Timeboxing by Marc Zao-Sanders

Overview

"Timeboxing" is a book and methodology developed by Marc Zao-Sanders, CEO and co-founder of Filtered. Based on his research, timeboxing ranked as the most useful technique in a survey of 100 productivity methods.

What is Timeboxing?

Timeboxing is the practice of allocating a fixed amount of time to each task, then stopping when the time is up. Unlike traditional to-do lists that remain open-ended, timeboxing creates clear boundaries around work.

Research Foundation

In a 2018 Harvard Business Review article, Zao-Sanders reported that timeboxing ranked as the most useful technique among 100 productivity methods tested. The research showed that setting fixed time limits:

• Creates urgency and focus
• Reduces procrastination
• Improves time estimation skills
• Makes large projects manageable

Key Principles

1. Decide time limits in advance to avoid micro-decisions during work
2. Block time on your calendar to create commitment
3. Match time to importance not just to perceived duration
4. Stop when time expires even if incomplete
5. Review and adjust to improve future time estimates

Benefits Over Other Methods

• More specific than traditional time blocking
• More flexible than rigid scheduling
• Better for estimation than open-ended tasks
• Creates natural time tracking data

The Book

Zao-Sanders' book provides:

• Scientific evidence for timeboxing effectiveness
• Practical implementation strategies
• Solutions to common challenges
• Integration with other productivity methods

Application

Timeboxing naturally creates time tracking data as you must decide in advance how long tasks should take, then record actual time spent.
