I wish to categorise my large collection of electronic documents. I need a foolproof set of categories to put each document in. I want to use a classification system similar to how university schools are organized:
Some of my documents are productivity tips (similar to Dave Allen's "Getting Things Done" book). I can't find an academic category under which productivity comes. The term "productivity science" doesn't seem to be a widely accepted term.
What is the most natural category to put the study of "Productivity" in? Psychological Sciences (or other Social Sciences)? Applied Sciences/Professions? I'm tempted to put it in Psychology because I have other documents based on Learning, Memory and Performance. The four of those seem best suited to Psychological Sciences.
