Every documentation system I've ever seen at any company -- large or small -- is almost always undermined by the inclination to: 1) not look things up, and 2) ask someone before looking things up.

The information is almost always 3 clicks away, but people just want to ask another person, or behave in a paralyzed manner as if the information couldn't possibly be found.

And if you work in a "lotta meetings" company culture, even moreso.
