Tijdsboxing

Tijdsboxing, also known as timeboxing, is a time management technique in which a task or activity is allocated a fixed time block. Work begins at the start of the block and ends when the clock runs out, regardless of whether the task is complete. The aim is to create predictable schedules, limit overrun, and reduce perfectionism and constant switching between tasks.

Applications include personal productivity, software development, project management, and meetings. In Agile software development, timeboxing constrains work within short, fixed periods (timeboxed iterations). In meetings, timeboxing helps keep discussions focused by assigning a set duration to each topic.

How it works: first, select a task and estimate a reasonable time block. Then set a timer and begin work with focused attention. When the timer ends, stop, review progress, and decide whether to extend the block, start a new one, or move on to the next item.

Variants vary in how strictly the end of the block is treated. Hard timeboxing ends exactly at the allocated time, while soft timeboxing allows some extension or reduced scope if necessary. Timeboxing supports prioritization and reduces context switching, but it can feel rigid and may hamper creative or exploratory work.

Limitations include the need for reliable estimation, discipline to resist interruptions, and potential pressure on fast completion. The method works best when tasks can be meaningfully bounded in time and when there is a culture that respects time blocks.
