It is frequently asked "what about
introduce Noguchi Filing to your system?". Noguchi filing system
works well to keep filing sytem dynamic. It is, however, obviously
doesn't work with the PoI system, at least for me. I knew this fact
empilically. I had struggled how to explain this for people, and
even for myself.
After jeevs gave me constructive comments at flickr, I clearly realized
why it doesn't work.
In the Noguchi filing system, number of
file added in the system is, though it is largely depends on a
person, couple of files per day, or even lesser. Plus, several
piece of files are compiled in an envelope. It reduces number of
file in the system. A review is more frequent than file addition.
It can be expressed following simple equation.
Noguchi : Frequency of adding
files < Frequency of review
In the PoI system, number of cards
increase with the order of ten, much more faster than filing system
everyday. In addition, there is nothing to compile each card ;
information is naked. For review process, I do it not in constant
like "week review" but when I need or just want it. The frequency
is once per two weeks or even lesser. If I introduced Noguchi type
review rules to the PoI system, the revised cards are easily buried
by new cards (seen picture above). This situation is expressed
as,
PoI :
Frequency of adding card >> Frequency of
review
The only difference of the two equations is the sign of inequality. But it makes huge difference between the two system. Noguchi filing system works well for the sign "<" (or "=") and not for ">>".
