way for a logistics manager.
Most people try to optimize tasks that should never be done individually in the first place. Batch processing comes first. Group your emails. Group your administrative work. Group your communication tasks. Once you’ve done that, then you optimize the batch itself.
You don’t need another tool. You probably already have everything you need. What you need is a system—a set of rules about when you do what, and why. That’s something no app can give you. Only you can build that.
Systems fail when they require you to be someone you’re not. If you’re not a morning person, don’t build a 5am routine. If you work better in long blocks, don’t fragment your day. The best system is one that works with your actual temperament, not against it.
“The best workflow system isn’t the one that’s theoretically optimal. It’s the one you’ll actually use six months from now because it fits how you actually work.”
