Pile of Indexcards

In the PoI system, the Dock works as storage : all indexcards you wrote drop into the Dock in their final stage. You don't need frustrated with "where did I put that indexcard?" kind of problem. All you need is look the Dock, then you'll find it.

This is mentioned in "Cho Seiri hou" by Noguchi Yukio, who introduced push-out filing system formally known as "Noguchi filing system". He expressed this rule as "one pocket rule". If you put somethings in a single pocket, you can find them in the pocket. On the other hand, if the pocket is two or more, you have to look all the pockets.

For example, it is convenient to put all things, that you take when you go out, in a single basket (over nighter). When you go out, you pick up keys, watch, wallet etc. from the basket. So indexcard is.

The one pocket rule prevent your productive energy from dissipation.
