The Multitasking Myth

Multitasking Is Costing Your Team More Than You Think

Do you consider yourself a multitasker? Many people do. Some are even proud of it.

But the truth is simpler and less flattering. Our brains are not wired for constant context switching.

In short: multitasking reduces output because every task switch forces the brain to reset, draining focus and energy.

Research shows it takes an average of 15 minutes to fully regain focus after switching tasks. Each interruption acts like a small cognitive restart. The result is not speed, but fragmentation. It is the mental equivalent of stopping and restarting your car repeatedly in heavy traffic. Inefficient and exhausting.

If you switch tasks just four times a day, that is roughly one hour lost to refocusing alone.

Why this matters even more for technical teams

This problem becomes critical when you look at how technical teams work.

When a remote engineer is building your product, deep focus is not optional. It is the foundation of quality work. Yet meetings, constant messages, and ad-hoc questions repeatedly pull them out of flow. Each interruption forces them to jump across contexts, slowing progress and increasing the chance of mistakes.

The cost is not just time. It is cognitive energy.

The real productivity problem isn’t effort

Most teams do not lack motivation. They lack environments that protect focus.

At illumi, our core mission is to reduce unnecessary context switching. Fewer apps. Less copy-pasting. Fewer mental jumps between tools and conversations.

The time saved does not need to be filled with more work. You can use it to build better products. Or, if you prefer, to step away and spend time with the people who matter most.

Rethinking how we design work environments

The real question is not how to make people multitask better. It is how to design systems that let them focus longer without friction.

How do we create environments that protect deep work for technical teams instead of constantly interrupting it?

We believe the answer lies in how work is structured, not in asking people to try harder.

TL;DR

• Multitasking reduces productivity because context switching drains focus and energy.
• It takes around 15 minutes to fully refocus after each task switch.
• Technical teams suffer the most when interruptions break deep work.
• Reducing app switching and fragmented workflows is one of the fastest ways to reclaim focus.
