Time Management: Chunking Technique

Jurgen Appelo Proposed the Chunking Productivity Technique @ InfoQ
"Jurgen defines a chunk of work as any focused activity lasting between approximately ten minutes and one hour, with the average being less than 30 minutes. A chunk is a well-defined activity of 10 to 60 minutes, which is either one complete task, or a portion of something bigger, or a grouping of several things smaller. He mentions three requirements for chunks:

1. They have a natural and logical start and finish;
2. They may not be interrupted (except when I’m not given a choice);
3. And breaks are welcome (even desirable) between the chunks."

Chunking technique is different from Pomodoro technique...(that) is about cutting up work into 25-minute timeboxes and then forcing yourself to take a break.

In chunking technique, unlike pomodoros, chunks have different natural sizes.

A task is done when it’s done, not when a bell is ringing."

"The pomodoro technique is like a wall of same-sized bricks. 

The chunking method is like a wall of silly-sized stones."

1. "Focus on one thing at a time and don’t let yourself be distracted.
2. If work takes more than an hour to do, cut it up in chunks that each take less than an hour to complete.
3. If you have lots of little things to do, bundle them into bigger chunks that take at least 10 minutes each.
4. Allow yourself frequent little breaks between the chunks to clear your mind and enjoy your progress and accomplishments.

That’s all there is to it, really."
