Drawing up a monitoring plan

A classification plan (we're talking here about documents that have been collected, validated and capitalized on) is relatively hierarchical and one-dimensional, even if some intelligence solutions allow you to classify the same information under several headings without duplicating it.

However, there are different ways of providing a cross-sectional reading of your filing plan, at the level of the information, of the item itself.
