It is easy to produce impressive quantities of paper by documenting the very obvious and/ or completely useless.
Spend lots of time on the appearance and presentation of your documentation. Your management is easily distracted by shiny things, and will not realize that your binders contain information that could easily be recreated by anyone.
Creating bad documentation is time consuming, and makes you look very busy. You can use your documentation as an excuse to avoid real work, or perhaps to con a few more days of employment.
One insidious consequence of overly detailed documentation is the maintenance required. Recording trivial changes is very time consuming. However, unmaintained documents quickly become inaccurate and misleading, and arguably worse then no documentation at all.
